Maraging steel is an ultra-high strength, low-carbon iron-nickel alloy, typically containing around 17-19% nickel, along with cobalt (about 7-12%), molybdenum (around 3-5%), titanium (approximately 0.2-1.6%), and trace amounts of aluminum. Its mechanical properties, when aged, showcase impressive tensile strength that can exceed 1,700-2,400 MPa depending on the grade, along with a yield strength that, while slightly lower, remains exceptionally high. It also boasts good toughness—even in sub-zero temperatures—moderate elongation (usually around 6-15%), and outstanding fatigue and impact resistance.

The maraging steel bars produced by Marsh Nickel Alloys find their way into applications that demand extraordinary strength with minimal deformation. Common uses include components for aerospace and defense (like landing gear and missile casings), high-performance tooling (such as dies and extrusion tools), and precision parts in motorsports and robotics, as well as high-stress shafts and gears. Their excellent machinability (before aging), dimensional stability, and high performance under load make these bars perfect for applications where failure simply isn’t an option.
