Product Description

904L super austenitic stainless steel is a low-carbon high-nickel, molybdenum austenitic stainless acid-resistant steel, the introduction of French h s proprietary material. Has a good active - passive transition ability, excellent corrosion resistance. In non-oxidizing acid, such as sulfuric acid, acetic acid, formic acid, phosphoric acid has good corrosion resistance, good resistance to pitting corrosion resistance in chloride ions medium. Also has good resistance to crevice corrosion and stress corrosion resistance. Good corrosion resistance in various concentrations of sulfuric acid below 70?, resistance to any concentration in the atmospheric pressure, any temperature of acetic acid and formic acid and acetic acid mixture.
