Alloy 321 Heat Resistant Stainless Steel Plate is similar to Type 304 stainless steel, however, it contains a Titanium addition of at least five times the carbon content. This addition is made to reduce or eliminate chromium carbide precipitation - resulting from welding or exposure to high temperatures. Maximum stabilization is accomplished by annealing between 1750° and 1850° F.
321 stainless steel has extensive use in aircraft parts, such as exhaust systems where operating temperatures are higher than 800° F and where corrosive conditions are not too severe; also because of its resistance to scaling and vibration fatigue.
