18Ni-13Co-2.1Mo-2.7Ti Maraging Steel
metalAn 18% nickel maraging steel strengthened by precipitation hardening of intermetallic phases (cobalt, molybdenum, and titanium), achieving ultrahigh strength with relatively good toughness compared to conventional high-strength steels. This material is used in aerospace structures, rocket casings, and precision tooling where extreme strength-to-weight ratio and dimensional stability are critical; it is valued over alternatives because it can be solution-treated in thick sections and then aged to full strength without significant distortion, making it ideal for large forged components that demand both strength and machinability.

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.
