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.

321 (UNS S32100) is titanium stabilized austenitic stainless steel plate with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C).
321H (UNS S 32109) stainless steel plate is the higher carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification.
