Product Detail
Brand: A-one Alloy
Original: 0.00



904L is an austenitic alloy designed  for middle to high level of corrosion resistance. The alloy contains high  levels of chromium and nickel with additions of molybdenum and copper to  provide added corrosion resistance. The high nickel (25%) and molybdenum  (4.5%) contents of 904L provide good resistance to chloride stress corrosion  cracking, general and chloride pitting corrosion resistance above the levels  of 316 and 317 stainless. The copper addition in 904L provides added  resistance to hot phosphoric acid and dilute sulfuric acid.
