904L Stainless Steel - UNS N08904 Super Austenitic Materials


Overview of 904L Stainless Steel

Grade 904L stainless steel is the super austenitic stainless steel with low carbon chemical components.

904L steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The alloy is also resistant to stress corrosion cracking and crevice corrosion.

Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.

Grade 904L contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex 2205 and 2507 stainless steel.
