metal

17Ni-12Co-2.4Mo-1.9Ti is an ultra-high-strength maraging steel engineered for extreme performance applications where weight savings and damage tolerance are critical. The high nickel and cobalt content, combined with molybdenum and titanium strengthening elements, enables this alloy to achieve exceptional strength levels while maintaining fracture toughness and dimensional stability—characteristics that distinguish it from conventional structural steels and competing superalloys. This grade is favored in aerospace, defense, and precision tooling industries where the combination of high strength-to-weight ratio, low distortion during heat treatment, and excellent fatigue resistance justify its premium cost.

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.
