Where 310S stainless steel excels is when pipework is exposed to extreme temperatures that standard stainless steel may not be able to withstand. It is designed for high-temperature service, ensuring that your stainless steel pipe and stainless steel fittings are built to last.
What Is 310S Stainless Steel? Your High-Temperature Hero!
310S stainless steel (UNS S31008) is a low carbon version of 310 stainless steel. It is an austenitic chromium-nickel alloy. The high chromium and nickel content gives it excellent properties. It resists oxidation and corrosion at high temperatures. The low carbon content minimises carbide precipitation during welding.
Key Advantages of 310S Stainless Steel
It is reliable and can withstand temperatures up to 1100 °C (2012 °F) while preventing scale and oxidation.
The high chromium content creates a stable oxide layer to protect the surface. Prevents degradation in an oxidising environment.
310S stainless steel resists creep deformation and retains its shape under prolonged stress. This is true even at elevated temperatures.
Low carbon content is key to reducing carbide precipitation during welding. This minimises the risk of intergranular corrosion.
Maintains mechanical properties well and prevents embrittlement. This can occur with prolonged exposure to high temperatures.

310S Stainless Steel in High-Temperature Applications
- Furnace Components: Widely used in heat treatment furnaces, such as radiant tubes, mufflers and burners. Can withstand sustained high temperatures.
- Heat Exchangers: Pipes and tubes in high-temperature heat exchangers benefit from effective heat transfer and resistance to oxidation.
- Thermal Processing Equipment: Including furnaces and ovens. 310S stainless steel ensures the ability to cope with thermal cycling in extreme environments.
- Low Temperature Applications: Surprisingly, 310S stainless steel performs well at very low temperatures and maintains good toughness.
Sourcing 310S Stainless Steel Pipe and Fittings
Check for compliance with ASTM standards. ASTM A312 covers seamless and welded stainless steel pipe. ASTM A403 covers wrought austenitic stainless steel fittings.
Ensure that pipes and fittings meet the required dimensions. This includes specifications (e.g., Sch 10S, Sch 40S). Proper fit is critical.
View Stainless Steel Tube Specification Document
Work with reputable manufacturers who offer reliable 310S steel products and have certifications(e.g. ISO 9001 and CE-PED).
Always ask for Material Test Reports, which confirm chemical composition and verify mechanical properties.
Although weldable, some applications may require specialised post-weld treatment or stress relief.
