Steel substrates, pipes, castings, equipment hardness testing averaged across three measurement points.
Equipment type:
Hardness tester machine – HARDNESS TESTER TH160
Exam description:
At the time of testing a steel ball that has been made very hard is pressed into the surface of the piece. The ball creates a circular impression on the surface of the object being examined, the depth of which depends on the hardness of the object. The diameter of the mark is measured and based on this diameter and the pressure exerted the measurement number is looked up on a table, which is noted as HB.
