SUS430 Stainless Steel 
 Stress corrosion resistance is good, typical non-hardening heat treatment of ferritic stainless steel; low thermal expansion, excellent oxidation resistance; 430 stainless steel with good corrosion resistance and general steel, thermal conductivity than austenitic good coefficient of thermal expansion smaller than the austenitic, heat fatigue, adding stabilizing elements of titanium, weld parts of the mechanical properties. 430F (Y1Cr17) ??was added in 430 Easy cutting of steel on steel. For automatic lathes, bolts and nuts, etc. 430 stainless steel has the following states, the state is not the same, dirt and corrosion resistance are not the same. NO.1, 2D, 2B, N0.4, HL, BA, Mirror, surface treatment and various other state .2 D was a little white with a shiny silver pickling hot-rolled + annealed + cold + blasting annealing and pickling than 2B 2D silvery white and gloss and good surface flatness of hot rolled + annealed Shot annealing and pickling pickling + cold + rolled + quenched No.3 has excellent gloss, coarse grain products for 2D or 2B with 100 to 120 abrasive material (JIS R6002) for polishing and conditioning No rolling .4 have excellent luster, fine lines on the 2D product or 2B with 150 to 180 abrasive material (JIS R6002) for polishing and conditioning hair rolling possessed HL silver gray stripe on the 2D product or products with the appropriate grain 2B degree of polishing abrasive grinding the surface of a continuous pattern 
 Use 
 Decorative materials and outdoor advertising billboards; stress corrosion resistance requirements for a product; electronic products, cutlery, bolts, nuts, screen and burner, etc. Decorative pieces used in construction, fuel burner parts, household appliances, household appliances parts. In oxidizing acids, especially nitric acid solution has a good corrosion resistance, is widely used in the manufacture of chemical equipment, nitric acid production, such as absorber, heat exchange device nitric acid, acid tank, pipes and tanks, but also the production of food , wine and other industrial pipes and utensils.

 Mechanical Properties 
 SUS430 (F / FR) stainless steel with the national standard corresponding to the grade of steel is 1Cr17. Tensile strength greater than 450, the yield strength of greater than 205, HBS is less than 183 (data for the annealed 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. 430 stainless steel, steel +12% of the chromium to prevent oxidation caused by natural factors, known as stainless steel, in the JIS code-named 430, is also known as 430 stainless steel. 430 stainless steel, but can not resist the chemicals in the air caused by oxidation, due to the acidic chemicals in the air more and more, so the 430 stainless steel commonly used for some time, there will still be due to non-natural factors oxidation (rust) and situation.
