| 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 temperature up to about 1100°C - too high for 321 or 321H |
| S30815 (253MA) | Operating environment temperature up to about 1150°C - too high for 321 or 321H |
