Stainless Steel 310S Pipe
Product Description
310S heat-resistant stainless steel pipe, also known as TP310S or 1.4878, is an austenitic chromium-nickel stainless steel, resistant to high temperature and corrosion, containing 24-26% Cr, 19-22% Ni, density 7.98g/cm³, melting point 1398-1454°C, strength ≥520MPa.
310S stainless steel seamless pipe has a maximum operating temperature of 1200℃ and a continuous use temperature of 1150℃. It can still maintain creep strength at high temperatures, and a dense oxide film is formed on the surface, which effectively resists high-temperature oxidation. It has good corrosion resistance to acid and alkali environments, but its chloride ion corrosion resistance is weaker than 316L.
Application Of 310S Stainless Steel Boiler Tubes
- Industrial high temperature equipment: furnace tubes, furnace nets, incinerator parts.
- Chemical and energy: reactors, heat exchangers, oil cracking units.
- Special fields: nuclear power, aerospace, LNG storage tanks.

FAQ
Q: What should be noted when welding 310S?
A: Wire selection: ER310S or E310S electrodes are recommended. Use argon arc welding (TIG) or manual arc welding (SMAW) to avoid carbon contamination.
Q: What is the common specification range of 310S?
A: Outer diameter: 6mm to 2540mm. Wall thickness: 0.5mm to 60mm. Surface treatment: industrial surface, matte surface (electrolytic polishing).
Q: Is 310S easy to process?
A: 310S stainless steel cold-processed pipe: can be bent and stamped, but requires greater force to avoid cracking. 310S stainless steel hot-processed pipe: good ductility at high temperature, suitable for forging or rolling.
