The hardness of the steel ball is determined by the ball made of different materials. Common ball with stainless steel ball, bearing steel ball, carbon steel ball, as well as carbide ball. What factors led to the ball of different materials have different hardness?
The hardness of steel ball directly by heat treatment process, that is, the impact of quenching and tempering. In the heat treatment process, bearing steel balls after quenching and tempering, the internal microstructure changes, resulting in hardness has also changed. However, the stainless steel ball can not be heat treatment process, as stainless steel is austenitic steel, their own conditions can not be limited heat treatment process.
