300-Maraging-Steel Round Bar Stock

300 maraging steel is ideal for high-strength structural applications.

300-Maraging-Steel

Maraging 300 steel material is made of a low carbon nickel, cobalt, and molybdenum high-temperature nickel alloy that has been induction-melted and then vacuum arc re-melted

The excellent strength-to-weight ratio of 300 maraging steel makes it ideal for high-strength structural applications, such as aircraft landing gear components and a variety of other defense and military applications.

 

In addition to molybdenum, aluminum, and titanium, 300 maraging steel uses nickel or cobalt steel, making it practically carbon-free. This combination results in superior maraging steel that retains various beneficial properties such as high strength and toughness, ultrahigh tensile strength, and extremely toughness while also being extremely strong.
