300M ALLOY STEEL (4340M)
300M steel is a vacuum melted low alloy steel with the inclusion of vanadium and a higher silicon composition. It has a very good fatigue strength and resilience. Where fracture toughness and impact strength are crucial, 300M is a great choice.
APPLICATIONS:
- Aircraft Landing Gear
- Airframe Parts
- Missile Components
- Motorsport Applications
