Types 310 Stainless Steel and 310S are typically used for elevated temperature applications. Their high nickel and chromium contents impart excellent elevated temperature strength and resistance to oxidation compared to Type 304 SS. Type 310S Stainless Steel is identical to Type 310 except for a lower carbon content that minimizes carbide precipitation and improves weldability. They are essentially nonmagnetic as annealed and become lightly magnetic when cold worked.
