310S Stainless Steel Coil and Sheet

Type 310S, a low-carbon version of Type 310, is easy to manufacture due to its better formability and weldability. It is a high-temperature chromium-nickel austenitic stainless steel with high creep strength and excellent oxidation resistance in mild dry conditions up to 2000°F, which has good sulfur resistance and good carburizing resistance in a moderate carburizing atmosphere. Thanks to its high nickel-chromium content, 310S outperforms 304/304L or 309 in most environments. Stainless steel 310S is non-magnetic under annealed and cold working conditions.

310S Stainless Steel Coil and Sheet Basic Information

Sanmei Metal Stainless Steel inventory includes 310S in coil and sheet.

310S is equivalent to

ASTM: 310S
AISI: 310S
JIS: SUS310S
EN: 1.4845
DIN: X15CrNiSi25-20
UNS: S31008

310S Stainless Steel Processing

Corrosion Resistance of 310S Stainless Steel

Excellent resistance to oxidation and corrosion, particularly at high temperatures.

Heat Resistance of 310S Stainless Steel

Superior high-temperature properties. Can withstand temperatures up to 1150°C in continuous service.

Machinability of 310S Stainless Steel

Fair machinability, similar to 304 stainless steel. Carbide or ceramic tooling is recommended.

Welding of 310S Stainless Steel

Weldable using all standard processes. Special care is needed due to its high thermal expansion to prevent warping and distortion.

Hot Working of 310S Stainless Steel

Hot working should be performed at temperatures ranging from 2100 – 2300°F (1149 – 1260°C). Post-hot working annealing is recommended.

Cold Working of 310S Stainless Steel

310S can be cold-worked but is not commonly done due to its work-hardening rate. Cold working is the only method to harden this alloy.

Annealing of 310S Stainless Steel

Annealing should be done at 1900 – 2050°F (1040 – 1120°C) followed by rapid cooling.

Hardening of 310S Stainless Steel

Cannot be hardened by heat treatment. Can only be hardened through cold working.

310 vs 310S Stainless Steel, Choose Which One?

Choosing the right type of stainless steel for different applications is crucial. There are the differences between 310 and 310S stainless steels to help you make an informed decision.

They both:

310 and 310S stainless steels share high-alloy austenitic properties with excellent high-temperature and corrosion resistance due to their high chromium and nickel content.

Differences:

The key difference is in carbon content: 310 has lower carbon (about 0.25%), while 310S has even less (up to 0.08%), enhancing 310S's weldability and resistance to high-temperature intergranular corrosion.

Application:

310 is suited for high-strength applications in extreme heat like furnaces, while 310S, with superior weldability and corrosion resistance, excels in environments needing both properties, such as chemical processing and heat exchangers.
