18Ni-8Co-3.6Mo-0.5Ti Maraging Steel
metal18Ni-8Co-3.6Mo-0.5Ti is a precipitation-hardening maraging steel engineered for ultra-high strength with excellent toughness and dimensional stability. This alloy is widely deployed in aerospace structures (landing gear, fasteners, critical forgings), tool steels for high-performance dies, and defense applications where weight savings and damage tolerance are critical. Engineers select maraging steels over conventional high-strength alloys when damage-tolerant fracture mechanics, low distortion during heat treatment, and repeatable performance in critical load-bearing roles are essential—making it the reference material for applications where strength-to-weight ratios and reliability cannot be compromised.

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.
