904L is a low-carbon high-alloy austenitic stainless steel containing high nickel and molybdenum content. It provides excellent resistance to uniform corrosion, pitting, crevice corrosion and stress corrosion cracking in harsh acidic and chloride-rich environments. With good ductility, weldability and outstanding resistance to sulfuric acid, phosphoric acid and seawater corrosion, it performs stably in long-term harsh industrial service. It is widely applied in chemical industry, desalination, p

Advantage

1.High nickel and molybdenum composition delivers strong resistance to various acidic media corrosion 2.Excellent pitting and crevice corrosion resistance in chloride and saltwater environments 3.Low carbon content effectively prevents intergranular corrosion after welding 4.Good mechanical stability, ductility and reliable long-term service performance
