Grade 321 / 321H Stainless Steel Sheet UNS S32100 overview
321 stainless is a titanium stabilized grade commonly used for service in the 1000-1600°F temperature range. For service temperatures up to about 1600°F, a stabilizing treatment at 1550-1650°F, air cool, may be used to provide optimum resistance to intergranular corrosion and to polythionic acid stress corrosion cracking.
321 stainless is readily welded by all common methods including submerged arc. Appropriate weld fillers are AWS ER347 bare wire and E347 covered electrodes. 321 stainless is similar in machinability to 304 stainless steel. It has a machinability rating of 45% relative to AISI B1112.

Possible alternative grades to grade 321 stainless sheets of steel are given Belows
| 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. |
