904L Stainless Steel Plate
904L Stainless Steel Plate is a high-alloy super austenitic stainless steel known for its exceptional corrosion resistance. With high percentages of Nickel, Chromium, Molybdenum, and an addition of Copper, it provides superior resistance to strong reducing acids, particularly sulfuric acid. This grade is essential for severe service environments, primarily in the chemical and petrochemical industries (for handling sulfuric and phosphoric acids), pulp and paper mills (bleaching equipment), pollution control (flue gas desulfurization), and applications involving seawater and chloride contamination.
