 Unlike some other high-performance alloys, Eglin steel can be welded easily, broadening the range of its application.Also, it uses roughly half as much nickel as other superalloys, substituting silicon to help with toughness and particles of vanadium carbide and tungsten carbide for additional hardness and high-temperature strength.The material also involves chromium, tungsten, and low to medium amounts of carbon, which contribute to the material's strength and hardness.
