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.
