Maraging 300 alloy steels material (also referred to as Maraging C300® and 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.

Maraging 300 Alloy Steels Features

Magellan Metals' Vascomax® 300 is a nickel/cobalt steel alloy that is essentially carbon-free, other alloying elements include moly, aluminum and titanium. This combination creates a superior maraging steel that maintains numerous beneficial features, including:
  • Extremely tough
  • Relatively soft
  • Maintains high strength & toughness
  • Ultrahigh tensile strength
  • Resists corrosion & crack propagation
  • Excellent cleanliness & polishability
  • Readily weldable
 

Maraging 300 Alloy Steels Material Properties

Due to its low carbon content, Maraging steel 300 provides good machinability and the ability to be cold-rolled up to 90% without cracking. This material also provides excellent weldability when aged following treatment to the heat-affected zone. Additionally, Maraging 300 Alloy Steels meet the following specifications:
  • AMS 6514
  • ASTM A 538
  • MIL-S-46850D
  • UNS K 93120

Maraging 300 Alloy Steels Material Applications

Maraging steel's strength and malleability in the pre-aged stage allows it to be more easily than other steels, reducing weight for a given strength. Maraging 300 also maintains very stable properties and will only soften slightly when overaged due to excessive temperature reception. This 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 C300 is generally used for, include:
  • Missile & rocket motor cases
  • Munitions
  • Landing gear components
  • Aerospace
  • Extrusion tooling
  • Die casting
  • High performance shafting, gears & fasteners

Vascomax® 300 (Maraging C300) Available Formats

Maraging 300 is one of a family of "maraging" nickel steels such as Maraging 250® & Maraging 350® which are martensitic yet ductile in the solution treated condition and attain ultra-high-strength through a single low-temperature aging treatment. Magellan Metals offers nickel/cobalt alloy maraging C300 in a variety of forms, including:
