Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel 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.
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 stainless steel 2205.

UNS N08904 also know as 904L falls in the austenitic stainless steel group. It has high molybdenum and extremely low carbon content .Copper content in the alloy greatly improves resistance to strong reducing acids, especially (H2SO4) sulphuric acid.904L has better resistance ti chloride attack against both stress corrosion cracking and crevice / pitting corrosion .
With excellent weldability and formability 904L also maintain non-magnetic state in all conditions.904L provides excellent toughness , even down to cryogenic temperatures with its austenitic structure.
