ASTM A240M SS 904L Plate gives good resistance to both organic and inorganic acids. The addition of copper inASTM A240M SS 904L Plate gives excellent corrosion resistance against nickel stainless steels, to sulphuric, phosphoric, acetic acids, hydrochloric acids, etc. ASTM A240M SS 904L Plate also gives a high resistance to pitting in chloride solutions, an excellent resistance to both crevice and stress corrosion cracking.
