Properties of AISI 321 Stainless Steel
321 SS Cold Forming
Type 321 is easliy cold formed due to its ductile nature.
321 SS Hot Forming
Type 321 can be readily formed and drawn.
321 SS Machining
Type 321 is less machineable than Type 410 Stainless Steel.
321 SS Welding
Type 321 is easily weldable by all standard techniques. No post weld treatment is required.
321 SS 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.
