Technical Data

Technical parameters of Rockwell hardness

 Rockwell hardness test force

 ->  Preliminary test force (Tolerance: ± 2.0%): 98.07N (10kg)                

  ->  Total test force (Tolerance: ± 1.0%): 588.4N (60kg), 980.7N (100kg) 1471N (150kg)

◆ indenter: Diamond cone indenter, Ф1.5875mm ball indenter

Metallic materials testing applications, the most commonly used scale is A, B, C.

In conformity with the above principles should be preferred.

C scale indenter is 120 ° diamond cone total test force of 1471 Newtons 150 kg force, for the determination of heat-treated steel products

A scale indenter is 120 ° diamond cone total test force is 588.4 Newton 60 kg force, for the determination of hardness exceeding 70HRC metals such as tungsten carbide, etc. can also be used to determine the hard sheet material and a thin surface layer hardness.

B 1.588 scale indenter ball diameter of 980.7 total test force Newton 100 kg force, for the determination of soft or medium hardness of the metal and non-hardened steel products.

It should be based on the type of sample material or estimates select the appropriate hardness scale of hardness measurements. Beyond the corresponding measuring scale measurement range can cause reduced accuracy or damaged head.
