Stainless Steel 321/321H

321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600°F temperature range. For service temperatures up to about 1600°F, a stabilizing treatment at 1550-1650°F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.
Product information
Stainless Steel 321 Sheets can be welded using most of the resistance and fusion methods. Stainless Steel 321 Plates also possesses good low temperature toughness and is non-magnetic in the annealed condition. In addition to its heat resistance properties, Stainless Steel 321 Coils also enjoys better resistance against creep and stress rupture corrosions. Stainless Steel 321H Sheets is used in Oil Refineries, Fluid catalytic cracking units, Hanger rods, and more. Like most other austenitic alloys, Stainless Steel 321H Plates work hardens and may require annealing after severe forming. Niobium in Stainless Steel 321H Coils has been added to suppress grain boundary Chromium Carbide precipitation.
