430 Classification and process:
1D-surface with discontinuous particles, also known as matte. Processing: hot-rolled + annealed shot peening pickling + cold rolling + annealing pickling.
2D- Slightly shiny silvery white. Processing: hot-rolled + annealed shot peening pickling + cold rolling + annealing pickling.
2B-Glossy and flatness that is silver-white and better than 2D. Processing: hot rolling + annealing + shot peening pickling + cold rolling + annealing + quenching and tempering rolling.
BA-excellent surface gloss, high reflectivity, as the mirror surface. Processing: hot rolling + annealing + shot peening pickling + cold + annealing + pickling + surface finish + temper rolling.
No.3 - has good gloss, the surface was rough. Processing: 2D or 2B with 100 ~ 120 abrasive material (JIS R6002) for polishing and temper rolling.
No.4 - has good gloss, the surface was fine lines. Processing: For the 2D or 2B with 150 to 180 abrasive material (JIS R6002) for polishing and temper rolling.
HL-gray and hairy stripes. Processing: 2D or 2B products with the appropriate size of the abrasive material for polishing the surface was continuous grinding pattern.
MIRRO-Mirror state Processing: 2D or 2B products with the appropriate size of the grinding material for grinding and polishing to the mirror effect.
