Maraging Steels (Ultra-High Strength)
A class of ultra-high-strength steels known for possessing superior strength and toughness without losing malleability.
Maraging Steel: The Pinnacle of Strength
Maraging steels are carbon-free iron-nickel alloys with additions of cobalt, molybdenum, titanium, and aluminum. The term 'maraging' comes from the strengthening mechanism: aging of martensite.
Key Features & Properties
- Strength: Yield strengths up to 2500 MPa (350 ksi).
- Toughness: Exceptional fracture toughness.
- Stability: Minimal dimensional change during heat treatment.
- Weldability: Good weldability for such high strength.
Typical Applications
- Rocket and missile motor cases
- Centrifuge rotors
- High-performance shafts and gears
- Aerospace structural components
Technical Specifications
Maraging steels (e.g., C250, C300, C350) are used in critical applications where failure is not an option and weight must be minimized.
