19Ni-15Co-1.8Mo-1.9Ti Maraging Steel

metal

19Ni-15Co-1.8Mo-1.9Ti is a precipitation-hardening maraging steel engineered for extreme strength with minimal ductility loss, achieving hardness through intermetallic phase formation rather than carbon content. Its nickel-cobalt-molybdenum-titanium system is deployed in aerospace structural components, defense systems, and precision tooling where weight savings and damage tolerance are critical; engineers select maraging steels over conventional high-strength steels when fatigue resistance, toughness, and dimensional stability during heat treatment are equally important to raw strength.

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.
