Alloy 904L tubing is a low carbon high alloy austenitic stainless steel, originally developed to resist corrosion in dilute sulfuric acid. Because of the combination of relatively high contents of chromium, nickel, molybdenum and copper, this grade has greatly improved resistance to strong reducing acids, particularly sulfuric acid. Alloy 904L tubing is also extremely resistant to chloride attack from both pittingcrevice corrosion and stress corrosion cracking. Alloy 904L tubing is non-magnetic in all conditions, possesses amazing toughness, and has good formability and weldability.
