It’s most commonly used to check the hardness of steel that’s been heat treated. Here’s the process: How to Use a Rockwell Testing Machine. . You can’t use the Rockwell method for testing the hardness of .020″ shim stock if it’s supposed to be 60 HRC. Just be aware that there are minimum thicknesses in the 0.040″ and under range .
The hardness of steel is measured in different ways, one of which is the Rockwell Hardness Test. The hardness is based on the composition of the metal as well as heat treatment methods. Grade. Primary Alloying Elements. Characteristics. A36. . *World Steel Association. What Our Customers Say. Determining material hardness by measuring the diameter of the resulting indentations using a carbide ball or hardened steel is known as Brinell hardness test. For example, a ball approximately 10 mm in diameter is pressed into the surface of the material under an applied load commonly equal to 3,000 kgf for steels and 500 kgf for softer .Rockwell Hardness Test. Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load).
