Portable hardness testers are extensively used in metalworking industries, including foundries, forging shops, and machine shops. They are employed to assess the hardness of metals and alloys, such as steel, aluminum, and titanium. Hardness testing aids in material selection, quality control, and evaluation of heat treatment processes, ensuring .Learn all you need to know about Rockwell hardness testing – including test definitions, test calculations and insight into Rockwell hardness testing machines and HRC hardness testers – with knowledge and expertise from Struers, the world’s leading materialographic and metallographic experts.
Test the hardness of thin and irregularly shaped plastic, rubber, and laminate parts, such as O-rings. These testers can be used on products where the surface area is too small for accurate durometer readings with a standard Shore A tester, such as the rounded surface of O-rings. They include O-ring fixtures that hold five standard-sized O-rings in place during testing.
Starrett Hardness Testers indicate the hardness of a material, usually by measuring the effect on its surface of a localized penetration by a standardized rounded or pointed indenter of diamond, carbide, or hard steel. Hardness is a characteristic of a material, not a fundamental physical property.

4. The indenter for the Rockwell hardness tester C scale is a diamond cone with a 120-degree apex angle. The test load is a fixed value, and the Chinese standard is 150 kilograms of force. The indenter for the Brinell hardness tester is a hardened steel ball (HBS) or a hard alloy ball (HBW). The test load varies with the ball diameter, ranging .Indentation hardness value is obtained by measuring the depth or the area of the indentation using one of over 12 different test methods. Learn more about hardness testing basics here. The Rockwell hardness test method, as defined in ASTM E-18, is the most commonly used hardness test method. You should obtain a copy of this standard, read and .
In the Rockwell hardness test, a differential-depth method, the residual depth of the indent made by the indenter, is measured.In contrast, the size of the indentation is measured in the Brinell, Vickers and Knoop optical test methods.. The deeper a defined indenter penetrates the surface of a specimen with a specified test load, the softer the material that is being tested.Set includes six files and a chart to convert to Vickers scale. It is an economical way to determine the hardness of steel on the Rockwell C-scale.Handles are marked with Rockwell hardness values. If a file can scratch your material, then your material is softer than the file. If a file cannot scratch your material, then your material is harder than the file.
