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. 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 offers excellent weldability using all common methods including submerged arc welding. Recommended weld fillers include AWS ER347 bare wire and E347 covered electrodes. With a machinability rating of 45% relative to AISI B1112, 321 stainless steel machines similarly to 304 stainless steel.

Possible 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 |
