Introduction
430 stainless steel are good corrosion resistance and general steel, better thermal conductivity than austenitic, austenitic smaller than the thermal expansion coefficient, thermal fatigue, adding stabilizing elements of titanium, welding parts of the mechanical properties. For the construction of decorative, oil burner parts, household appliances, household appliances parts .430 F 430 is easy to add cutting of steel on steel. For automatic lathes, bolts and nuts, etc. .430 LX 430 steel in adding 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.

  430 stainless steel are the following state, 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 treatment status.
Processing characteristics of the surface processing level
  2D was slightly shiny silver with a white hot + cold rolling + annealing shot peening + annealing and pickling pickling 2B silvery white and excellent than the 2D surface gloss and flatness pickling hot-rolled + annealed + rolled + shot peening rolling + quenching and 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 rolling quenched
  No.4 has excellent luster, fine lines on the 2D product or 2B with 150 to 180 abrasive material (JIS R6002) for polishing and rolling quenched
  HL was possessed silver hair streaks on the 2D or 2B product with the appropriate product size of abrasive material for polishing the surface of a continuous grinding grain
