430 stainless steel sheet/plate:
Chemical composition of 430 stainless steel coil:
C:≤0.12% Si:≤0.75% Mn:≤1% P:≤0.040% S:≤0.030% Ni:≤0.60% Cr:16 ~ 18%
Surface grade of 430 stainless steel sheet/plate
different state , dirt and corrosion resistance are not the same. NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and other surface treatment.
1)1D:The surface has a discontinuous granular, also known as the fog surface.
Processing: hot rolling + annealing shot blasting pickling + cold rolling + annealing pickling.
2)2D:slightly shiny silver-white
Processing: hot rolling + annealing shot blasting pickling + cold rolling + annealing pickling.
3)2B:Silver white and better than the 2D surface gloss and smooth flatness.
Processing: hot rolling + annealing shot blasting pickling + cold rolling + annealing pickling + quenching and tempering rolling
4)BA:Excellent surface gloss, has a high reflectivity, as the mirror surface
Processing technology: hot rolling + annealing shot blasting pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling
5)N0.3:Has a good gloss, surface was rough lines
Processing: 2D products or 2B with 100~120 (JIS R6002) abrasive material polishing and temper rolling.
6)No.4:Have better gloss, surface is fine lines.
Processing: 2D products or 2B with 150~180 (JIS R6002) abrasive material polishing and temper rolling.
7)HL:Gray hair and stripes.
Processing technology: the 2D or 2B products with the appropriate size of the abrasive material for polishing the surface of a continuous grinding
8)Mirror:In a state of mirror
Processing technology: the 2D or 2B products with the appropriate size of the abrasive material for grinding and polishing to the mirror effect
