321 is titanium stabilized chromium-nickel austenitic stainless. With similar corrosion resistance properties to that of 304/304L. 321 is used typically in environments with 800-1500°F temperature range, this is because the alloy is stabilized through the addition of titanium to protect against Chromium carbide forming. 321 has superior intergranular corrosion resistance after being exposed to these temperatures.
Common industry/applications are: Aerospace, Chemical Processing, Food Processing, and Oil and Gas
Product forms include round bar, plate & sheet, and forgings.
