Stainless steel seamless pipes are made by putting ordinary stainless steel decorative plates into grinding equipment for grinding. Grinding refers to a direct and effective machining method that uses mechanical, chemical, electrochemical and other principles to process metal surfaces to obtain a smooth surface. However, in terms of equipment and technology, the stainless steel surface is also graded. The grade refers to the roughness of the stainless steel surface, which varies with grade.

The surface roughness of stainless steel is the watershed between ordinary stainless steel decorative panels and seamless steel pipes. If the surface roughness of stainless steel reaches level 10 or higher, it can be called a mirror panel. The higher the grade of stainless steel, the better the surface effect of stainless steel, the smoother and smoother the surface, and the easier it is to distinguish the grade of stainless steel. 

So, how to distinguish the grade of seamless steel pipe?
Considering that the surface roughness unit of stainless steel is very small, it is difficult to distinguish with the naked eye, so it can only be judged with a special roughness meter. Most roughness meters currently on the market are conventional measuring instruments. Due to lack of measurement parameters and insufficient measurement accuracy, the measurement results are incorrect. Therefore, there are big loopholes in the accuracy of seamless steel pipes. Therefore, please pay more attention when purchasing related products.
When the seamless tube stainless steel leaves the factory, it is in its original state, with almost no treatment. The production of seamless steel pipe manufacturers varies, and the surface effect is post-processed. Of course, in addition to grinding, there are many surface finishes that do not require high surface roughness. For example, embossing, drawing, frosting, etc., the specific requirements depend on the actual requirements of customers.
