High-Temperature Applications, Chemical Processing, Food Processing, Automotive
Combines the excellent corrosion resistance of 304 stainless steel with the high temperature resistance of 309 stainless steel. It is more resistant to intergranular corrosion than 304 stainless steel due to its stabilization with titanium.
Overall, 321 stainless steel is valued for its combination of corrosion resistance, heat resistance, and weldability, making it suitable for a variety of high-temperature and corrosive environments.
