12 Gauge Mirror Flat Steel Plate , Stainless Steel Panels ASTM A312 321 Excellent Weldability
Welding
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.
Machining
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.
