Technical Data Sheet
Alloy 250 (UNS K92890 / Maraging 250) is an age-hardenable iron-nickel steel. Alloy 250 combines ultra-high strength (1800MPa), good toughness, readily machinable in pre-aged condition, excellent transverse properties and resistance to crack propagation. C250 is used for missile and ejector systems, slat tracks and drive shafts.
