430 stainless steel plate suppliers
430 stainless steel is a general-purpose steel with good corrosion resistance.It has better thermal conductivity than austenite,a smaller thermal expansion coefficient than austenite, heat fatigue resistance,addition of stabilizing element titanium,and good mechanical properties of the weld. 430 stainless steel is used for building decoration,fuel burner parts, household appliances,and home appliance parts.Because it is safe and non-toxic,it is widely used in food tableware.

Surface grade
430 stainless steel has the following states,the state is different,the dirt resistance and corrosion resistance are also different.
NO.1,1D,2B, No. 4,HL,BA,Mirror,and various other surface treatment states.
1D—The surface has discontinuous granular shape,also called matte surface.Processing technology:hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B—Silver white and better gloss and flatness than 2D surface.Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + tempering rolling.
BA—The surface has excellent gloss and high reflectivity,just like a mirror surface. Processing technology:hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + tempering rolling.
No.4—has good gloss and fine lines on the surface.Processing technology:polishing and tempering rolling of 150~180 abrasive materials (JIS R6002) for 2D or 2B products.
HL—Silver gray with hairline stripes.Processing technology:2D or 2B products are polished with an abrasive material of appropriate granularity to make the surface continuous.
MIRRO—in a mirror state.Processing technology:Grind and polish 2D or 2B products with an abrasive material of appropriate granularity to a mirror effect.
