321-cold-rolled-stainless-steel-coil is basic austenitic stainless steel contains 18% chromium, 8% nickel and addition of titanium. The addition of titanium offers stabilized products and improves intergranular corrosion resistance. Apart from this 321-cold-rolled-stainless-steel-coil have excellent resistance to scaling, high tensile strength and phase stability to aqueous corrosion.

Like other austenitic grades, 321-cold-rolled-stainless-steel-coil have excellent forming and welding characteristics, are readily brake or roll formed and have outstanding welding characteristics. Post-weld annealing is not required. They also have excellent toughness, even down to cryogenic temperatures. 321-cold-rolled-stainless-steel-coil does not polish well, so is not recommended for decorative applications.
