Heat-Resistant Stainless RFQ Checklist: From Grade to Delivery

Initial contact does not need a complete engineering dossier. For a standard product, send the grade, form, dimensions, quantity and destination; write “not sure—please advise” for an open standard, condition or document choice. A formal quotation adds the confirmed technical scope and commercial fields such as destination, Incoterm, payment and schedule. For material selection or drawing-based work, also add metal temperature, atmosphere, load, fabrication, tolerances and inspection requirements. The checklist turns the first conversation into an order-ready quotation without making incomplete information a barrier to contacting us.

Use the shortest path that fits the purchase

Two practical ways to start

Enquiry type	Send now	Add during technical follow-up
Standard plate, sheet, coil, pipe, bar or other known product	Grade, form, dimensions, quantity and destination	Standard, condition, finish, MTC and packing if they are still open
Selection, replacement or fabricated component	Available drawing or photo, duty, metal temperature, atmosphere, load, quantity and destination	Final grade, product standard, tolerances, WPS, inspection and decision requirements

Unknown fields can remain open as not yet defined or please advise in an initial enquiry. Mark them clearly instead of selecting a standard or document type by guesswork. We can confirm what we supply first, then help organize the remaining purchasing inputs for the quotation.

For initial contact, the practical minimum is grade, product form, dimensions, quantity and destination. Keep an unresolved field open as not yet defined, please advise or supplier to propose. For a formal quotation, confirm the applicable standard, condition, tolerance, processing, inspection and document package together with the commercial basis, including quantity, destination, Incoterm, payment terms and required schedule. The purchase order then repeats the accepted technical and commercial scope.

Grade

Use the exact approved material identity

Write the grade exactly as it appears in the approved drawing or material specification. Include the designation system and any condition or grade suffix that affects procurement. A commercial family name alone can hide differences in chemistry, product availability or acceptance rules.

If the buyer is requesting help with material selection, say so and provide operating and peak temperature, atmosphere or process media, continuous or cyclic operation, deposits, abrasion, load, pressure, section size and fabrication plan. A supplier can then propose a supply option for engineering assessment and identify it clearly as an alternative requiring written approval.

Use [exact grade designation] as a placeholder in a template, then replace it with the real project input. Do not invent a cross-standard name. If alternatives are allowed, state who may approve them and require the quotation to list every difference.

A useful RFQ does not have to be long. We often receive workable enquiries with one drawing and a short material list because the buyer marks what is fixed and what the supplier should propose. The requests that take longest to clarify usually mix mill and finished-part tolerances, omit the product standard, or add the inspection document after the documentation plan has been set.

Standard

Pair the grade with the product standard

The product standard defines the ordered product scope and acceptance requirements. ASTM’s official catalogue shows separate families for plate, sheet and strip, tubular products, bars, forgings, flanges, fittings and other steel products. Choose the standard that matches the actual form rather than copying a familiar flat-product reference onto every item.

State the full designation and edition required by the project. Add the dimensional standard, project specification or design code when it controls another part of the purchase. If the latest edition may be proposed, say how the buyer will review a change before award.

The RFQ can use [governing product standard and edition] until the controlled input is available. Do not use a withdrawn comparison compilation or a public crosswalk to assert automatic equivalence. The detailed current standard and approved project documents control acceptance. When project documents name more than one standard, state their hierarchy or raise a technical query instead of leaving the supplier to choose the acceptance basis.

Form

Choose the purchasable form

State plate, sheet, coil, strip, pipe or tube, bar, forging, flange, fitting or custom part. For pipe or tube, add seamless or welded construction. For a flange or fitting, add type and end configuration. For a custom part, identify the intended source form if engineering has fixed it, or ask the supplier to state the proposed source.

The form changes the production method, dimensional rules, condition, processing allowance, test scope, traceability and packing. Treat flat, tubular, long and forged products as separate order lines, each with its own standard, dimensions, condition, test scope and packing requirements.

Use the product-form selection guide when the finished geometry could be sourced from more than one form.

Dimensions

State the complete dimensional basis

Use dimensions that match the form: thickness × width × length for plate or sheet; thickness × width plus coil data for coil or strip; OD or NPS × wall or schedule × length for tubular products; diameter or section × length for bar; and the applicable standard dimensions for flanges or fittings.

For forgings and custom parts, prepare a controlled drawing or model with revision, units, datum scheme, blank dimensions, finished dimensions and machining allowance. Identify quantity per item and whether dimensions are nominal, minimum, maximum or finished.

If dimensions are not fixed, retain placeholders such as [thickness] × [width] × [length] or [OD/NPS] × [wall/schedule] × [length] and mark the field not yet defined or supplier to propose. Replace the placeholders with real project data before the formal quotation or order is confirmed.

Tolerance

Separate mill tolerance from finished tolerance

State which tolerances follow the product standard and which are additional. Plate thickness, sheet flatness, strip width, tube wall, bar straightness and flange dimensions belong to different standards and measurement methods. Name any dimensional standard, drawing tolerance or general tolerance class that applies.

