Grade 321 / 321H Stainless Steel Overview
321 stainless steel is a titanium-stabilized austenitic grade specifically designed for service in the 1000-1600°F temperature range. This stabilization provides excellent resistance to intergranular corrosion and polythionic acid stress corrosion cracking.
Welding & Machining: Readily welded by all common methods including submerged arc. Appropriate weld fillers are AWS ER347 bare wire and E347 covered electrodes. Machinability rating of 45% relative to AISI B1112.
Product Forms
Sheet, plate, coil, strip, wire, pipe, tube, bar, profile, round, flat, square, hexagonal.
