Maraging Steel - Vascomax

MARAGING / VASCOMAX / MDN STEEL

Stronger Steel - Higher Quality - Minimum Distortion
Maraging Steel is an iron-based steel alloyed with 18% nickel and 7 to 12% cobalt as a strengthening agent. Essentially carbon-free, other alloying elements include moly, aluminum and titanium. This combination creates a superior steel that:

Meets AMS 6512.
Meets AMS 6514.
Meets MIL-S-46850.
Maintains high strength and toughness.
Allows close machining with minimal distortion.
Has uniform, predictable shrinkage during heat treatment.
Can be nitrided easily.
Resists corrosion and crack propagation.
Has a high level of cleanliness and excellent polish ability.
Remains readily weldable.

Maraging (Vascomax) in Aerospace
Maraging (Vascomax) is stronger than most standard steel yet still malleable. It can be flow formed over mandrels as a thinner rocket or missile skin at any length. Thinner means more room for payloads and fuel.

Maraging for the Military
Our armed forces rely on weapons that perform reliably over long periods in harsh environments. Maraging (Vascomax) retains its strength and has minimum distortion and deterioration, even after heat and pressure. It is a key material in the manufacture of all types of firing pins and breech blocks.

Maraging in Manufacturing
Maraging's ability to expand without cracking make it the material of choice for drill chucks. Its uniform machinability and durability make it ideal for producing gears in sophisticated robotic arms in assembly lines, and its high strength and wear resistance make it perfect for grippers in automation lines. Other Maraging (Vascomax) benefits for the manufacturing arena include excellent polishability and weldability with pre- or post heating.

Maraging in Tool & Die Making
Maraging has a significant cost advantage over other alloys. Uniform predictable shrinkage during heat treatment means Maraging does not require excessive reworking. It is easily machined. Its hardness and strength allow it to withstand the repeated pressures of compression molding for longer tool life with a very good surface finish.

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.
