Carbon steel ball classification:

1. According to the material, it is divided into low carbon steel ball, medium carbon steel ball, high carbon steel ball, the main material is 1010/1015, 1045, 1065/1085, etc.;

2. According to the hardness, it is divided into soft balls and hard balls, which is to judge whether heat treatment is required: the hardness after heat treatment increases, about HRC60, commonly known as hard balls; the hardness without heat treatment is relatively low, about HRC26. Commonly known as soft bright ball;
