Grade 904L stainless steel is a non-stabilized austenitic stainless
steel with low carbon 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
