444 Stainless Steel Sheet

444 alloy is a low carbon and low nitrogen ferritic stainless steel containing 18% chromium, 2% molybdenum. The alloy is stabilized with additions of columbium and titanium for resistance to intergranular corrosion. One big advantage of the 444 alloy over austenitic stainless steels, such as 304 and 316 alloys, is the practical immunity of the 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 choose for a wide range of applications. Some of the more common applications include heat exchanger tubing, food processing equipment, and hot water tanks.

 

The alloy's resistance to hot corrosion combined with its good creep resistance makes it an excellent choice for automotive exhaust applications.
