High-Performance 904L Super Austenitic Stainless Steel Coils
Engineered for extreme environments. Superior resistance to sulfuric, phosphoric, and acetic acids.
Directly from China’s leading high-nickel alloy specialist.
Procurement officers for 904L need to see the "Super" chemistry (High Ni/Mo/Cu).
Acid Resistance: Specially developed to withstand dilute sulfuric acid where 316L fails.
Pitting & Crevice Protection: High Molybdenum content ensures stability in high-chloride/seawater conditions.
Non-Magnetic: Remains non-magnetic in all conditions, perfect for specialized electronics and medical equipment.
Copper Addition: The unique addition of Copper provides excellent resistance to strong reducing acids.
Chemical Processing: Production of phosphoric and sulfuric acids; heat exchangers.
Oil & Gas: Offshore piping, scrubbers, and subsea equipment.
Pulp & Paper: Bleaching equipment and pressure vessels.
Environmental: Flue-gas desulfurization (FGD) systems.
Verified Chemical Balance: We provide detailed lab reports confirming the specific levels of Nickel, Molybdenum, and Copper.
Surface Integrity: We use specialized PVC protection to ensure zero scratches on BA or 2B surfaces.
Secure Logistics: Heavy-duty seaworthy packaging designed for high-value alloy transport.
