13Ni-13Co-0.7Ti Maraging Steel

metal

This is a nickel-cobalt maraging steel, a precipitation-hardening iron-based superalloy engineered for ultra-high strength with maintained toughness at modest temperatures. The alloy combines a martensitic iron matrix (~62% Fe) with significant nickel (13%) and cobalt (13%) hardeners, plus chromium for corrosion resistance and titanium for age-hardening via intermetallic precipitation, making it belong to the 18Ni maraging family adapted for enhanced cobalt content. This material is used in aerospace and military applications requiring exceptional strength-to-weight ratios and damage tolerance—such as landing gear components, structural fasteners, and high-performance tooling—where it outperforms conventional tool steels and stainless steels by delivering superior strength without brittleness, though at higher cost and requiring controlled heat treatment protocols.

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.
