Maraging 250

Maraging 250 steel is a high-strength alloy that offers ultra-high strength and toughness. It provides improved fracture toughness than Maraging 300 steel steel but slightly less strength. The material is relatively soft and 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, including 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 but 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.
