Maraging 250 is an age hardenable iron-nickel steel alloy melted as VIM + VAR with ultra high strength and toughness. This alloy is easily machinable in the annealed condition prior to final heat treatment. This grade has improved fracture toughness from Maraging 300 but slightly less strength. The unique properties makes it suitable for many critical aerospace applications

Maraging 250 Heat Treatment / Aging:
Maraging alloys are essentially carbon-free, a protective atmosphere is not required during annealing or aging. Material is supplied in the solution annealed condition with a hardness of 30/35 Rc. Typical heat treat time/temperature are listed below. Large cross sections should be aged for longer periods.
NOTE: A modified aging cycle is suggested for die casting applications for increased die life. The following thermal treatments have been used to obtain desirable characteristics for die casters. Following the rough machining of the die, anneal at 1500-1525 ºF for 1 hour per inch of thickness is typical. After finish machining, an aging heat treatment of 980-1000 ºF for 6 hours is typical.
| Temperature | Time | Resulting Hardness |