Processed items need finished-part tolerances. Define critical features, datum references, profile, flatness, roundness, concentricity, straightness, hole position, bevel or facing requirements as appropriate. Do not assume that cutting or machining accuracy is automatically the same as the requested part tolerance.

Ask the supplier to identify exceptions and measurement-access limitations in the quotation. If several tight requirements interact, request a manufacturing review before the order is accepted.

Surface

Describe the required condition and protection

State the mill condition, surface finish, roughness or appearance, grain direction, pickling or descaling, edge condition, end preparation and protective film where relevant. A finish number alone may not define the buyer’s visual or functional requirement.

For fabricated parts, add acceptable heat tint, weld cleanup, grinding direction, contamination control and passivation or cleaning requirements when the project calls for them. For machined flanges and fittings, identify facing finish and protected surfaces. For tube, state bore cleanliness or end protection if needed.

When appearance is critical, define an approved sample or clear acceptance reference. Specify how surfaces are inspected and how packing prevents rubbing, moisture exposure or edge damage.

Quantity

Give line-item and total demand

State quantity for every size and form in pieces, metres, kilograms, metric tons, coils, bundles or sets as appropriate. Add acceptable piece, coil or package weight where handling equipment sets a limit. If partial shipments are allowed, define the permitted split.

Hechuang’s usual MOQ is 1 metric ton across sizes quoted together. Multiple sizes do not automatically need to reach 1 metric ton individually. Special orders below 1 metric ton are negotiable. Grade, product form, dimensions, material source, processing, inspection and packaging can still change what is practical, so the quotation must confirm the applicable minimum and quantity basis.

Free samples are available with freight paid by the customer. They can be cut to an agreed size and normally require 3–7 days to prepare after the sample requirement is confirmed. A sample checks a defined purpose; it does not certify the chemistry, properties or production method of a future order.

Processing

Define the supplier’s delivered scope

List cutting, slitting, leveling, forming, rolling, beveling, drilling, machining, welding, heat treatment, pickling, passivation, polishing or assembly required from the supplier. Work from the controlled drawing and identify which dimensions are before and after processing.

State bend radii, forming direction, weld procedure or qualification requirements, machining allowance, finished surface and any prohibited repair. If the buyer will perform processing, describe the downstream process when it helps the supplier review condition, flatness, edge or allowance.

Ask the supplier to identify the proposed source form, equipment sequence and outsourced scope where relevant. Availability and tolerance should be confirmed as one combination. A published machine maximum and a published minimum tolerance may belong to different setups.

Inspection

Build an order-specific inspection plan

State dimensional, visual, surface, PMI, NDT, hydrostatic, mechanical, corrosion or other inspection requirements that follow from the ordered standard and project. Identify the acceptance basis, sampling, report format and release point. Do not add tests merely because they appear on a generic checklist.

If third-party inspection is needed, name the agency or permitted agencies, scope, witness or hold points, notice period, location, report and cost responsibility. Confirm access and timing before production. Require the inspector’s report and the manufacturer’s specified material documents as separate deliverables unless the governing requirement says otherwise.

For custom parts, separate material inspection from processing inspection. Heat traceability, dimensions, weld records and NDT may be different deliverables linked to one item.

MTC

Name the exact document requirement

Write the required inspection-document type rather than only “MTC required.” State whether the document must show the grade, product standard, heat or lot, chemistry, mechanical results, dimensions or other fields required by the order. Add language, copies, electronic format, submission timing and approval requirements.

Define how heat or lot identifiers transfer through cutting, slitting, machining and fabrication. Ask for a material map when several heats or source forms enter an assembly. The delivered document must match the actual goods; a public sample or producer datasheet cannot certify the order.

For EN 10204 requests and review steps, use the inspection-document guide. Obtain supplier confirmation for the actual mill and product form before order acceptance.

Packing

Protect geometry, finish and identity

Specify bundle, crate, skid, reel, coil-eye, end-cap, face-cover, separator, moisture barrier or other packing needed for the form and transport. Identify lifting, stacking, package-weight and forklift restrictions. Unusual shapes may need a packing drawing.

Protect plate and sheet faces and edges; stabilize coils and strip; protect tube bores and ends; support long bars; and cover machined flange faces or fitting bevels. Keep dissimilar finished surfaces from rubbing during transport.

State required marks, tags, item numbers, heat or lot identifiers and packing-list links. When marking cannot remain on a finished surface, define a controlled alternative that preserves traceability.

Destination

Give the final delivery point

Provide city, country, postal code and site or port details needed for the quotation. Include delivery restrictions, consignee requirements, project name only when authorized, and any deadline for shipping documents. The destination affects freight, packing, shipping plan, documentation and sometimes feasible package size.

Common export ports are Shanghai and Ningbo. They are normal routing options, not mandatory ports for every shipment. Ask the quotation to name the proposed loading port and any inland leg.

Even for EXW, tell the supplier the intended destination and collection constraints. That information helps prevent a package design that cannot move through the buyer’s planned logistics chain.

