Chrome Steel Balls
Profile:Chromium steel balls are precision steel balls made from high-carbon chromium steel, with a surface hardness of HRC60-66 after heat treatment. They have high strength, wear resistance, and corrosion resistance, and are widely used in bearings, valves, precision instruments, and other equipment, serving as key transmission and load-bearing components in the industrial field.
Hardness:HRC60—66
Hardness:HRC60-66
Sizes:1/32 inch (0.8 mm) to 13/16 inch (20.637 mm) (also can be customized according to your requirements)
Grade:G10,G20,G24,G28,G40,G60,G100,G200
Applications:Chromium steel balls are used in high-precision bearings, automotive parts, machine tool spindles, and the rotating parts of motors. They have high hardness (HRC60-66), wear resistance, and fatigue resistance, ensuring stability and long life under high-speed operation. They are also used in precision instruments, aerospace, and rail transit fields, adapting to harsh working conditions with high loads and speeds.
