Stainless Steel 904L Plate / ASTM A240 UNS N08904 Sheet




Grade 904L Plate supplier accordance to ASTM A240/A240M

904l Stainless Steel Plate Supplier

904L gives good resistance to both organic and inorganic acids.The addition of copper in 904L grade gives excellent corrosion resistance against nickel stainless steels, to sulphuric, phosphoric, acetic acids, hydrochloric acids, etc. It also gives a high resistance to pitting in chloride solutions, an excellent resistance to both crevice and stress corrosion cracking
