Brand: MatWorld

metal

This is a precipitation-hardened maraging steel (18% Ni-class equivalent) strengthened by cobalt, molybdenum, and titanium additions, designed to achieve high strength with useful toughness and damage tolerance. It is used primarily in aerospace and defense applications where components must withstand extreme loads while maintaining reliability—such as landing gear, rocket motor casings, and structural fasteners—and is chosen over conventional steels or titanium alloys when a combination of high yield strength, fatigue resistance, and repairability (via welding) is critical.

Quality & Standards

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.
