The first digit is Y, which is the first letter of tungsten carbide in Chinese pronunciation. The second digit refers to the nominal diameter of tungsten carbide ball (mm), usually ignored. The third digit is the tolerance class code of tungsten carbide ball, usually adds letter G in front of tungsten carbide ball tolerance class to consist of tolerance level code, such as G3, G5, G10, G16, G20, G100 and so on. The next digit is the deviation of the batch diameter or b mark (means it does not supplied by the variation of the batch diameter), the average deviation of the diameter uses plus or minus and number to present (μm), and it is also usually ignored. At last, it is the standard number of tungsten carbide ball and the complementary technical conditions.
