Neil Metals, based in Kolkata, India, has made a name for itself as a top-notch manufacturer and supplier of Maraging Steel Bars and Rods. They specialize in high-strength, low-carbon alloys that are perfect for industries needing outstanding toughness, ductility, and dimensional stability. With a strong commitment to quality, innovation, and precision, Neil Metals provides maraging steel products that not only meet global standards but also serve critical sectors like aerospace, defense, tooling, and motorsports. Thanks to their advanced manufacturing setup and a talented technical team, the company guarantees consistent performance, timely delivery, and long-lasting reliability of their maraging steel bars and rods, which are essential for demanding structural and engineering applications.
Maraging Steel Bars and Rods are primarily made of iron and nickel, usually between 18% and 25%, along with other elements like cobalt, molybdenum, titanium, and aluminum. These alloys achieve ultra-high strength through age hardening rather than relying on carbon, reaching tensile strengths over 2000 MPa. They boast excellent fracture toughness, superior machinability when annealed, and remarkable dimensional stability during heat treatment. The low carbon content not only improves weldability but also reduces the risk of cracking, making these alloys perfect for precision-engineered components that face high stress and thermal exposure.

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.
You’ll find Maraging Steel Bars and Rods in a variety of applications, from aerospace structures and aircraft landing gear to rocket motor casings and high-performance automotive parts, all thanks to their impressive strength-to-weight ratio. In the tooling industry, they’re used to create extrusion dies, die-casting tools, and injection molds where high wear resistance and toughness are crucial. They also play a role in nuclear reactors, military-grade hardware, and professional sporting equipment. The ability of maraging steel to maintain its mechanical integrity under extreme loads and temperature changes makes it vital for applications that demand high reliability and performance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
