904L NO.1 Stainless Hot Rolled Coils has good activation-passivation conversion ability and excellent corrosion resistance. It has good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid and phosphoric acid, good pitting resistance in neutral chloride ion medium, and good crevice corrosion resistance and stress corrosion resistance. Application: petroleum, petrochemical equipment, such as petrochemical equipment reactor, etc.

2507 NO.1 Stainless Hot Rolled Coils is a ferritic-austenitic (two-phase) stainless steel with excellent resistance to point corrosion, slot corrosion and uniform corrosion. It combines many of the most beneficial properties of ferritic and austenitic steels. Mainly used for petrochemical equipment; Desalination (desalination) equipment (and equipment in the high pressure pipe, sea water pipe); Mechanical and structural components that require both high strength and high corrosion resistance; Fuel (waste) gas purification equipment.

2205 NO.1 Stainless Hot Rolled Coils is a duplex stainless steel consisting of 22% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance. The yield strength of 2205 duplex stainless steel is more than double that of regular austenitic stainless steel, which allows designers to design products with reduced weight and gives this alloy a price advantage over 316,317L. Applications: Pressure vessels, high-pressure storage tanks, high-pressure pipelines, heat exchangers (chemical processing industry); Oil and gas pipeline, heat exchanger pipe fittings; Sewage treatment system; Pulp and paper industry classifiers, bleaching equipment, storage and treatment systems; Rotary shaft, press roller, blade, impeller, etc., in high strength corrosion resistant environment; The cargo container of a ship or truck; Food processing equipment

444 NO.1 Stainless Hot Rolled Coils is a kind of ultra-low carbon nitrogen, containing 18% chromium and 2% molybdenum, high corrosion resistance of ferritic stainless steel.   The steel is usually stabilized by niobium or titanium, which can avoid intergranular corrosion after welding.   The steel is especially suitable for use in various water treatment devices.   The yield strength of 444 stainless steel is 1.5 times that of carbon steel and 6 times that of glass steel. It is excellent for shock resistance, snow resistance, wind pressure resistance and impact resistance.  The chromium content is about 1.0%, and the alloying element molybdenum (Mo) is added, so the steel has good pitting corrosion resistance, crevice corrosion, stress corrosion resistance, and its corrosion resistance is even better than SUS304 and SUS316 in some fields.

441 NO.1 Stainless Hot Rolled Coils has very low C, N, adding Ti and Nb, improve the material's high temperature strength, corrosion resistance, weldability and workability. Features: high temperature corrosion resistance; Weldability; High temperature strength; Magnetic; Scope of application: exhaust manifold, front pipe of automobile exhaust system, etc

439 NO.1 Stainless Hot Rolled Coils is on the basis of ordinary ferritic material (430) to reduce the content of C, at the same time adding Ti and other stabilizing elements, so that the steel resistance to intergranular corrosion, formability and weldability have been improved. Main Uses: elevator, escalator decoration board, architectural decoration board, such as decorative structural parts, structural tubes, automobile exhaust system components, washing machine inner cylinder.
