    UNS S44400 AISI 444 SUS444 Stainless Steel Sheet and Plate For Stainless Steel Tank 444 Inox Sheet

    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.

    FORMS

    Sheet, Coil, Strip, Foil, Ribbon Wire - Profile, Round, Flat, Square


    APPLICATIONS

    Food processing, brewery and wine making equipment, hot-water tanks, heat-exchanger tubing and automotive components

    DESCRIPTION

    Type 444 is a low carbon, low nitrogen, ferritic stainless steel that provides pitting and crevice corrosion resistance superior to most ferritic stainless steels. Applications requiring superior corrosion resistance and resistance to chloride stress corrosion cracking are ideal for this alloy.
