Technical Specifications
- Size Range:
- Inner Diameter: 30mm to 300mm
- Thickness: 20mm, 25mm, 30mm, 40mm, 50mm (Customizable)
- Batch Capacity: 10,000+ units/month with 15-day lead time
- Standards Compliance: ISO 683-17, ASTM A295, DIN 17230
Advantages
- High-Volume Cost Efficiency: 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
Manufacturing Process
| Process Stage | Technical Content |
|---|---|
| Blank Preparation | GCr15 steel plates laser-sliced to near-net thickness |
| Batch Cutting | Multi-head waterjet/laser cuts 50+ rings per cycle |
| Heat Treatment | Vacuum quenching + cryogenic tempering (-70℃) |
| Precision Grinding | CNC centerless grinding for ID/OD finishing (±0.05mm) |
| Quality Assurance | 100% hardness mapping (Rockwell C) + ultrasonic flaw detection |
