904L stainless steel alloy, composed of nickel, molybdenum, and copper, is widely known for its superior resistance to strong acids. Furthermore, this grade offers excellent toughness, formability, and weldability and provides high resistance against crevice corrosion and stress corrosion cracking; additionally, copper increases 904L's ability to resist both mild and aggressive environments by acting as an excellent reducing agent.
