Production according to Standards

AISI 904L   stainless steel is a high alloyed austenitic stainless steel with very low carbon content. The combination of high content 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 acids and inorganic acids, especially chloride crevice corrosion and stress corrosion cracking, is not easy to appear corrosion spots and cracks, and has strong pitting corrosion resistance. AISI 904L has good corrosion resistance in dilute sulfuric acid, and this alloy is a matching steel for the strong corrosive medium of dilute sulfuric acid. 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.
