WebHardness Scales. There are five major hardness scales: Brinell - HB. Knoop - HK. Rockwell - HR. Shore - HS. Vickers - HV. Each of these scales involve the use of a specifically shaped diamond, carbide or hardened steel indenter pressed into the material with a known force using a defined test procedure. The hardness values are determined … WebJan 1, 2001 · In this research, Finite element analysis (FEA) method is used to simulate the Rockwell hardness measurement process. The influences of spheroconical diamond indenter's geometry, including tip radius, cone angle and form error, on Rockwell C hardness tests are analyzed by the FEA model, and further verified by the experimental …
Rockwell Diamond Indenter With Certification – WESTport Corp.
WebIf a diamond spheroconical indenter is used, then. Rockwell Hardness Number = 100 - (H/0.002) If a ball indenter is used, then. Rockwell Hardness Number = 130 - (H/0.002) Where 'H' is in mm. After the test, the preliminary test force is removed and the indenter is removed from the test specimen. Types of Rockwell Scale WebApr 12, 2024 · If the hardness is higher than this range, Rockwell hardness A scale HRA is used. If the hardness is lower than this range, Rockwell hardness B scale HRB shall be used. The upper limit of cloth hardness HB650 cannot be higher than this value.
