0.05C 17.4Ni-0.6Mo Low Alloy Steel
metalThis is a low-alloy martensitic steel with exceptional nickel content (17.4%) and molybdenum (0.6%) additions, plus significant titanium and aluminum for strengthening and age-hardening effects. The extremely low carbon content (0.05%) combined with this alloying strategy produces a material designed for high-strength applications requiring good toughness and corrosion resistance—typical of aerospace-grade or ultra-high-strength structural steels. This composition family appears optimized for applications demanding both strength and damage tolerance where conventional high-carbon steels would be too brittle, making it competitive with premium alloy steels in demanding industries where failure is not an option.
