Properties of AISI 321H Stainless Steel

Type 321 Cold Forming

Type 321 is easliy cold formed due to its ductile nature.

Type 321 Hot Forming

Type 321 can be readily formed and drawn.

Type 321 Machining

Type 321 is less machineable than Type 410 Stainless Steel.

Type 321 Welding

Type 321 is easily weldable by all standard techniques. No post weld treatment is required.

Type 321 Heat Treatment

Type 321 is non-hardenable by heat treatment. 321 is annealed by heating it to 1750 – 2050 °F (954 – 1121°C), then water quench or air cool.
