Type 321 can be cold rolled to various tempers. Contact Ulbrich Technical Services for additional information.
ADDITIONAL PROPERTIES
CORROSION RESISTANCE
Type 321 has excellent corrosion resistance equivalent to type 302 or 304 in the annealed condition and superior if a weldment in these grades has not been post-weld annealed or if the application involves service in the 800 °F - 1600 °F range.
Chemical Composition of Stainless Steel 321 Coil
Grade | C | Mn | Si | P | S | Cr | Mo | Ni | N | Other | |
321 | min. max | – 0.08 | 2.00 | 0.75 | 0.045 | 0.030 | 17.0 19.0 | – | 9.0 12.0 | 0.10 | Ti=5(C+N) 0.70 |
PROCESSING:
Type 321 is non-hardenable by heat treatment. Annealing: Heat to 1750 – 2050°F, then water quench or air cool. Forming: Type 321 can be readily formed and drawn. Like most austenitic stainless steels, Type 321 work hardens and may require annealing after severe forming.
