Product information

Brand: 904L
Standard: ASTM A959
‌ Chemical industry ‌ : 904L stainless steel is particularly widely used in chemical equipment, especially in the processing of highly corrosive media such as sulfuric acid, acetic acid, formic acid and phosphoric acid equipment. Its excellent corrosion resistance ensures the long life and reliability of the equipment when handling various corrosive chemicals.
‌ Oil and Gas industry ‌ : 904L is used in the manufacture of equipment for transporting and handling highly corrosive oil and gas, such as pipes, valves and heat exchangers. Its excellent resistance to pitting and crevice corrosion makes it stable and durable in Marine environments and high salinity environments.
‌ pharmaceutical industry ‌ : In pharmaceutical equipment, 904L stainless steel ensures the hygiene and corrosion resistance of equipment, especially in reactors and storage tanks dealing with strong acids and alkalis. The low carbon content reduces carbide precipitation and improves intergranular corrosion resistance, meeting the pharmaceutical industry's demand for high cleanliness and corrosion resistance.
‌ food industry ‌ : 904L is also widely used in food processing equipment, its corrosion resistance and good processability make it suitable for the manufacture of complex food processing equipment, to ensure the health and safety of products.
‌ Environmental protection equipment ‌ : In the environmental protection equipment, 904L is used to treat the waste water and waste gas containing corrosive chemicals. Its corrosion resistance prolonges the service life of the equipment, reduces the maintenance cost and improves the operation efficiency of the equipment.
