904L is a low carbon, non-stabilized austenitic stainless steel with high nickel, chromium, and molybdenum content, plus copper addition. It offers superior resistance to strong reducing acids like sulphuric acid, as well as excellent stress corrosion cracking and crevice corrosion resistance. It is non-magnetic and provides good formability and weldability.
