Grade 321 / 321H Stainless Steel Overview
321 stainless steel is a titanium stabilized 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 followed by air cooling is recommended to provide maximum resistance to intergranular corrosion and polythionic acid stress corrosion cracking.
Manufacturing & Processing: 321 stainless steel is readily welded by all common methods including submerged arc. Appropriate weld fillers include AWS ER347 bare wire and E347 covered electrodes. With a machinability rating of 45% relative to AISI B1112, it offers similar machining characteristics to 304 stainless steel.

Grade Specification Comparison

|---|---|---|---|---|---|
| 321 | S32100 | 321S31 | 1.4541 | 2337 | SUS 321 |
| 321H | S32109 | 321S51 | 1.4878 | - | SUS 321H |

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 |
