Alloy 250 (UNS K92890 / Maraging 250/ DTD 5212) is an age-hardenable iron-nickel steel. Alloy 250 (DTD 5212) combines ultra-high strength (1800MPa), good toughness, readily machinable in pre-aged condition, excellent transverse properties and resistance to crack propagation. Maraging 250 is used for missile and ejector systems, slat tracks and drive shafts.
