Maraging Steel Bars and Rods are high-alloy steels primarily made up of iron, containing 15–25% nickel, along with small amounts of cobalt, molybdenum, and titanium. Unlike traditional steels, maraging steel achieves its impressive strength through a process called aging (precipitation hardening) instead of relying on carbon content. This alloy boasts tensile strength ranging from 1,400 to 2,100 MPa and yield strength of 1,200 to 2,000 MPa after aging, all while maintaining excellent toughness and minimal distortion during heat treatment. Plus, maraging steel is known for its good weldability and machinability when in its annealed state.

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.
These Maraging Steel Bars and Rods find extensive use in aerospace, defense, tooling, and high-performance engineering sectors. They’re perfect for crafting aircraft landing gear, rocket motor cases, shafts, gears, molds, and precision tools that require extreme strength and toughness. Additionally, they play a crucial role in motorsport components, high-stress structural parts, and scientific equipment that need to maintain dimensional stability under heavy loads. With their remarkable combination of high strength, toughness, and reliability, Maraging Steel Bars and Rods are the go-to choice for critical and high-performance applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
