Hot Rolled 3mm Polished Stainless Steel Strip Coil 2B Finish AISI 410 430

400 series stainless steel is a kind of iron, carbon and chromium alloy. This stainless steel has a martensitic structure and iron, and thus has normal magnetic properties. 400 series stainless steel has a strong resistance to high temperature oxidation, and compared with carbon steel, its physical and mechanical properties are further improved. Most 400 series stainless steels can be heat treated.

410: Martensite represents steel grade, high strength, high hardness (magnetic); Poor corrosion resistance, not suitable for use in severe corrosive environment; Low C content, good machinability, can harden the surface by heat treatment.

410L: On the basis of 410 steel, the C content is reduced, its machinability, welding deformation resistance, high temperature oxidation resistance is excellent. Used in mechanical parts, engine exhaust pipe, boiler combustion chamber, burner.

420J1: High hardness and good corrosion resistance after quenching. Applied to tableware (knife), turbine blade.

420J2: Martensite represents steel grade, high strength, high hardness (magnetic); Poor corrosion resistance, poor formability, good wear resistance; Heat treatment to improve mechanical properties. After quenching, the hardness is higher than 420J1 steel. Widely used in processing tools, nozzle, valve, plate ruler, tableware.

430: as a representative ferritic steel, thermal expansion rate, formability and oxidation resistance. Suitable for heat resistant appliances, burners, household appliances, 2 class tableware, kitchen sink. Low price, good processing is the ideal SUS304 substitute; Good corrosion resistance, typical non heat treatment hardening ferritic system stainless steel.

Most 400 series stainless steels can be heat treated.

The commonly used 400 series of stainless steel varieties are 430 type containing 18% chromium and 410 type and 420 type containing 13% chromium stainless steel models, 430 type stainless steel model use the largest. 430 stainless steel model is characterized by cheap price, small thermal expansion coefficient, chloride stress corrosion resistance is better than 300 series of stainless steel varieties; However, its shortcoming is that the formability, weldability and tensile strength is less than 304 stainless steel model, therefore, its use field is limited. In the same chromium content, such as in the atmosphere, fresh water and nitric acid so oxidizing medium, 400 series of stainless steel corrosion resistance and 300 series of stainless steel varieties are the same, and usually 400 series of stainless steel varieties corrosion resistance is better than 200 series of stainless steel varieties. The 400 series stainless steel variety currently adds trace niobium, titanium, copper and aluminum elements to improve its deep drawing performance, weldability, corrosion resistance and high temperature strength, and can partially replace the 304 stainless steel model. At present, the 400 series stainless steel varieties with the above trace elements are SUS430LX, 430JIL, 444, 445M2, NSS447M1 and so on.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.

The group company mainly produces and sells a series of steel products such as steel pipe, steel coil, steel plate, copper pipe, copper plate, copper strip, aluminum pipe, aluminum plate, galvanized steel pipe, galvanized coil, galvanized plate and so on.The group company has established five platforms, including three production plants and two processing plants. At present, it is still expanding its production line, basically forming a development model of integration of production, processing and sales.

Our annual production capacity of various specifications is about 1 million metric tons. In addition to being a supplier of our series of products, the group company is also committed to expanding its commitment to customers by strengthening services and adding new facilities.
