Cold Rolled 321 2b Surface Stainless Steel Sheet ASTM A312 321 SS Sheet
Excellent weldability by all standard fusion and resistance methods, both with and without filler metals. Heavy welded sections in Grade 321 require post-weld annealing for maximum corrosion resistance. This is not required for 321.
321 stainless steel is not generally weldable using oxyacetylene welding methods.
321 stainless steel tends to work harden if machined too quickly. For this reason low speeds and constant feed rates are recommended.
321 stainless steel is also easier to machine compared to 321 stainless steel due its lower carbon content.
Hot and Cold Working
321 stainless steel can be hot worked using most common hot working techniques. Optimal hot working temperatures should be in the range 1150-1260°C, and certainly should not be less than 930°C. Post work annealing should be carried out to induce maximum corrosion resistance.
Most common cold working operations such as shearing, drawing and stamping can be performed on 321 stainless steel. Post work annealing should be carried out to remove internal stresses.
Hardening and Work Hardening
321 stainless steel does not harden in response to heat treatments. It can be hardened by cold working, which can also result in increased strength.
