  The 904L filter cartridge is cut by 904L orifice plate and multi-layer 904L wire mesh sintered or multi-layer 904L wire mesh. It is made by high-precision welding process and can be customized according to different applications and working environment. Excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, good pitting resistance in neutral chloride-containing media, and good resistance Crevice corrosion and stress corrosion resistance. It is suitable for various concentrations of sulfuric acid below 70 °C. It is resistant to any concentration, any temperature of acetic acid under normal pressure, and the corrosion resistance of formic acid and acetic acid. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, especially high resistance to chloride crevice corrosion and stress corrosion cracking, and it is not easy to cause plaque and cracks. The corrosion resistance is slightly better than other steel grades, with good processability and weldability, and can be used in pressure vessels.

  Applications:

  Petroleum, petrochemical equipment, such as reactors in petrochemical equipment.

  Power plant flue gas desulfurization device.

  Seawater treatment equipment, paper industry equipment, sulfuric acid, nitric acid equipment, acid production, pharmaceutical industry and other chemical equipment, pressure vessels, food equipment.

  Pharmaceutical plant reactor.
