Maraging is a 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, structur-al, component and tooling applications.

NOTE: Amodified 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叶F for 1 hour per inch of thickness is typical. After finish machining, an aging heat treatment of
980-1000 °F for 6 hours is typical.

FAQ
Q: Is the VIM+VAR melting process essential for AMS 6514 C300?
A: Yes, it is critical. At 300 ksi strength levels, standard air-melted steel is too brittle. VIM (Vacuum Induction Melting) plus VAR (Vacuum Arc Remelting) removes oxygen and nitrogen impurities, ensuring the high fracture toughness required for aerospace parts.
Q: Does Maraging C300 need to be quenched after machining?
A: No. Unlike carbon steels, maraging steel does not require a quenching step. It is hardened solely by aging at a relatively low temperature (900–925°F / 482–496°C) for 6 hours, resulting in minimal distortion.
Q: How much shrinkage occurs during the aging process?
A: The shrinkage is highly predictable at approximately 0.001 inch per inch (0.1%). You should machine your part slightly oversized, leaving a grinding allowance, and finish machine it after the aging heat treatment to hold tight tolerances.
Q: What is the difference between C250 and C300 maraging steel?
A: C300 offers higher tensile strength (~300 ksi) and yield strength than C250. However, C250 has slightly better fracture toughness and ductility. If your application requires maximum strength and weight savings, C300 is the better choice.
Q: Can you supply Maraging C300 in small bars for prototype machining?
A: Yes. Our minimum order quantity is 1 metric ton for production, but we can cut short trial lengths from stock. The base material is supplied in the annealed and descaled condition, making it ready for your machining.
