Which is the best method for hardness testing?
Rockwell Hardness Testing. 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.
Can a hardness test be done on a cylinder?
Performing hardness testing on cylindrical surfaces eg pipes and tubes, the radius of curvature will affect the indentation shape and can lead to errors. It may be necessary to apply a correction factor - this is covered in an ISO specification, ISO 6507 Part 1.
How is hardness measured in a Rockwell test?
The size of the ball will be dependent on the material. For example steel, we will go for the 10mm diameter ball with the applied load of the 3000 kg. In the Rockwell test, we use the depth of the penetration to determine the hardness of the material rather than the surface area to determine the hardness.
How is hardness determined in an indentation test?
More simply put, when using a fixed force (load) and a given indenter, the smaller the indentation, the harder the material. 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.
