Product description

2B refers to the surface of stainless steel, on behalf of the fog, also known as the 2B fog surface, no shadow. The 2B surface of stainless steel is soft, that is, hardness HV (Vickers hardness) at 150-200 degrees. Sorted to 2B face, matte smooth, bright surface, Ba face, 6 K, 8K. BA belongs to the mirror (including BA)


Surface Grading and Process

Surface Rating

2b Stainless steel is only a kind of stainless steel surface treatment status. Stainless steel State is not the same, stain resistance and corrosion resistance is not the same, a total of the following several states:

NO. 1, 1D, 2D, 2B, N0.4, HL, BA, mirror and a variety of other surface treatment status.


Characteristics and Processing Technology

1D-surface has discontinuous granular, also known as fog surface. Processing technology: Hot-rolled + annealing shot pickling + cold rolling + annealing pickling.

2D-is slightly lustrous and silvery white. Processing technology: Hot-rolled + annealing shot pickling + cold rolling + annealing pickling.

2B-is silvery white and has a better gloss and flatness than the 2D surface. Processing technology: Hot rolled + annealing shot pickling + cold rolling + annealing pickling + tempering rolling.

BA-surface gloss is extremely good, has the very high reflectivity, like the mirror surface. Processing technology: Hot rolled + annealing shot pickling + cold rolling + annealing pickling + surface polishing + tempering rolling.

No. 3-Has a good gloss, the surface is coarse-grained. Processing technology: The 2D product or 2B with $number abrasive material (JIS R6002) for polishing and rolling.

No. 4-Has a good gloss, the surface of fine lines. Processing technology: The 2D product or 2B with 150~180 abrasive material (JIS R6002) for polishing and rolling.

HL-is silvery gray and has a hairline stripe. Processing technology: The 2D products or 2B products with appropriate particle size of the abrasive material for polishing to make the surface continuous grinding.

So 2b finish stainless steel sheetis silvery white and has a better gloss and flatness than the 2D surface. Processing technology: Hot rolled + annealing shot pickling + cold rolling + annealing pickling + tempering rolling.
