Grade 321 Stainless Steel Overview
321 stainless steel is a titanium-stabilized grade designed for service in the 1000-1600°F temperature range. This stabilization treatment provides optimum resistance to intergranular corrosion and polythionic acid stress corrosion cracking.
Excellent weldability using all common methods including submerged arc. Appropriate weld fillers include AWS ER347 bare wire and E347 covered electrodes. Machinability rating of 45% relative to AISI B1112.

- Thermal oxidizers
- Refinery equipment
- High temperature chemical process equipment
Alternative Grades Comparison
| Grade | Why it might be chosen instead of 321 |
|---|---|
| 304L | Requirement for resistance to intergranular corrosion, not for high-temperature strength |
| 3CR12 | Only mild "high temperature" environment up to about 600°C |
| 304H | Only mild "high temperature" environment up to about 800°C |
| 310 | Operating environment up to about 1100°C - too high for 321 or 321H |
| S30815 (253MA) | Operating environment up to about 1150°C - too high for 321 or 321H |
