0.05C 5.0Cr-1.6Mo-11.6Ni Low Alloy Steel
metalThis is a precipitation-hardening nickel-chromium-molybdenum steel with very low carbon content (0.05% C), formulated to achieve high strength while maintaining toughness and corrosion resistance through a combination of substitutional alloying and fine-scale hardening phases. The composition—particularly the elevated nickel (11.6%), chromium (5%), and molybdenum (1.6%) alongside trace additions of titanium, aluminum, and vanadium—is characteristic of maraging or secondary-hardening low-alloy steels designed for aerospace and precision engineering applications where weight efficiency and damage tolerance are critical. This material is chosen over conventional quenched-and-tempered steels or austenitic stainless steels when engineers need the damage-tolerance properties of a ferritic matrix with strength levels comparable to much harder alloys, and the fine grain structure supports excellent fatigue and impact performance in service.
