Stainless Steel: 1Cr17
  Standard: GB / T 1220-1992
Features:
Tensile strength greater than 450, the yield strength of greater than 205, HBS is less than 183 (data processing for the annealed state 1Cr17). Commonly used for architectural decoration, heavy oil burner parts. 430LX add steel in the 430 Ti or Nb, lower C content, improve the processing performance and welding performance. For the hot water tank, hot water systems, sanitary ware, household durable appliances, bicycles flywheel. 1cr17 stainless steel, chrome steel, more than +12% to prevent oxidation caused by natural factors, called [1] Stainless steel, 430 in the JIS code number, so-called 1cr17 stainless steel. But 1cr17 stainless steel can not resist the chemicals in the air caused by oxidation, due to chemicals in the air more and more acidic, so 1cr17 stainless steel commonly used for some time, due to non-natural factors will have oxidation (rust) and situation.
Uses:
Good general corrosion resistance of steel. For building decoration, heavy oil burner parts, home appliances and appliances components. Decorative material and outdoor advertising billboards; stress corrosion resistance requirements for a product; electronic products, cutlery, bolts, nuts, screen and burner and so on.
