2507 2B Stainless Cold Rolled Coils: 2507 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. Due to the high chromium and molybdenum content of the steel, it has excellent resistance to spot corrosion, slot corrosion and uniform corrosion. The biphase microstructure ensures that the steel is highly resistant to stress corrosion cracking and has high mechanical strength.2507 Stainless Steel is used in the oil and gas industry; Offshore stone break day oil platform (heat exchanger tube, water treatment and water supply system, fire system, sprinkler system, water stabilization system; 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 2B Stainless Cold Rolled Coils: Duplex stainless steel 2205 alloy is a duplex stainless steel consisting of 22% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy. 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. 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;

444 2B Stainless Cold Rolled Coils belongs to high alloy ferritic stainless steel, compared with commonly used stainless steel 430 :1. 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. 2. Titanium (Ti), Nb (Nb), zirconium (Zr) and other stabilizing elements are added, so the steel has good intergranular corrosion resistance and high temperature oxidation resistance.

441 2B Stainless Cold 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 2B Stainless Cold 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. Compared with 304 steel, although the elongation is lower (about 30%), the strength and corrosion resistance are comparable, and the corrosion resistance is better than 200 series materials. Main Uses: elevator, escalator decoration board, architectural decoration board, such as decorative structural parts, structural tubes, automobile exhaust system components, washing machine inner cylinder

30409 2B Stainless Cold Rolled Coils, it is 304 high carbon material, digital code for S30409, brand for 07 cr19ni10, carbon content is 0.04-0.1%, it is pressure equipment, mainly used for pressure vessels and other pressure equipment. 30409 stainless steel, carbon content increased to 0.10%, make austenite more stable, in the state of solid solution has good resistance to intergranular corrosion, plasticity, toughness, cold workability, has good bending pipe, welding process performance;

420J2 2B Stainless Cold Rolled Coils has certain wear resistance and corrosion resistance, high hardness, its price is a lower class of stainless steel ball, suitable for the ordinary requirements of stainless steel in the working environment. Suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, etc. Mainly used in the manufacture of air, water vapor, water and oxidizing acid corrosion resistant parts. 420J2 has similar properties and uses as 420J2, but has higher strength and hardness than 420J2 (3cr13).

420J1 2B Stainless Cold Rolled Coils has a certain wear resistance and corrosion resistance, high hardness, its price is low in the stainless steel ball, suitable for stainless steel general requirements of the work environment. 420J1 Stainless steel is suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances and so on. Mainly used in the manufacture of air, water vapor, water and oxidizing acid corrosion resistant parts.

410S 2B Stainless Cold Rolled Coils is a martensitic stainless steel. 410(13Cr) has good corrosion resistance and machining properties, for general purpose steel, cutting tool steel. 410S is a kind of steel that improves the corrosion resistance and formability of 410 steel. 410S stainless steel is suitable for annealing boxes, quenching racks, oxidation resistant partitions and other high temperature devices. It is also used in tower fillers and distillation trays in the petrochemical industry.
