Product Details
Grade 904L Stainless Steel Sheet
904L(1.4539) STAINLESS STEEL
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.
