904L super austenitic stainless steel is a low carbon, high nickel, molybdenum austenitic stainless and acid resistant steel. It is a proprietary material introduced from French h · s company. It has good activation passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid, good pitting corrosion resistance in neutral chloride ion containing medium, and good resistance to crevice corrosion and stress corrosion. It is suitable for various concentrations of sulfuric acid below 70 ℃. It is also resistant to acetic acid of any concentration and temperature under atmospheric pressure and the mixed acid of formic acid and acetic acid.
Application:
*Petroleum and petrochemical equipment, such as reactors in petrochemical equipment.
*Storage and transportation equipment of sulfuric acid, such as heat exchanger, etc.
*The flue gas desulfurization device of power plant is mainly used in the tower body, flue, gate plate, internals, spray system, etc. of the absorption tower.
*Scrubber and fan in organic acid treatment system.
*Seawater treatment plant, seawater heat exchanger, paper industry equipment, sulfuric acid and nitric acid equipment, acid making, pharmaceutical industry and other chemical equipment, pressure vessel and food equipment.
*Pharmaceutical factory: centrifuge, reactor, etc.
*Plant food: soy sauce cans, cooking wine, salt cans, equipment and dressings.
*For dilute sulfuric acid and strong corrosive medium, 904L is the matching steel.
