Why Choose GCr15 Steel Balls?
GCr15 (equivalent to AISI 52100) is a high-carbon chromium bearing steel that offers exceptional performance characteristics:
- Superior Wear Resistance: The chromium content (1.3-1.6%) enhances hardness and wear characteristics
- High Load Capacity: Excellent compressive strength for heavy-duty applications
- Consistent Hardness: Uniform hardness distribution throughout the material
- Corrosion Resistance: Better oxidation resistance than standard carbon steels
- Thermal Stability: Maintains dimensional stability under varying temperatures
