Stainless Steel: 1Cr17 Standard: GB / T 1220-1992 

 Feature 
 Tensile strength greater than 450, the yield strength of greater than 205, HBS is less than 183 (data for the annealed 
 1Cr17 
 Processing state). Commonly used for architectural decoration, heavy oil burner parts. 430LX added steel in the 430 Ti or Nb, lower C content, to improve the processing performance and welding performance. For hot water tanks, hot water systems, sanitary ware, household durable appliances, bicycles flywheel. 1cr17 stainless steel, steel +12% of the chromium to prevent oxidation caused by natural factors, known as stainless steel, in the JIS code-named 430, so-called 1cr17 stainless steel. But 1cr17 stainless steel can not resist the chemicals in the air caused by oxidation, due to the acidic chemicals in the air more and more, so 1cr17 stainless steel commonly used for some time, there will still be due to non-natural factors oxidation (rust) and situation. 
 Use 
 Good general corrosion resistance of steel. For building decoration, heavy oil burner parts, household appliances and home appliances components. Decorative materials and outdoor advertising billboards; stress corrosion resistance requirements for a product; electronic products, cutlery, bolts, nuts, screen and burner, etc.
