904L/N08904/1.4539 Pipe and Tube

Characteristic: 904L is an austenitic alloy designed for a 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 provides added resistance to hot phosphoric acid and dilute sulfuric acid.
