Ti is added in the 321 stainless steel as a stable element, so it is better than 316 stainless steel under high temperature. 321 stainless steel owns good wear resistance and corrosion resistance in both organic acids and inorganic acids at different temperature and concentration, especially in oxidizing medium. It is often used to manufacture the line and conveying pipeline of the acid container and wear resistant equipment.
