Premium AISI 904L Stainless Steel Factory - High-Quality UNS N08904 Steel

AISI 904L stainless steel is a high alloy austenitic stainless steel with very low carbon content. The combination of high levels of chromium, nickel, molybdenum and copper gives the steel good resistance to uniform corrosion. The addition of copper makes it have strong acid resistance, can resist various organic and inorganic acids, especially chloride crevice corrosion and stress corrosion cracking, is not easy to appear corrosion spots and cracks, and has strong resistance to pitting corrosion. Nitrogen (N) can reduce the precipitation rate of chromium carbide, thereby reducing the sensitivity of sensitization, and can also improve the resistance to chloride pitting and crevice corrosion. This alloy is the supporting steel for the strong corrosive medium of dilute sulfuric acid. In addition, it is also resistant to seawater, has good machinability and weldability, and is widely used in construction, chemical, medical and other industries. AISI 904L stainless steel is often used in reactors in petroleum and petrochemical equipment; sulfuric acid storage and transportation equipment, such as heat exchangers; power plant flue gas desulfurization devices, such as tower bodies, flues, shutters, internals, spray Washers and fans in organic acid treatment systems; seawater treatment devices, such as seawater heat exchangers; paper industry equipment, sulfuric acid, nitric acid equipment; acid production, pharmaceutical industry and other chemical equipment, pressure vessels, food equipment.
