OVERVIEW
904L STAINLESS STEEL
904L is an austenitic stainless steel. 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 sulfuric 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.
Areas of applications are process equipment in chemical industry, petrochemical industry, bleaching equipment in the pulp and paper industry, flue gas cleaning, desalination, seawater handling, hydrometallurgy, food and beverage, pharmaceuticals and heat exchangers.
