High chromium ball quality index
The chromium content of high chromium balls is greater than or equal to 10.0%. The carbon content is between 1.80% and 3.20%. According to national standards, the hardness of high chromium balls must not be less than 58hrc, and the impact value should be greater than or equal to 3.0j/cm2. To achieve this hardness, high chromium balls must be quenched and tempered at high temperature. At present, there are two methods for quenching high chromium balls in China, including oil quenching and wind quenching. If the test hardness of the high chromium ball is lower than 54HRC, it means that it has not been quenched.
