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

2507 Duplex stainless steel 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 point corrosion, crevice corrosion and uniform corrosion. The biphasic microstructure ensures that the steel has high stress corrosion rupture resistance and high mechanical strength. Applied to oil and gas industry, etc.

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;

444 2B Stainless  Cold Rolled Sheet belongs to high alloy ferritic stainless steel, the steel has good pitting corrosion resistance, crevice corrosion, stress corrosion ability, has good resistance to intergranular corrosion and high temperature oxidation performance. Its high thermal conductivity, very suitable for the use of heat exchange, the plasticity of the steel, good toughness, suitable for stretching, rolling and stamping manufacturing.

2205 2B Stainless Cold Rolled Sheet has yield strength more than double that of ordinary austenitic stainless steel, allowing weight to be reduced when designing products, it has high strength, good impact toughness and good overall and local stress corrosion resistance. Suitable for pressure vessels, high pressure storage tanks, high pressure pipeline, heat exchanger (chemical processing industry), oil and natural gas pipeline.

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).

441 stainless steel has high workability, weldability, corrosion resistance, low carbon content, in addition to the addition of stabilizing element Ti. Generally used as exhaust gum, front tube, CONVERTER, etc., for automobile exhaust system.

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.
