904L is an austenitic stainless steel designed for moderate to high corrosion resistance. Its low carbon content improves cleanliness and weld strength.
904L is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.
FOllowing is melting methods of 904L forged parts
Material shall be produced by a triple melt process consisting of vacuum induction melting (VIM)followed by electroslag consumable electrode remelting (ESR)and vacuum arc consumable electrode remelting VAR).