Incoterm

State the rule and named place

Hechuang’s normal Incoterm options are FOB, CIF, CFR, DAP and EXW. State the selected rule, named port or place and the required Incoterms edition. Do not write only “FOB” or “DAP” without the named location.

Clarify whether the quotation includes export packing, inland transport, customs documents, ocean freight, insurance or delivery to site as appropriate to the term. Identify any buyer forwarder or booking instructions after award.

Normal payment options are T/T or L/C at sight. The quotation and final order should confirm currency, deposit or payment milestones, banking requirements, document presentation and any effect on production or release.

Schedule

Separate response, preparation, production and transit

Hechuang responds to website enquiries within one business day. That response begins the review; it is not a promise that a technically complete offer or mill confirmation is available within the same period when drawings, standards or special tests need clarification.

Available-stock orders normally require 3–7 calendar days from receipt of the deposit until the material is prepared and ready for dispatch from Hechuang’s facility. Mill-order production normally requires 30–60 calendar days from receipt of the deposit until production is complete and the material is ready for dispatch. Processing, special inspection and international transit are separate where applicable. Free cut samples normally require 3–7 days of preparation, with customer-paid freight. These are normal planning ranges subject to product and order confirmation, not fixed promises or evidence that every item is in stock.

State the required ex-works date, shipping date or site date clearly. Add drawing approval, sample, inspection notice, witness, document approval and partial-shipment milestones where relevant. Ask the quotation to separate production lead time from transit.

Convert Requirements into a Quotation

Convert requirements into one controlled offer

Use this sequence to turn the technical request into comparable quotation lines:

1. engineering confirms grade, product standard, form and service inputs;
2. the buyer separates mill dimensions from finished dimensions and tolerances;
3. processing, inspection, MTC, marking and packing are added to each line item;
4. commercial fields define quantity, destination, Incoterm, payment and schedule;
5. the supplier identifies the offered mill or manufacturing method and all deviations;
6. the named authority reviews alternatives before award;
7. the purchase order repeats the accepted technical and commercial terms; and
8. receiving matches the delivered goods and document package before release.

Use [field] placeholders while drafting, then replace every placeholder with the approved project information before sending the RFQ.

Copyable Final Checklist

Complete every bracketed field

Copy this structure into the enquiry:

Illustrative example — not a customer order: 310S plate, 8 × 1,500 × 6,000 mm, 12 pieces, delivery to Hamburg. Applicable ASTM/EN standard and MTC type not yet fixed—please quote the available stock option and state the offered standard, condition, document type, lead time and packing. This is enough to start a useful sales conversation; the bracketed checklist below is for completing the order-ready version.

Material: [exact grade] to [product standard and edition], [condition / heat treatment].
Form: [plate / sheet / coil / strip / pipe / tube / bar / forging / flange / fitting / custom part], [construction or type].
Dimensions: [complete mill dimensions], [drawing number and revision], [finished dimensions].
Tolerance and surface: [standard tolerance], [additional tolerance], [finish / roughness / edge / ends / protective film].
Quantity: [quantity for each line], [unit], [piece / coil / package limits].
Processing: [cutting / forming / welding / machining / heat treatment / finishing].
Inspection and MTC: [document type], [traceability], [tests and reports], [third-party scope and hold points].
Packing and marking: [packing method], [marks / tags], [weight and handling restrictions].
Delivery: [destination], [Incoterm and named place], [required date], [partial shipments].

Service inputs: [temperature], [atmosphere / media], [cycle], [load / pressure], [fabrication plan] where material review is requested.
Deviations: list every proposed alternative or exception for written approval before order acceptance.

Prepare the controlled drawing, specification, bill of materials and inspection plan where applicable. Do not leave a placeholder in the sent request if the missing field affects price or plan. If an input is genuinely open, label it “supplier to propose” and name the approval authority.

Send your dimensions and requirements through the full RFQ form; drawings and specifications can be attached optionally. The final quotation should confirm the offered product and form, MOQ, sample arrangement if requested, processing, inspection, payment, Incoterm, port and schedule for the actual enquiry.

Conclusion

A reviewable heat-resistant stainless RFQ connects technical and commercial decisions. Start with the exact grade, governing product standard and form. Add dimensions, tolerances, surface, quantity, processing, inspection, MTC, packing, destination, Incoterm and schedule without mixing mill and finished-part requirements.

Use the normal service terms when preparing the enquiry: usual MOQ 1 metric ton across sizes quoted together, with sub-tonne special orders negotiable; free cut samples with customer-paid freight and 3–7 day preparation; available-stock preparation normally 3–7 calendar days from deposit receipt to dispatch readiness; mill-order production normally 30–60 calendar days from deposit receipt to production completion and dispatch readiness; international transit separate; T/T or L/C at sight; FOB, CIF, CFR, DAP or EXW; common ports Shanghai and Ningbo; and a one-business-day website-enquiry response. Every material, availability, processing, inspection and delivery detail remains subject to the real product and order confirmation.

Replace the checklist placeholders with approved inputs and use the RFQ link. Require the offer to identify the proposed specification and deviations before the purchase order is placed.
