In the highly competitive cutting blades industry, it is vital for the blade to have sufficient hardness to retain an edge, while too hard can cause brittle failure. When hardened materials are ground, residual heat may alter the microstructure and soften the blade edge. Testing the hardness of the cutting blades becomes challenging as indents […]
Are you concerned about which Rockwell scale to use for thin materials? Of primary importance in Rockwell scale selection is material thickness. Since the 30 Rockwell scales are distinguished by total test force as well as the indenter type, a load or force that is excessive for a given material thickness will ultimately be influenced […]
Need to produce Brinell hardness values with your Rockwell tester? Hardness conversion makes it possible. Depending on application and availability, different hardness test equipment is used, each presenting their results in a different hardness-scale (e.g., Vickers, Rockwell or Brinell). Too often there is a need to present the hardness results in a different scale than […]
Do you ever wonder how far to space indents when performing Rockwell hardness tests? Indent spacing is a common concern during specimen testing or coupon block verification. Your results can be adversely influenced by spacing indents too close to one another or to the edge of the material. The accepted criteria are that the distance […]
