Thai customer ordered 904L steel wire from Jfansteel for high voltage discharge electrode spring
904L (UNS N08904) 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
904L alloy is a multi-purpose material, which has been widely used in many industrial fields.Storage and transportation equipment for sulfuric acid, such as heat exchangers;The main parts of flue gas desulfurization device in power plant are: tower body, flue, door plate, inner part, spraying system, etc.Scrubber and fan in organic acid treatment system;Seawater treatment equipment, seawater heat exchanger, paper making industry equipment, sulfuric acid, nitric acid equipment, acid making, pharmaceutical industry and other chemical equipment;Dilute sulfuric acid strongly corrosive medium 904L is matched steel
