904L The stainless steel rod
904LGrade is an unstable low-carbon high alloy austenitic stainless steel。Add copper to this level to enhance its resistance to strong reducing acids,Especially the resistance to sulfuric acid is greatly improved。It also has strong resistance to chloride erosion,Including pitting corrosion/Gap corrosion and stress corrosion cracking。
