What is stainless steel processing and its surface processing grade
Jun 07, 2018

Stainless steel processing is the processing of stainless steel grades to get the desired product.

According to the stainless steel properties, mechanical processing and operations such as cutting, folding, bending and welding are performed to obtain stainless steel products required for industrial production. In this process, some processing equipment such as various machine tools and instruments are used. Stainless steel processing equipment can be divided into shear equipment, Kaiping equipment, slitting equipment and surface treatment equipment, cutting equipment.

 

Surface processing grade of stainless steel processing

 

Original surface: Mainly used for heat treatment and surface pickling after hot rolling of stainless steel, mainly used in chemical plants and industrial tanks.

 

Blunt surface: It is the material after cold rolling heat treatment and pickling, the surface color is silver white, and has a certain degree of luster. Its product use is in deep-drawing processing.

 

Matte: It is the material after cold rolling heat treatment and pickling, and then finish rolling, the main advantage is the smooth surface, easy to grind and other operations. In addition, after surface treatment by improving mechanical properties, it is widely used.

 

Coarse sand: It is obtained by grinding with a grinding belt. The surface gloss is good, but there are discontinuous rough lines. Its main purpose is in building interior and exterior decoration materials, electrical products and kitchen equipment.

 

Fine sand: It is also obtained by grinding with a grinding belt. However, the required grinding belt is higher than that of coarse sand.

 

Wool silk surface: It is used to carry out continuous grinding with appropriate granular polishing belts, and the product surface has a grinding pattern. Its use is for building decoration, elevators and panels.

 

Glossy: First cold rolling, then bright annealing, to get a smooth stainless steel products, the main advantage of this product is excellent surface gloss, high reflectivity, so you can achieve a mirror effect.

 

The surface processing grades of the above seven stainless steel processing are relatively common and commonly used. The grades and properties are sequentially from low to high. Therefore, the corresponding surface processing degree should be selected according to the requirements of product processing and use, and it is expected that Stainless steel surface processing effect.
