The Hardness Detection Method of Quenching Workpiece

Many steel workpieces must be treated with quenching to obtain high hardness, high abrasion resistance, and take into account the appropriate plasticity and appropriate gold phase organization. The hardness of the quenching workpiece is usually detected with the Rockwell hardness tester or superficial Rockwell hardness testers.

The general quenching workpiece uses the Rockwell hardness testers to test HRC. Some quenching thin hard steel plates and some surface quenching workpieces can be used to use the HRA standard.

For the thickness of more than 0.8mm quenching steel plates, the quenching workpiece with a thinner layer and a quenching steel rod with a diameter of less than 5mm can be used to use the superficial Rockwell scales.

iqualitrol portable Rockwell and Superficial Rockwell hardness testers, weighing only 0.7kg, the accuracy is the same as the bench hardness meter. It is very suitable for the hardness testing of medium and small quenching workpieces.

PHR-200 is easy to carry, and the testing process is easy, fast, and non-destructive. It does not require vertical forces, and can read the hardness value directly. It can test the hardness of quenching steel pipes with a thinning of as much as 0.5mm. The inner diameter is greater than 30mm. This instrument can be carried or used on the desk. Using this instrument can test the batch of finished products or semi -finished quenching workpieces.
