Martensitic hardened stainless steel balls have remarkable hardness, wear resistance, surface finishing, dimensional tolerances so that it is frequently used in precision devices.
- Material: AISI 420C
- Diameter: 0.5mm-150.00mm;
- Precision Grade：G20,G40,G80,G100,G200, G500, G1000,
- Hardness: HRC57-65
- Application: Precision bearings, anti-friction bearings, conveyor belts and rollers, special valves, couplings, ballpoint pens, etc. They are used for food, medical equipment parts, knotting, oil refining, etc.
- Corrosion resistance: 420C material can resist corrosion when exposed to fresh water, steam, oil, gasoline, and alcohol. However, it will be pitted in a seawater environment, and its corrosion resistance is poor in an acidic environment.
