applicable scope is 20~100 HRB. when the material hardness is under 20HV,on account of the creep of metal the specimen deformation will last for a long time under the test force. The needle on indicator dial or optical projection scale moves slowly, causing difficulty in measuring precision.W...
3.1.5 Rockwell super?cial hardness test—same as the Rockwell hardness test except that smaller preliminary and total test forces are used with a shorter depth scale. 3.1.6 Rockwell hardness number—a number derived from the net increase in the depth of indentation as the force on an indenter...
Completing a hardness test is a critical step in qualifying metal parts. These tests determine metal properties such as wear resistance, toughness, and formability.
The hardness test, for metallurgists, determines the resistance of a metal to penetration by a pyramidal, conical, or spherical indentor. This penetration involves elastic as well as plastic deformation, and the state of stress/strain surrounding the deformation region is a complex one. The hardnes...
