Furnace and heat-treatment parts face hot gases, repeated heating and cooling, and loads that vary between liners and charged trays.
Liners, baffles, annealing boxes, trays, radiant-tube parts and supports.

Material Risks
Oxidation consumes the surface; restrained thermal expansion can distort joints. Loaded trays and supports also need creep assessment, separate from air-oxidation resistance.
Choosing a Grade
Compare 309/309S with the higher-chromium/nickel 310/310S family for oxidation service. 310Si2 and 309Si2 offer silicon-alloyed options for air-exposed liners and annealing boxes. Compare 253MA for cyclic oxidation and creep; 321/347 and their H variants require a separate load and temperature assessment. Reducing sulfur and strongly carburizing atmospheres need specific evaluation.
Typical Furnace Components
Component & Geometry
We supply plate, sheet, coil, strip, tube, bar, forgings and drawing-based parts, with cut blanks and formed sections for furnace assemblies.
Scroll horizontally to see every column.
Send a drawing or component description, operating conditions and quantity. We will confirm material, processing and inspection options for your project.
Start with the 310S material hub, then choose the product form that matches the bill of materials. The order still needs its product standard, dimensions, condition, quantity and inspection scope.
Product forms: We supply 310S / UNS S31008 / EN 1.4845 as hot- or cold-rolled sheet and coil, hot-rolled plate or quarto plate, subject to the requested standard, dimensions, condition, quantity and inspection scope. State the required product standard and form in the RFQ.
We arrange cutting, bending, rolling, machining and welding preparation to the drawing. Our group and partner resources support the agreed geometry, tolerances and assembly scope.
Inspection & Traceability
We provide heat-linked material documents and dimensional and surface checks. PMI, NDT and third-party inspection can be arranged to the agreed order scope; test methods and acceptance criteria are confirmed before production.
Document basis: When EN 10204 inspection documents are required, name the document type in the RFQ and keep product tests, supplementary checks and third-party attendance as separately agreed order requirements.
Packing & Delivery
We protect surfaces, edges and machined faces, cap tubular ends and support long or formed parts. Package identification follows the drawing items and planned installation sequence.
Your Equipment Project
Send a drawing or component description, operating conditions and quantity. We will confirm material, processing and inspection options for your project.
We normally reply within 1 business day. Technical enquiries may require additional review.
Frequently asked questions
Is 310S automatically suitable for every industrial furnace component?
No single grade decision covers every furnace. Evaluate the atmosphere, temperature profile, cycling, load, deposits, geometry, joining method and governing design rules before project engineering approves 310S.
What operating information should I send for material selection?
Send the furnace zone and component function, gas or process atmosphere, continuous and peak temperatures, cycle frequency, deposits, mechanical load, restraint, cleaning method and planned maintenance interval.
Which 310S product forms can be considered for furnace parts?
We supply plate and sheet for liners, baffles, shields, supports and formed sections, and pipe or tube for radiant-path and tubular parts. State the product standard, dimensions, ends and test scope in the RFQ.
Can Hechuang Stainless Steel coordinate cutting, forming and welding preparation?
Yes. Send the drawing and identify cut quality, bend or roll geometry, joint details, machining allowance, WPS/PQR requirements, finished tolerances, surface acceptance and inspection points so we can quote the complete fabrication scope.
What inspection and documentation can be included?
An enquiry can include the ordered MTC type, heat traceability, dimensions, surface and cut-edge checks, PMI, agreed NDT, fabrication records and third-party witness points. State each requirement before quotation.
