0.09C 14.7Ni-0.8Mo Low Alloy Steel
metalThis is a high-nickel maraging-class low-alloy steel, characterized by very low carbon content (0.09%), high nickel (14.7%), and molybdenum additions with significant titanium (2.47%) for age-hardening strengthening. The composition targets the maraging steel family, which achieves high strength through precipitation hardening rather than carbon-based mechanisms, making it particularly suitable for applications requiring excellent combination of strength and toughness at controlled hardness levels. This alloy is used in aerospace and defense applications where weight efficiency and reliable performance under demanding conditions are critical—such as landing gear, fasteners, pressure vessels, and structural components—and offers advantages over conventional high-carbon steels by providing superior fracture toughness and lower distortion during heat treatment.
