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 1800 to 2000 degrees Fahrenheit and and in heat treating and forging applications, 2100-2300 degree’s Fahrenheit.
Type 321 is commonly used in applications such as manifolds, exhaust stacks, and ring collectors.
