China 321 Cold Rolles Stainless Steel Coil with 2b Finish ASTM AISI En DIN JIS GB

321 Hot Rolled Stainless Steel Coil

Introduce
Like other austenitic grades, 321 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. Grade 321 does not polish well, so is not recommended for decorative applications.
