UNS N08904, commonly known as 904L with its DIN equivalent W.Nr. 1.4539, is a low carbon super austenitic stainless steel. It has superior corrosion resistance to that of conventional Cr-Ni stainless steels such as SS316L and SS317L resulting from the deliberate addition of copper content. Although the 904L stainless steel has limited use with hydrochloric acids, it has high resistance to pitting corrosion in chloride solutions, high resistance to both crevice and stress-corrosion cracking. The grade is non-magnetic and has excellent formability and weldability, as well as good toughness in cryogenic temperatures. 904L stainless steels have greater resistance to precipitation of ferrite and sigma phases on cooling and welding. The low carbon content reduces the risk of intercrystalline corrosion on cooling or welding processes. This super austenitic stainless steel is widely used in chemical processing, oil & gas, and pharmaceutical industries.
