    Aug 27, 2019 Rockwell hardness (HR) test of carbon steel is carried out when the sample is too small or the Brinell hardness (HB) is greater than 450. The test method is to use a diamond cone with a top angle of 120 degrees or a steel ball with a diameter of 1.5875mm/3.175mm/6.35mm/12.7mm and press it under the surface of the material to be measured

    The B-scale is used for softer materials (such as aluminum, brass, and softer steels). It employs a hardened steel ball as the indenter and a 100kg weight to obtain a value expressed as HRB . The C-scale, for harder materials, uses a diamond cone, known as a Brale indenter and a 150kg weight to obtain a value expressed as HRC

    Feb 01, 2004 Principle of the Rockwell Test. The Rockwell principle is described as follows: An accurately shaped indenter is used to make an indent in the sample to be tested. This indenter is either a spheroconical diamond, a 120-degree cone with a 0.2 millimeter radius tip, or hard metal ball with a 1⁄16, 1⁄8, 1⁄4 or 1⁄2-inch diameter

    For the Brinell test, a 10mm hardened steel ball is used as the indenter; for the Rockwell test, the ball will either be much smaller (usually under 4mm) or will be made from a diamond cone, depending on the specific metal being tested. The Brinell test is meant to measure the width of the indentation on the metal, while the Rockwell test

    Jun 30, 2021 For steels and other comparable materials, the indenter is typically a 10mm hardened steel ball with a force of 3,000 kg. The test varies somewhat depending on whether the material is softer or tougher. After applying stress to the metal, the indenter is withdrawn and the breadth of the resulting indentation is measured with a microscope

    The Rockwell hardness test is the most common method for determining hardness of ferrous and many nonferrous metals. See table below. It differs from Brinell hardness testing in that the hardness is determined by the depth of indentation made by a constant load impressing on an indenter. In this test, a standard minor load is applied to set a hardened steel ball or a diamond cone in the
