321/321H contains titanium to stabilize against chromium carbide formation. This material is also stronger than 304 stainless.The key feature of 321 stainless is its resistance to inter-granular corrosion.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. Type 321 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.
