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.
