Maraging C-250 is a 18% nickel, cobalt strengthened steel (C-type), with excellent mechanical properties, workability and heat treatment characteristics.

Applications: Typical applications for maraging include missile and rocket motor cases, landing and takeoff gear, munitions, aerospace, extrusion tooling, die casting, high performance shafting, gears and fasteners.

Material Melt Method: Maraging melt method is a VIM (Vacuum Induction Melt) + VAR (Vacuum Arc Remelt)

Shipped Condition: Maraging is supplied in the annealed and descaled condition. The alloy is very tough, relatively soft (30/34 Rc), therefore, readily machined and formed.

Bar Tolerances: .250” - .499” .500” - .999” 1.000” – 3.625” 3.626” – 6.000” 6.001” – 8.000” 8.001” – 10.000” -.000/+.005 -.000/+.010 -.000/+.031 -.000/+.047 -.000/+.063 -.000/+0.078

Minimum Properties (After Heat Treatment):
  • Hardness - Rc 48
  • Charpy V-notch - 15 ft/lbs
  • Reduction of Area - 50%
  • Elongation - 6.0%
  • Yield Strength - 240 ksi
  • Fracture Toughness - 75 KIC

Physical Properties:
  • Density - 289 lbs./cu.
  • In Average Coefficient of Thermal Expansion (70 – 900 F) - 5.6 x 10 -6 in/in. F

Heat Treatment Aging Process: (Non Die Casting)
Material is to be heat treated to 900 F +/- 10 holding at temperature for 6 hours then cooling at room air temperature. During the aging treatment maraging shrinks uniformly and predictably on all dimensions .0009 in/in

Heat Treatment Aging Process: (Die Casting)
Following the rough machining of the die, anneal at 1500-1525 F for 1 hour per inch of thickness is recommended. After finish machining , an aging heat treatment of 980-1000 F for 6 hours is recommended.

Machining:
Maraging steel in the annealed condition is comparable to 4340. However, when maraging is aged, the type of cutting tool and speeds change. Rigid equipment, firm tool supports, sharp tools and abundant coolant are essential.

Welding:
Maraging is weld able without preheat, in both the annealed and aged condition. Only an aging heat treatment is needed to restore in the weld.

Standards:
  • AMS 6512
  • ASTM A 538
  • Mil-S-46850D
  • UNS K92890
