|---|---|---|---|---|---|
| 321 | S32100 | 321S31 | 1.4541 | 2337 | SUS 321 |

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 |
