Applications
34CrNiMo6 steel is widely used for high-load components including transmission systems, tractor motors, and automotive applications. Common uses include:
- High-load shafts and connecting rod structures
- Surface-hardened wear-resistant components and gears
- Engine camshafts and connecting rods
- Carburized gears, pinions, shafts, bearings, and crankshafts
- Oil drilling equipment and mining components
Heat Treatment Processes
Forging
- Careful preheating required
- Forging temperature: 1150-1200°C
- Maintain temperature above 850°C during forging
Hardening & Tempering
- Heat uniformly to 850°C
- Quench in oil
- Temper at 550°C for minimum 2 hours
- Cool in furnace
Annealing
- Heat thoroughly to 800-850°C
- Slow cool to 550°C
- Complete annealing in air
Normalizing
- Heat to 850°C
- Cool to room temperature in air
