Maraging 300 / VASCOMAX® 300 Steel - AMS 6514
Maraging 300 / VASCOMAX® 300 is an 18% nickel, cobalt strengthened steel (C-type) with excellent properties, workability and heat treatment characteristics. Maraging is double vacuum melted by VIM (Vacuum Induction Melt) followed by VAR (Vacuum Arc Remelt). Maraging material is supplied in the annealed and descaled condition. The alloy is very tough, relatively soft (RC 30/35), readily machined or formed. Maraging provides a high value for critical parts in aerospace, structural, component and tooling applications.
Service Steel Aerospace has Maraging / VASCOMAX® 300 available in billet, bar, rod, plate, sheet, and customized forgings
Maraging ;>MARtensitic - a very hard form of steel crystalline structure.Subsequent AGING (precipitation hardening - approx 3-6 hours @ 900ºF yields optimum material characteristics)

| Modulus of Elasticity | 27.5 x 10-6 psi |
| Average Co of Thermal Expansion | 5.6 x 10-6 in/in/°F |
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.
| Temperature | Time | Resulting Hardness |
|---|---|---|
| 900/925 °F | 6 hrs | 50/55 Rc |
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.
