2, Advantages
✅ High-Volume Cost Efficiency
Nesting Optimization: AI-driven nesting software reduces material waste by 25% in bulk cutting.
✅ Wear Resistance & Longevity
GCr15’s chromium-carbide network ensures superior anti-pitting and rolling contact fatigue resistance.
✅ Thermal Stability
Through-hardening (Quenched in oil at 830-850°C) guarantees uniform hardness (HRC 60-64) across 20-50mm thickness.
