Maraging 250 (AMS6512)

Maraging 250 steel bars are a cobalt-molybdenum steel that offer ultra-high strength.

---

Maraging 250 steel is a high-strength alloy that offers ultra-high strength and toughness. The alloy provides improved fracture toughness than Maraging 300 steel but slightly less strength. The material is relatively soft and is easily machined and formed. The alloy is produced by vacuum induction melting and vacuum arc remelting (VIM + VAR). We supply Maraging 250 in the annealed condition where the microstructure consists of fine martensite. Very high tensile strength is achievable after heat treatment and precipitation hardening.

Suitability

The alloy is suitable for critical applications and highly stressed parts and include engine components, aircraft landing gear and crankshafts. Maraging 250 is readily weldable and provides good notch impact toughness at temperatures below - 50°C.

Machinability

Maraging steels are typically machined in the annealed condition, although they may also be machined in the maraged condition. The low-temperature maraging treatment minimises distortion, allowing machining to close tolerances. The maraging treatment results in a product with good dimensional stability.
