904L

 


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.



Available Product Forms: 
Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire
