904L stainless steel strip is a low-carbon, high-nickel, molybdenum super austenitic stainless steel strip.
It has good activation-passivation transformation ability and excellent corrosion resistance.
It has good corrosion resistance in non-oxidizing acids, good pitting corrosion resistance in neutral chloride-containing application.
904L stainless steel strip is suitable for sulfuric acid environment with various concentrations below 70 degree.
