321 Stainless Steel Coils

Types 321 Stainless Steel Coils is 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 321 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.
