The hardness of steel depends on several factors, such as its composition, manufacturing, and heat-treating processes.The different hardness scales use different loads, different indentor shapes, and different measurements to obtain the hardness number. There are no straightforward formulae to establish relationships between the different scales, making .
Hardness Conversion Formula. Y = aX^2 + bX + c. Where: Y is the hardness value in the target scale; X is the hardness value in the original scale; a, b, and c are constants determined through empirical testing; Example: Converting Brinell (HB) to Rockwell C (HRC) for steels:. HRC = -0.000000567 HB^2 + 0.0624 HB – 13.7. Using this formula, we can convert a Brinell hardness .The STER® Model B-75 Hardness Tester, P/N: B-75, was developed to obtain more a more sensitive response to slight changes in the upper range of hardness covered by the Model B.

A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.Vickers hardness test is a micro testing method used for some specified cases. Sometimes it becomes necessary to change the hardness value from one scale to another. Here we compare the Vickers hardness method with the Rockwell method and their conversion charts.

3. °dH / dGH Or Degrees Of General Hardness °dH are degrees of hardness, also referred to as German degrees (deutsche Härte in the German language). This water hardness unit is based on the mg/L CaO scale (calcium oxide). Specifically, Germans decided that 1°dH should be equal to 10 mg/L CaO, and it kind of stuck. Here is a bit of a comparison:
