Maraging 300 alloy steels material (also referred to as Vascomax C300) is a vacuum induction melted and vacuum arc re-melted, low-carbon, nickel-cobalt-molybdenum high-temperature nickel alloy. This material can produce yield strengths in excess of 270 ksi (1862 MPa) through simple, low-temperature heat treatment at 900°F (482°C). Maraging steel 300 also exhibits good ductility at high strength levels, displays excellent notch ductility and outstanding weldability.

Material Melt Method : Maraging melt method is a VIM (Vacuum Induction Melt) + VAR (Vacuum Arc Remelt)
As Shipped Condition : Maraging is supplied in the annealed and descaled condition. The alloy is very tough, relatively soft (36 Rc Max.), therefore, readily machined and formed.
The following table shows the physical properties of maraging 300 alloy steel.
|Density||8.00 g/cm3||0.289 lb/in³|
|Melting point||1412.8 °C||2575°F|
Minimum Properties after Aging:
- Hardness …… 52 Rc
- Charpy V-notch … 12 ft/lbs. min
- Reduction of Area ……. 47%
- Elongation ……. 5.0%
- Yield Strength …. 280 ksi
- Fracture Toughness ….. 60
Heat Treatment Aging Process: (Non Die Casting Applications) 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 .001 in/in
Heat Treatment Aging Process: (Die Casting Applications) 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.
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.
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.
