What Is Stainless Steel Strip Surface?

Stainless steel strip surface is one of the major factor before placing order. If you are the beginner of this area, you can benefit from this news.


No. 1 surface refers to the surface obtained by heat treatment and pickling after hot rolling of the stainless steel strip.

It is to remove the black oxide scale produced during hot rolling and heat treatment by pickling or similar treatment methods.

This is No. 1 surface processing. The No.1 surface is silvery white and matt.

The surface of 2B is different from the 2D surface in that it is smoothed with a smooth roller, so it is brighter than the 2D surface.

The surface roughness Ra value measured by the instrument is 0.1~0.5μm, which is the most common processing type.

This kind of stainless steel strip surface is the most versatile, suitable for general purposes.

Mechanical polishing type is a polishing method that relies on cutting and plastic deformation of the material surface to remove the polished convexities to obtain a smooth surface of polished stainless steel strip.

Generally, oil stone sticks, wool wheels and sandpaper are chose with manual operations.

The surface of No. 4 is a fine polished surface finish that is brighter than the surface of No. 3.

It is also obtained by polishing the stainless steel cold-rolled stainless steel plate with 2 D or 2 B surface as the base and polishing with abrasive belt with a grain size of 150-180# Machined surface.

BA is the surface obtained by bright heat treatment after cold rolling.

Bright heat treatment is annealing under a protective atmosphere that guarantees that the surface is not oxidized to preserve the gloss of the cold-rolled surface, and then use a high-precision smoothing roll for light leveling to improve the surface brightness.


Buyers can choose the corresponding surface finish according to their own usage of stainless steel strips.
