George Metals, a prominent manufacturer and supplier located in Houston, USA, specializes in high-quality Maraging Steel Bars and Rods designed for applications that demand exceptional strength, toughness, and dimensional stability. These bars are crafted using cutting-edge metallurgy techniques to ensure outstanding hardenability, machinability, and resistance to thermal distortion. Available in various grades like 18Ni (250, 300, 350), George Metals’ maraging steels find extensive use in critical components across industries such as aerospace, defense, tooling, and high-performance engineering. Renowned for their excellent aging response and weldability, these bars and rods promise a long service life and reliable performance in challenging load-bearing situations.
Maraging Steel is a low-carbon, ultra-high-strength alloy primarily made up of iron, 18–20% nickel, and trace amounts of cobalt, molybdenum, and titanium, with very little carbon content. These steels boast impressive tensile strengths ranging from 1400 MPa to over 2100 MPa, along with remarkable toughness, fatigue resistance, and minimal dimensional distortion post-heat treatment. Maraging steels are celebrated for their excellent machinability in the annealed state and can be precipitation hardened to achieve maximum strength. Their low thermal expansion and stable microstructure make them perfect for precision components that endure high stress and cyclic loading.
