Stainless steel mirror panel can be divided into several grades, K8, 12K and so on. Generally, ordinary 2B stainless steel is put into grinding equipment for grinding. Grinding refers to a direct and effective processing method for processing metal surfaces by using mechanical, chemical, and electrochemical principles to obtain smooth and flat surfaces. However, in terms of equipment and technology, the processed stainless steel surface is also classified. This grade refers to the roughness of the stainless steel surface, and the surface varies according to the grade. So how do we distinguish its rank?

First of all, the surface roughness of stainless steel is a watershed between ordinary stainless steel decorative plates and stainless steel mirror panels. If the surface roughness of stainless steel reaches 10 or more, it can be called mirror panel. As can be seen from the figure above, the higher the stainless steel grade, the better the surface effect of stainless steel, and the brighter, smoother and smoother the surface. Differentiate stainless steel grades to understand the purpose of different effects.
Considering that the unit of stainless steel surface roughness is very small, it is difficult to distinguish with the naked eye, and it can only be judged by a special roughness meter. Most of the roughness gauges currently on the market are conventional measuring instruments. Due to the lack of measurement parameters and insufficient measurement accuracy, the measurement results are incorrect, so there is a large loophole in the accuracy of stainless steel mirror panels. Therefore, you should be more careful when purchasing related products.
When stainless steel is delivered from the steel mill, it is in the most primitive state, with almost no processing. The roughness also varies according to the manufacturer's production, and the surface effect is post-processing. Of course, in addition to grinding, there are many surface processes that do not require high surface roughness. For example, embossing, drawing, frosting, etc., the specific requirements depend on the actual requirements of customers.
