430 Stainless steel coil manufacturer
430 stainless steel is a general steel with good corrosion resistance. Its thermal conductivity is better than austenite, its thermal expansion coefficient is smaller than austenite, its heat resistance fatigue, and the addition of stabilized element titanium has good mechanical properties at the welding seam.
430 stainless steel for building decoration, fuel burner parts, household appliances, home appliances parts.

430 Characteristic machining technology
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 - A slightly silvery white colour.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B -- Silver white with better gloss and flatness than a 2D surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
Ba - Excellent surface gloss, high reflectivity, like a mirror surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.
No.3 -- Good gloss, coarse grain surface.
Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).
No.4 -- Good gloss, fine lines on the surface.
Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).
HL -- Silver grey with hair streaks.
Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.
MIRRO -- Specular.
Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
