Stainless Steel Foil Alloy 321

Stainless Steel Foil Alloy 321 is an electric-furnace processed austenitic stainless steel. It is not heat treatable and non-magnetic in the annealed state. It contains 18% chromium, 8% nickel, and a substantial addition of titanium. The titanium forms insoluble and stable carbide which ties up all the carbon in the alloy and prevents it from precipitating as chromium carbides. This leaves the chromium in solution to resist the corrosion to a very high degree. This is extremely beneficial in applications of temperatures ranging from 800 to 1500 degrees Fahrenheit. 

Type 321 is commonly used in applications such as manifolds, exhaust stacks and ring collectors
