Welding of Stainless Seamless Pipe

Hardness: Stainless steel pipes are commonly used for measuring Brinell hardness, Rockwell hardness, and Vickers hardness. Brinell hardness is the most widely used standard for stainless steel pipes, and the hardness of materials is often represented by the diameter of the indentation, which is both intuitive and convenient. However, it is not suitable for harder or thinner steel pipes. Rockwell hardness: The Rockwell hardness test for stainless steel pipes is the same as the Brinell hardness test. The difference is that it measures the depth of the indentation. Rockwell hardness testing is a widely used method, with HRC being 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 compensates for the Brinell method. It is simpler than the Brinell method and can directly read the hardness value from the scale of the hardness machine. However, due to its small indentation, the har…
