What Is hairline finish in stainless steel？

There are many kinds of treatment processes for stainless steel surface, and there are 6 common ones, namely mirror surface, sandblasting, chemical, surface coloring, surface drawing and spraying. The brushed stainless steel surface is a common material in daily life.

So what exactly is the stainless steel wire drawing process?

Stainless steel wire drawing is the silk-like texture on the surface of stainless steel, which is just a processing technology of stainless steel. The surface is matte. If you look carefully, there is a trace of texture on it, but you can’t feel it. It is more wear-resistant than ordinary bright stainless steel and looks more upscale.
The wire drawing surface is divided into filament and short filament. The filament is generally ground with a sand stick and has a long linear pattern. Short filaments are generally ground with abrasive belts, with short and chaotic lines. The short filaments are a bit grainy or snowflake-like on the whole, so they are also called snowflake sand.
The values ​​of the stainless steel wire drawing plates are 80, 120, 240, 320, 400, and 800 respectively. The smaller the value, the thicker the wire drawing. Usually, the wire drawing plates we use use 320 wire.
Stainless steel wire drawing board can be divided into dry wire drawing, oil film wire drawing and color wire drawing board. Stainless steel wire drawing board can be used in decoration engineering companies, elevator companies, bathroom factories, decoration companies, large shopping malls, real estate developers, food machinery, pharmaceutical machinery, electronic equipment, etc.
Generally speaking, the wire drawing treatment is to use the abrasive belt (grinding wheel) to grind the object (plate) in a straight line, so that the surface of the halo presents linear wear marks and produces a matt light diffuse reflection effect.

How to make stainless steel have a brushed surface?

Method 1: Manual sanding and polishing. This processing method has high requirements on the technical inspection and control of workers. If the technology is not in place, the ground silk will become different in thickness, which will have a certain impact on the overall beauty.
Method 2: Machine drawing. Because the work is carried out automatically by the machine, the depth and thickness of the wire drawing can be better grasped, and the speed is relatively faster.
Advantages of brushed stainless steel
Wire drawing is usually also called frosting, which means that the surface is polished during the treatment process. The surface is hairline and rough, and it is not easy to be stained with fingerprints during use. In short, it is not dirty.
The effect of light refraction and scattering after drawing is in line with the popular needs of the product, and the rust resistance of ordinary stainless steel is much worse than that of high-quality stainless steel after drawing. The linear grinding makes the surface of the halo appear linear grinding marks, resulting in a matt light diffuse reflection effect.

How to choose stainless steel models for wire drawing?

The choice of material when making brushed stainless steel is very important. At present, there are three specifications of stainless steel sheets on the market: 201 type, 202 type, and 304 type. The quality of these three specifications of stainless steel sheets is the best in the 304 model, the second in the 202 model, and the last in the 201 model.
