Stainless steel pipes are generally measured by Brinell, Rockwell and Vickers hardness indexes. Among the stainless steel pipe standards, Brinell hardness is the most widely used, and the hardness of the material is often expressed by the indentation diameter, which is both intuitive and convenient. However, it is not suitable for steel pipes of harder or thinner steel.

Stainless steel pipe is a kind of hollow, long and round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transport pipelines and mechanical structural parts. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used to manufacture mechanical parts and engineering structures. It is also commonly used as furniture and kitchenware.
