Drawing Brinell Hardness Testing Machine. A 10mm ball with an applied load of 3 000 kgf is most common for brinell testing. Limitations of hardness testing for deep drawing applications july 29 2020. Vickers cum brinell hardness tester.
It 30 it 30 d it 30 astm auto impact 30 auto impact 40 astm. The load is usually applied for 10 to 15 seconds in the case of testing steel or steel materials and for other softer materials the load must be applied at least 30 seconds.
The brinell hardness meter uses an impulse force of 9 807n to 29420n depending on the test material and the diameter of the impeller ball.
Unlike with rockwell testing brinell tests measure the diameter of the indentation made by the ball not the depth. The brinell hardness test ing uses indenters made of st eel to test materials with hardness values of up to 350 hb or of hard metal tungsten to test materials with har dness values from 350 to. The brinell hardness meter uses an impulse force of 9 807n to 29420n depending on the test material and the diameter of the impeller ball. Relatively high loads are applied to parts via a tungsten carbide ball in this method.
