Thin 0.8mm Stainless Steel Sheet Coil Grade 444 For Hot Water Tanks

Stainless Steel Sheet Or Coil Grade 444 For Hot-Water Tanks

Strip, Coil, Foil, Wire, ASTM A268, ASTM A240

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.
