Maraging steel is high-strength, low-alloy steel with superior strength and toughness due to its unique composition. It typically contains between 18%–25% cobalt, 12%–18% nickel, 5.5%-9% molybdenum, 0.2%-0.6 % carbon, and the remainder of iron and sometimes other elements such as chromium or manganese depending on its specific alloy composition. The addition of cobalt greatly increases the yield strength and tensile strength at room temperature while minimizing brittleness compared to traditional steels; it also displays excellent weldability, which makes it ideal for aerospace applications where weight savings are critical.
Maraging steel is an alloy of iron, carbon, and other elements, such as cobalt, molybdenum and titanium. It has excellent physical properties, such as high tensile strength and low weight, making it ideal for industrial applications requiring strength and durability yet minimal weight. Marging steel is often used in tools to create parts where heat-treatment hardening techniques are not available or feasible. This metal alloy is also used in aerospace components due to its combination of superior mechanical properties, including corrosion resistance and toughness at cryogenic temperatures.
