Maraging Steel Rods are typically available in sizes ranging from 0.125 inches (3.175 mm) to 12 inches (305 mm) in diameter, with lengths varying from 12 inches (300 mm) to 20 feet (6 meters).
Yes, Maraging steel bars can be welded, but they require careful control of heat input and pre/post-weld heat treatment to avoid compromising the material’s strength and toughness.
Maraging steel rods are typically available in diameters ranging from 0.25 inches to 8 inches. Common finishes include cold drawn, polished, or ground, with standard lengths between 12 and 24 feet.
Maraging Steel Bars and Rods are widely utilized in industries that demand high strength, reliability, and precision. They are perfect for aerospace components like landing gears, rocket motor casings, and structural parts of aircraft. In the defense sector, they are employed in missile casings and high-performance weapon systems. The tooling industry relies on maraging steel for dies, molds, and shafts due to its remarkable toughness and wear resistance. Additionally, it is used in motorsport engineering, power transmission shafts, and high-stress mechanical assemblies where superior strength-to-weight ratios are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
