M250 maraging grade steel’s strength and malleability in the pre-aged stage allows it to be formed into thinner rocket and missile skins than other steels, reducing weight for a given strength. Maraging steels have very stable properties and, even after overaging due to excessive temperature, only soften slightly. These alloys retain their properties at mildly elevated operating temperatures and have maximum service temperatures of over 400 °C (752 °F). They are suitable for engine components, such as crankshafts and gears, and the firing pins of automatic weapons that cycle from hot to cool repeatedly while under substantial load. Their uniform expansion and easy machinability before aging make maraging steel useful in high-wear components of assembly lines and dies.

Alloy M-250 is an age-hardenable (maraging) iron-nickel steel, combining ultra-high strength, toughness and resistance to crack propagation.
Hardening is accomplished by a simple aging cycle of 3 to 6 hours at 485°C, followed by air cooling. Alloy M-250 provides through hardening without quenching, freedom from decarburization, minimal distortion during aging, good formability, machinability, and weldability and a low coefficient of thermal expansion.
Hardening is accomplished by a simple aging cycle of 3 to 6 hours at 485°C (900°F), followed by air cooling. Alloy 250 provides through hardening without quenching, freedom from decarburization, minimal distortion during aging, good formability, machinability, and weldability and a low coefficient of thermal expansion.
See lessThis grade contains 17–19 wt% nickel, 8–12 wt% cobalt, 3–5 wt% molybdenum and 0.2–1.6 wt% titanium. Addition of chromium produces stainless grades resistant to corrosion.
Due to its unique property i.e. high strength to weight ratio, it is mostly used in rocket casings to give rocket a light but strong casings.
