Read MoreBall mill is widely used in cement, electric power, mineral processing, building materials, and other industries. As the grinding medium in the ball mill, the grinding ball must have both high wear resistance and good toughness. In recent years, with the rapid development of Chinas industry, the consumption of grinding ball is very large. Jul 11, 2019 Johan August Brinells indentation method and test calculation proved more popular than alternatives (Rockwell, Vickers, etc.) as the BHN can be reliably used to approximate the ultimate tensile strength (UTS) of high-strength steels. What is 300 Brinell Steel? 300 Brinell, as the name suggests, is a steel alloy with a BHN of approximately 300.
