ASTM A240 904L(N08804) stainless steel Possible Alternative Grades

Grade 904L stainless steels are high purity steels with low sulphur content.This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion.
