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 performance at temperatures up to 1600°F, a stabilizing treatment at 1550-1650°F with air cooling is recommended to provide maximum resistance to intergranular corrosion and polythionic acid stress corrosion cracking.

This grade is readily weldable using all common methods including submerged arc welding. Appropriate weld fillers include AWS ER347 bare wire and E347 covered electrodes. With a machinability rating of 45% relative to AISI B1112, 321 stainless steel offers similar machining characteristics to 304 stainless steel.

Alternative Grades

Grade	Why it might be chosen instead of 321
304L	The requirement is for resistance to intergranular corrosion, not for high-temperature strength
3CR12	Only a mild "high temperature" environment is present… up to about 600°C
304H	Only a mild "high temperature" environment is present… up to about 800°C
310	The temperature of the operating environment is up to about 1100°C - too high for 321 or 321H
S30815 (253MA)	The temperature of the operating environment is up to about 1150°C - too high for 321 or 321H
