Alloy 904L/UNS N08904 Pipe
Alloy 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, 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 the 904L stainless steel pipe resistant to sensitization by welding and which prevents intergranular corrosion.
