Vascomax® Maraging Steel

Maraging steel alloy products are manufactured through a martensitic steel heat treatment process that creates a unique class of low-carbon maraging steel. When compared with standard steel alloys, maraging steel delivers superior strength, toughness, workability, and heat treatment capabilities. All Magellan Metals maraging steel products meet AMS 612, ASTM A 538, MIL-S-46850D and NS K92890 specifications.

At Magellan Metals, we are your direct maraging metal manufacturers and suppliers. We provide custom work, short lead times, and quick delivery for all types of large or small quantities and shapes including tube, pipe, wire, sheet, and plate. We are also ISO Certified and provide advanced design expertise for all your maraging steel alloy needs.

For more information regarding our maraging steel alloy options including Vascomax® 250, 300, and C350get in touch with our sales staff or request a quote today. Magellan Metals is your trusted source for premium maraging steel materials.

Maraging Steel Alloy Options

Magellan Metals offers several grades of maraging steel alloys that are available in a wide range of formats including wire, plate, sheet, pipe fittings, bar, flanges, and more. View the individual product pages below for more information about the chemical analysis, available formats, and applications for each grade of maraging steel alloy.
  • Vascomax® 250Exhibits good ductility at high strength levels and is readily welded, providing excellent cleanliness and polishability.
  • Vascomax® 300 This vacuum induction melted and vacuum arc re-melted, low-carbon, nickel-cobalt-molybdenum high-temperature nickel alloy actively resists corrosion and crack propagation.
  • Vascomax® C350 – A relatively soft nickel-maraging alloy, Vascomax® C350 is readily machined and formed while allowing close machining with minimal distortion.

Maraging Steel Alloy Advantages

Maraging steel is an ultra-high strength, low-carbon steel that provides a high value for critical parts in aerospace, structural, component and tooling applications. Maraging steel provides the following beneficial qualities:
  • High fatigue strength
  • Increased workability
  • Excellent yield & tensile strength
  • Good toughness & ductility
  • Enhanced weldability
  • Heat treatment features
  • High fatigue strength

Maraging Steel Applications

Maraging material also has an excellent strength-to-weight ratio so it can be used for numerous defense and military purposes. Some of the applications that maraging alloys are generally used for, include:
  • Dies
  • Pistons
  • Shafts
  • Aerospace and aircraft parts
  • Mandrels
  • Rocket motor cases
  • Auto racing parts
  • Recoil springs
  • 3D printed parts

Maraging Steel Alloy Chemical Properties

The chemical composition of maraging steel is generally high in nickel, cobalt, and molybdenum. The carbon content in maraging steel’s chemical composition is considered an impurity and is generally kept to values of less than 0.03 per cent. The following table describes the chemical compositions of the different alloy grades of maraging steel.
Grade Ni % Mo % Co % Ti % Al %
Vascomax® 250              18.5 4.8 7.5 0.40 0.10
Vascomax® 300       18.5 4.8 9.0 0.60 0.10
Vascomax® 350       18.5 4.8 12.0 1.40 0.10
Additionally, the AMS and MIL specifications for Magellan Metals maraging steel alloys are:
Maraging C250 — AMS 6512; MIL-S-46850D
Maraging C300 — AMS 6514; MIL-S-46850D
Maraging C350 — AMS 6515; MIL-S-46850D

Maraging Steel Machinability

Due to its excellent mechanical properties and good workability, maraging steel alloys provide enhanced machinability over other types of steel alloys. The low efficient of expansion minimizes heat checking, providing longer tool life and superior pitting and corrosion resistance.
