  1. Understanding Steel: The Rockwell Hardness Scale

    The Rockwell Scale is used to determine the hardness of a material, and part C specifically refers to steel. The hardness of a steel is determined by the heat treatment of the blade. In simple terms, the higher the number, the harder the steel. However, one steel is not better than another simply because it is harder.

  2. Rockwell Hardness Testing

    Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentationtste380 rockwell hardness

    The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale. When testing metals, indentation hardness correlates linearly wi

  16. Rockwell Hardness Test - Gordon England

    Rockwell Hardness Test The Rockwell hardness test method consists of indenting the test material with a diamond cone or hardened steel ball indenter. The indenter is forced into the test material under a preliminary minor load F0 (Fig. 1A) usually 10 kgf. When equilibrium has been reached, an indicating device, which follows the movements of the indenter and so responds to changes in depth of penetration of the indenter is set to a datum position.
