UNS N08904 Alloy 904L Coil AISI/ASTM 904L DIN 1.4539 SUS 904L SS2562 thick 0.5mm for petrochemical equipment
904L is an austenitic stainless steel. In comparison to 316L, its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids and in particular its copper addition gives it useful corrosion resistance to all concentrations of sulphuric acid. Its high alloying content also gives it greater resistance to chloride stress corrosion cracking, but it is still susceptible. Its low carbon content makes it resistant to sensitization by welding and which prevents intergranular corrosion.
It has applications in piping systems, pollution control equipment, heat exchangers, and bleaching systems.
Omega experimented with 904L or 'Uranus Steel' with the PloProf dive watches in 1971-72. The inspiration came from French deep sea diving company COMEX, who used this steel in their diving bells due to superior corrosion resistance in salt water
