Grade 321 / 321H Stainless Steel Overview

321 stainless steel is a titanium stabilized grade designed for service in the 1000-1600°F temperature range. For optimal resistance to intergranular corrosion and polythionic acid stress corrosion cracking, a stabilizing treatment at 1550-1650°F followed by air cooling is recommended.

This grade is readily weldable by all common methods including submerged arc, using AWS ER347 bare wire and E347 covered electrodes. With a machinability rating of 45% relative to AISI B1112, it offers similar machining characteristics to 304 stainless steel.

Available Product Forms

Sheet, Plate, Coil, Strip, Wire, Pipe, Tube, Bar, Profile, Round, Flat, Square, Hexagonal

Alternative Grades Comparison

Grade	Why it might be chosen instead of 321
304L	When resistance to intergranular corrosion is required, but not high-temperature strength
3CR12	For mild high-temperature environments up to about 600°C
304H	For mild high-temperature environments up to about 800°C
310	For operating environments up to about 1100°C - too high for 321 or 321H
S30815 (253MA)	For operating environments up to about 1150°C - too high for 321 or 321H
