Rockwell hardness testing provides a fast and reliable method for determining the hardness of metallic and non-metallic materials. We perform measurements using the appropriate Rockwell scales for ferrous metals, non-ferrous metals, and plastics, including superficial Rockwell hardness testing for thin specimens, small test areas, and materials with varying hardness in the surface layer.
Method
Rockwell hardness testing is a fast and reliable method widely used in manufacturing and laboratory practice, particularly for metallic materials. It is applied for quality control of heat-treated metals, incoming material inspection, weld evaluation, hardness verification of plastics, and failure analysis. Hardness is determined by measuring the depth of an indentation produced by a diamond indenter or a tungsten carbide ball. Due to the relatively high test loads involved, the method is particularly suitable for larger specimens and can also be used for specialized tests, such as the Jominy (End Quench) test.
Typical applications:
- Quality control of heat-treated metals
- Incoming material inspection
- Weld evaluation of steels and other alloys
- Hardness verification of rigid plastics
- Failure analysis
Key features of Rockwell hardness testing:
- Particularly suitable for larger specimens
- Does not require optical measurement of the indentation
- Can be used for advanced testing applications
- Performed in accordance with ASTM E18, ISO 6508, and JIS Z 2245 standards
Equipment
Rockwell hardness testers and related accessories are available for both laboratory applications and demanding industrial environments, including high-volume production facilities.
