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.

3, Manufacturing Process

Process Stage Technical Content
1. Blank Preparation GCr15 steel plates laser-sliced to near-net thickness.
2. Batch Cutting Multi-head waterjet/laser cuts 50+ rings per cycle.
3. Heat Treatment Vacuum quenching + cryogenic tempering (-70℃).
4. Precision Grinding CNC centerless grinding for ID/OD finishing (±0.05mm).
5. Quality Assurance 100% hardness mapping (Rockwell C) + ultrasonic flaw detection.

4, Applications

Automotive: Transmission bearings, wheel hub units.

Wind Energy: Main shaft bearings, pitch/yaw systems.

Heavy Machinery: Mining conveyor rollers, crane slewing rings.

Railway: Axlebox bearings, traction motor assemblies.

5, Certifications & Compliance

IATF 16949 (Automotive), ISO 14001 (Environmental), EN 10204-3.1 Material Certificates.

RoHS/REACH compliant (Hexavalent chromium-free passivation).

CNC无中心磨削的ID/OD饰面(±0.05mm).
