17Ni-8Co-2.9Mo-0.8Ti Maraging Steel

metal

17Ni-8Co-2.9Mo-0.8Ti is a precipitation-hardening maraging steel engineered for ultra-high strength with retained toughness and ductility. The nickel-cobalt-molybdenum-titanium composition enables age-hardening to develop exceptional strength levels while maintaining fracture resistance, making it suitable for critical structural applications where weight savings and reliability are paramount.

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.
