444 Stainless Steel

UNS S44400

This alloy is a low carbon and low nitrogen ferritic stainless steel that contains 18% chromium and 2% molybdenum. One advantage of Type 444 over austenitic stainless steels, such as 304 and 316 alloys, is the practical immunity of the Type 444 alloy to chloride stress corrosion cracking (SCC). The alloy’s enhanced resistance to pitting and crevice corrosion combined with its good general corrosion resistance to a multitude of environments makes it an excellent choice for a wide range of applications such as heat exchanger tubing, food processing equipment, hot water tanks, and automotive exhaust.
