321 stainless steel coil is a titanium stabilized chromium nickel austenitic stainless steel with corrosion resistance similar to 304/304L. This grade is typically used in the 800-1500藲F temperature range where it is stabilized against chromium carbide precipitation by the addition of titanium, which results in the precipitation of titanium carbides. 321 stainless steel coil has excellent intergranular corrosion resistance after exposure to this temperature range, and this grade resists oxidation up to 1500藲F and has higher creep and stress rupture properties than 304/304L. It also possesses good low temperature toughness and is non-magnetic in the annealed condition.
Chemical Composition (wt%) limits as specified in ASTM A240 and ASME SA240*.
* Maximum, unless range is indicated
Mechanical property requirements for annealed product as specified in ASTM A240 and ASME SA240.
Physical Properties
Physical properties for Type 321 stainless steel
Surface Finish
Alloy 321/H can be easily welded and processed by standard shop fabrication practices.
Hot Forming
Working temperatures of 2100 鈥?2300掳F (1149 鈥?1260掳C) are recommended for forging, upsetting and other hot working processes.
Alloy not suitable for work at temperatures below 1700掳F (927掳C).
Material must be water quenched or fully annealed after working to re-attain maximum corrosion resistance.
Cold Forming
Quite ductile and forms easily.
Readily welded by most standard processes.
Post weld heat treatment is not necessary
Hardening rate of 321 makes it less machinable than 410 stainless steel, but similar to 304
