430 stainless steel is a good corrosion resistance of common steel, thermal performance than austenitic good, thermal expansion coefficient than austenitic, heat fatigue, add stabilization element titanium, good mechanical properties of the weld area. 430 stainless steel used in construction decoration, oil burner parts, household appliances, appliance parts. 430F is coupled with easy cutting steel on 430 steel, mainly used for automatic lathes, bolts and nuts. 430LX added steel 430 Ti or Nb, lower C content, improve the processing performance and welding performance, mainly for the hot water tank, hot water systems, sanitary ware, household durable appliances, bicycles flywheel. A chemical composition of carbon (C): ≤0.12% silicon (Si): ≤0.75% manganese (Mn): ≤1.00% phosphorus (P): ≤0.040% sulfur (S): ≤0.030% nickel (Ni): ≤0.60 % (may contain a) Chromium (Cr): 16.00 ~ 18.00% 2 Mechanical Properties Density: 7.75g / cm3 mp: 1427 ℃ expansion coefficient: mm / ℃ (at 20-100 ℃) Young's modulus: kN / mm2 modulus of rigidity Number: kN / mm2 Application Standard: n / a (UNS) 430 stainless steel has the following state, the state is not the same, not the same dirt and corrosion. NO.1,1D, 2D, 2B, N0.4, HL, BA, Mirror, and a variety of other surface processing status. Processing features 1D- granular surface discontinuities, also known as matte. Process: Hot Shot + annealed cold rolled pickling + + annealing and pickling. 2D- was slightly shiny silver white. Process: Hot Shot + annealed cold rolled pickling + + annealing and pickling. 2B- silvery white and than 2D surface gloss and good flatness. Process: Hot Shot + annealed cold rolled pickling + + + temper rolling annealing and pickling. BA- excellent surface gloss, has a high reflectivity, as a mirror surface. Process: Hot Shot + annealing pickling cold rolling + annealing and pickling + + + temper rolling surface polishing. No.3- has good gloss, the surface was coarse grain. Processing: for 2D and polishing products or 2B temper rolling with 100-120 abrasive material (JIS R6002). No.4- better gloss, the surface was fine lines. Processing: for 2D and polishing products or 2B temper rolling with 150-180 abrasive material (JIS R6002). HL- possessed silver gray hair streaks. Processing: 2B product for 2D chemical or polishing the surface of a continuous grinding grain with the appropriate size of the abrasive material. MIRRO- mirror-state process: a 2D goods or goods carried 2B polishing to a mirror effect with the appropriate size of the abrasive material. 430 stainless steel has the ability to corrosion antioxidant properties, but intergranular corrosion tendencies. 430 stainless steel wire is widely used in the axis. Because of safe non-toxic, widely used ingredients utensils.
