Rupal Metals’ Maraging Steel Bars and Rods usually contain iron alloyed with 18–25% nickel and minor cobalt, molybdenum, and titanium. These ingredients bring outstanding mechanical properties, particularly following aging heat treatments. The product has very high yield strength—frequently even up to 2,000 MPa—combined with low carbon content, outstanding toughness, and excellent resistance to fatigue and crack growth. Maraging steel is also highly dimensionally stable, well-machinable, and weldable. All these attributes render it best suited for use in cases demanding accuracy and dependability in high-stress and high-performance environments.

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 from Rupal Metals find a widespread application in aerospace parts like aircraft frames, landing gears, and rocket motor casings, where strength and toughness are of utmost importance. In defense, they are used in missile casings, specialized equipment, and structural parts. These steel rods also find perfect application in high-strength tooling, die cast molds, and motor sports engineering. Their great mechanical stability and machinability render them ideal for precision instruments and industrial uses, such as nuclear reactors and robots. Rupal Metals guarantees consistent quality, which makes their maraging steel an ideal selection for rigorous engineering solutions.
