Heat-Resistant Stainless Steel for Boilers & Heat Exchangers

Boilers and heat exchangers expose the tube and shell sides to different fluids, temperature gradients and cleaning conditions.

Common Components

Tube sections, tubesheets, baffles, tube supports, flanges and machined connections.

We supply tube, plate, sheet, bar, forgings, flanges, fittings and machined parts; tube testing and end preparation follow the order.

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

Creep and pressure stress differ from water-side corrosion and thermal fatigue at joints. Dry hot-gas performance does not predict resistance to condensate or cleaning chemicals.

Choosing a Grade

310S and 253MA are comparisons for suitable hot-gas components. Compare 321/347 and 321H/347H for stabilized or creep-governed duties, and 316Ti for suitable corrosion conditions. Pressure-retaining tubes, plates and connections require the specified code, product form and heat treatment.

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.
