904L stainless steel combines molybdenum and copper with iron for tremendously increased resistance to reducing acids like sulphuric acid. It stands up extremely well to chlorides in the environment for low pitting and crevice corrosion, as well as stress corrosion cracking. We can process this steel to fit your applications using our in house processing capabilities and service on your timeline. Grade 904L stainless steel is one of many stainless steel grades that can be purchased at Alpha Overseas.
