Surface level
430 stainless steel has the following states, the state is not the same, dirty and corrosion resistance is not the same.
NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states.
Characteristic machining process
1D - The surface has discontinuous granular shape, also known as fog surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D - slightly shiny silvery white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B - silvery white with better gloss and flatness than 2D surfaces. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + tempering rolling.
BA - Excellent surface gloss, high reflectivity, like mirror surface. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + tempered rolling.
No.3 - good gloss, surface is coarse grain. Processing technology: 2D products or 2B with 100~120 grinding materials (JIS R6002) polishing and tempering rolling.
No.4 -- good gloss and fine lines on the surface. Processing technology: 2D products or 2B with 150~180 abrasive material (JIS R6002) polishing and tempering rolling.
HL - silver gray with streaks of hair. Processing technology: the 2D or 2B products are polished with appropriate abrasive materials to make the surface continuous grinding grain.
MIRRO - mirrors. Processing technology: 2D or 2B products with appropriate particle size grinding materials for grinding and polishing to mirror effect.
