38CrMoAlA Ultra-Premium Nitriding Alloy Steel Next-Generation Performance for Critical Applications


MATERIAL INNOVATION HIGHLIGHTS

✅ Advanced Nitriding Steel – Proprietary melting process enhances Al/N interaction for superior nitride formation
✅ Extended Service Life – 30-50% longer component lifespan versus standard nitriding steels
✅ Precision Engineered – Specialized manufacturing for high-stress, high-precision applications


MATERIAL PROPERTIES

CHEMICAL COMPOSITION (OPTIMIZED)

Element C Cr Mo Al Micro-Alloys Harmful Elements
Range 0.36-0.39 1.45-1.60 0.18-0.23 1.15-1.25 V≤0.03, Nb≤0.02 [S+P]≤0.015

*Featuring our proprietary "Clean Steel" technology with ultra-low gas content (O≤15ppm, N≤60ppm)*


MECHANICAL PERFORMANCE

After Optimal Heat Treatment:

Property Typical Value Industry Standard Improvement
Rotating Bending Fatigue 580 MPa 450-500 MPa +20-30%
Contact Fatigue Limit 1600 MPa 1200-1400 MPa +25%
Fracture Toughness (KIC) 95 MPa√m 70-80 MPa√m +30%

 Nitriding Performance:

  • Controlled White Layer: 15-20μm (vs typical 25-40μm)

  • Case Depth (500HV): 0.5-0.8mm on demand

  • Surface Hardness: 1000-1250HV (adjustable)


ADVANCED PROCESSING TECHNOLOGY
