Seamless Steel Hardness Inspection Tool

6.0mm or more in diameter seamless steel pipe, 13mm wall thickness seamless steel pipe material following annealing can be used W-B75-based Webster hardness tester, it tests very fast, easy, seamless steel tubes suitable for rapid non-destructive materials to do qualified test. Seamless steel pipe inner diameter greater than 30mm, wall thickness greater than 1.2mm seamless steel tubes, the use of Rockwell hardness test HRB, HRC hardness. Seamless steel pipe inner diameter greater than 30mm, the seamless steel pipe wall thickness less than 1.2mm, a surface Rockwell hardness tester, hardness testing HRT or HRN. Diameter less than 0mm, more than 4.8mm of seamless steel pipe, using pipe-specific Rockwell hardness test HR15T hardness. When the seamless steel pipe diameter greater than 26mm, you can also use the Rockwell or Rockwell hardness test the surface of carbon steel pipe wall hardness.
