The Rockwell hardness test of stainless steel pipe is the same as the Brinell hardness test, which is an indentation test method. The difference is that it measures the depth of the indentation. Rockwell hardness test is a widely used method, among which HRC is second only to Brinell hardness HB in steel pipe standards. Rockwell hardness can be used to measure metal materials from extremely soft to extremely hard. It makes up for the inadequacy of the Brinell method. It is simpler than the Brinell method and can directly read the hardness value from the dial of the hardness machine. However, due to its small indentation, the hardness value is not as accurate as the Brinell method.
Vickers hardness test of stainless steel pipe is also an indentation test method, which can be used to determine the hardness of very thin metal materials and surface layers. It has the main advantages of Brinell and Rockwell methods, and overcomes their basic shortcomings, but it is not as simple as the Rockwell method, and the Vickers method is rarely used in steel pipe standards.
Stainless steel gas pipes have the advantages of high tensile strength, high ductility and toughness, low coefficient of thermal expansion, strong corrosion resistance, strong wear resistance, long service life, light weight and recyclability.
Stainless steel tube for decorative applications
Stainless steel tube applied to the field of decoration, stainless steel tube because of high tensile strength, good inner wall finish, abrasion resistance and other advantages, so it is widely used in the decoration industry, like our home common stainless steel staircase guardrail handrail, is made of stainless steel decorative control. Many stainless steel pipe manufacturers have also developed a lot of stainless steel decorative pipe color, model, fancy, for the majority of consumers to choose. This shows that stainless steel pipe in the decoration industry by everyone's favorite degree.
