18Ni-8Co-2.9Mo-0.9Ti Maraging Steel
metal18Ni-8Co-2.9Mo-0.9Ti is a precipitation-hardening maraging steel engineered for extreme strength with retained toughness, developed through aging heat treatment rather than carbon hardening. This alloy is used in critical aerospace components, tooling for high-pressure molding, and precision machinery where weight savings and damage tolerance are essential—particularly applications requiring both exceptional strength and ability to absorb impact without brittle failure. The cobalt and molybdenum additions enable superior hardening response compared to conventional steels, making maraging steel the material of choice when conventional high-strength alloys prove inadequate or too brittle.

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.
