0.05C 17.4Ni-0.6Mo Low Alloy Steel

metal

This 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.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
