Cold Rolled Stainless Steel Coil (0.2mm-8mm)

  • The 200 series stainless steel was first developed in the United States as a substitute for the 300 series stainless steel during World War II. At that time, due to the war, nickel as a strategic material was strictly controlled by various countries, and the nickel supply in the United States was seriously insufficient.
  • The advantage of 202 stainless steel price is better than 304 stainless steel, most of the 200 series stainless steels sold on the Chinese market have almost no control of sulfur and carbon content in accordance with national standards, and manganese (and nitrogen) has replaced some or all of nickel to produce lower nickel content austenitic stainless steels.
  • The 301 stainless steel is a metastable austenitic stainless steel and has a fully austenitic structure under full solution conditions. Among the stainless steels, 301 is the steel that is most easily deformed by cold deformation.
  • 304 stainless steel is widely used in household products (1,2 tableware), cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical equipment, building materials, chemicals, food industry, agriculture, ship parts.
  • Mainly used for materials other than DDQ applications. This 304 ddq stainless steel material is characterized by relatively low elongation (≧45%), relatively high hardness (≦180HB), and internal grain size grade of 8.0~9.0. Compared with DDQ material, its deep drawing performance is relatively poor.
  • 310 stainless steel (domestic name: 0Cr25Ni20): Austenitic steel with good oxidation resistance, processability and welding performance. Due to high nickel content and relatively stable tissue, it is generally treated by solid solution. High temperature resistance.
  • 316 stainless steel with good welding performance. All standard welding methods can be used for welding. Welding can be used according to the purpose, respectively 316Cb, 316L or 309Cb stainless steel filler rods or welding electrodes.
  • 316ti stainless steel coil is an expensive material, but customers have very high surface quality requirements. The stainless steel sheet inevitably produces various defects during the production process, such as scratches, pitting, sand holes, dark lines, creases, and contamination, so that the surface quality, such as scratches, creases, etc., are high-quality materials. It is not allowed. The pits, holes, and holes are not allowed in spoons, spoons, and forks.
  • the 409L/409 stainless  steel begins to crystallize after pouring, the supercooling degree of the liquid phase is large due to direct contact with the surface of the crystallizer, and at the same time, the surface of the crystallizer promotes non-spontaneous nucleation. Therefore, the nucleation rate of the liquid phase is high and the formation rate is high. Fine equiaxed crystals on the surface. The formation of fine equiaxed grains on the surface is rapid, and the carbides of titanium are too short to precipitate.
  • The advantages of 410s 410 stainless steel High thermal conductivity, small expansion coefficient, good oxidation resistance, excellent resistance to stress corrosion, etc. The application of external refining technology (AOD or VOD) can greatly reduce the gap elements such as carbon and nitrogen.
  • Compare to hot rolled coils, the cold rolled is thinner, so 430 cold rolled coil always be used in Building decoration, fuel burner parts, household appliances, appliances components.
