Heat-Resistant Stainless Steel for Petrochemical

Fired-heater auxiliaries and process piping share a plant but face different atmospheres, pressures and corrosion conditions.

Common Components

Burner shields, heater baffles, tube supports, process spools, flanges and connection parts.

We supply plate, tube, bar, forgings, flanges, fittings and machined or fabricated parts, identified by drawing or line item.

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.

Material Risks

Hot oxidation differs from sulfur attack, carburization and wet process corrosion. A shield material cannot establish the allowable stress or corrosion margin of a pressure boundary.

Choosing a Grade

309S/310S are comparisons for hot, oxidizing heater auxiliaries. Compare stabilized 321/347 for welded elevated-temperature parts and 321H/347H where creep strength governs. Consider molybdenum-bearing 316Ti for suitable corrosive media. Pressure parts follow the selected code, product standard and actual process chemistry.

Processing Support

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.

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.
