High chromium balls are called high chromium balls if their chromium content and carbon content are between The ball must adopt high temperature quenching + tempering treatment (currently, there are two quenching methods for domestic high chromium ball quenching: oil quenching and air quenching). If the detected hardness () is lower than the following, it means that the high chromium ball has not been quenched. , The quality index of medium chromium balls contains chromium content of 3.~., and carbon content is called medium chromium balls. The impact value is ./cm. The national standard requires that the hardness of medium chromium balls () must be above. In order to ensure the steel In terms of ball quality, chromium balls need to be treated with high temperature tempering (in order to eliminate casting stress). If the surface of the steel ball is dark red, it indicates that the product has been tempered at high temperature. If the surface of the steel ball is still metallic, it indicates that the product has not been tempered by high temperature. Fire treatment.
