Knowledge of hardness of stainless steel pipes

Knowledge of hardness of stainless steel pipes

Hardness testing of annealed stainless steel pipes. Materials with an inner diameter greater than 6mm and a wall thickness less than 13mm can use the W-B75 Vickers hardness tester, which is very fast and simple, and is suitable for rapid non-destructive qualification testing of stainless steel pipe materials. Stainless steel pipes with an inner diameter greater than 30 millimeters and a wall thickness greater than 1 or 2 millimeters should be subjected to HRB and HRC hardness testing using a Rockwell hardness tester. For stainless steel pipes with an inner diameter greater than 30 millimeters and a wall thickness less than 1 or 2 millimeters, a surface Rockwell hardness tester should be used to test HRT or HRN hardness. For stainless steel pipes with an inner diameter less than 0 millimeters and greater than 4 or 8 millimeters, a pipeline specific Rockwell hardness tester should be used to test HR15T hardness. When the inner diameter of stainless steel pipes is greater than 26 millimeters, Rockwell or surface Rockwell hardness testers can also be used to test the hardness of the inner walls of the pipes.
