    Comparative Hardness Scales for Steel Table - Engineers Edge

    Comparison of Hardness Scales: The following table compares the various hardness scales. Assumptions are that the metal tested is homogeneous to a depth several times that of the indentation. To the extent that the metal being tested is not homogeneous, errors are introduced because different loads and different shapes of penetrators meet the

    Hardness may be defined as a material’s resistance to permanent indentation. The durometer scale was defined by Albert F. Shore, who developed a measurement device called a durometer in the 1920s. A chart showing general hardness comparisons is below. Some of HAPCO’s materials are available in both Shore A and Shore D.

    Hardness had a huge impact on scaling of the main equipment of the MVC, equipment cleaning frequency and degree of corrosion were affected by the scaling speed in normal work, so the hardness index of the water was one of the key considerations of MVC. The amount of Ca and Mg elements was measured, and was converted to CaCO 3 for hardness. The Ca and Mg elements concentration in each work

    As you can see from the graphic, there is overlap on the different scales. For example a material with a Shore hardness of 95A is also a Shore 50D. TPEs can range from 10 Shore 00 up to 72 Shore D, spanning all three hardness scales, however, the most commonly used is the Shore A scale. Shore Hardness and How it Relates to Other Properties
