 430 stainless steel is a good corrosion resistance and general steel, thermal conductivity than austenitic good coefficient of thermal expansion than 

 Austenite is small, thermal fatigue, adding stabilizing elements of titanium, weld parts of the mechanical properties. For architectural use, fuel burner parts, household appliances, household appliances parts .430 F is easy to be added in the 430 steel cutting of steel. For automatic lathes, bolts and nuts, etc. .430 LX 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. 
 Chemical composition 
 430 Stainless Steel Chemical Composition (%) carbon (C): ≤ 0.12 Silicon (Si): ≤ 0.75 Manganese (Mn): ≤ 1.00 phosphorus (P): ≤ 0.040 Sulfur (S): ≤ 0.030 Nickel (Ni): ≤ 0.60 Cr (Cr): 16.00 ~ 18.00 molybdenum (Mo) :2.00-3 .00 430 stainless steel mechanical properties: Density: 7.7g/cm3 Melting Point: 1427 ℃ expansion coefficient: m / m ℃ (at 20-100 ℃) Young's modulus: kN / mm2 modulus of rigidity: kN/mm2 application of standards: n / a (UNS) 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, and various other surface state the surface level of processing characteristics of 2D processing was a little white with a shiny silver pickling hot-rolled + annealed + cold + blasting annealing and pickling 2B was white and silver than the 2D surface gloss and good flatness pickling hot-rolled + annealed + cold + blasting + quenching and rolling annealing and pickling No.3 has excellent gloss, coarse grain products for 2D or 2B with 100 ~ 120 abrasive material (JIS R6002) for polishing and conditioning rolling No.4 has excellent gloss, fine lines on the 2D product or 2B with 150 to 180 abrasive material (JIS R6002) and quenched for polishing silver gray and rolling HL stripe of hair products with 2D or 2B product with the appropriate size of the abrasive material for polishing the surface of continuous grinding grain
