Several state of 430 stainless steel of magnetic

430 stainless steel magnetic has the following kinds of state, 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.
Surface processing  430 stainless steel magnetic  feature processing technology
2D is a shiny silver white hot shot peening + annealing pickling + cold + annealing and pickling 2B is silver white and better than 2D surface gloss and flatness of hot rolling + annealing pickling + cold + shot peening annealing and pickling + temper rolling

No.3 has a 430 stainless steel plate  gloss, coarse grain of 2D or 2B with 100~120 (JIS R6002) abrasive polishing and temper rolling
No.4 has a good gloss, fine lines on the 2D or 2B with 150~180 (JIS R6002) abrasive polishing and temper rolling
430 stainless steel magneticHL was abrasive material and hair gray stripes on 2D or 2B with the proper size of polishing the surface is continuous grinding grain
