In Brinell hardness testing, a hard metal ball (carbide ball) is pressed into the material surface to be tested within approximately 10 seconds as the force increases. The applied test force is maintained for 15 to 20 seconds so that the material can settle during this time and the measurement provides reproducible and comparable test results.
Mechanical properties of grinding ball significantly increase after heat treatment After heat treatment of 950 °C * 2 h oil quenching and 350 °C *2 h tempering, grinding ball gets the best comprehensive properties. Compared with cast state, impact toughness and Rockwell hardness are increased by 55% and 26% respectively.

Jun 10, 2019· The Rockwell hardness test was originally created to measure ball bearings. Seven years after Wilber Scoville decided to get serious about the precise measurement of spiciness, a metallurgist working at a New England ball bearing plant invented an accurate and repeatable way to measure hardness.
Feb 16, 2014· We use a 46G wheel for that. With a manual surface grinder I'd rough in .005 away keeping it cool, let the coolant work for you. We take up to .400 a pass with no change in Rockwell. It's all about grinding style/method. I've seen people mess a part (rockwell/cracks/etc) taking off less than .005 while others can do .250 + with no problems.
