10Ni-12Co Maraging Steel

metal

10Ni-12Co maraging steel is an iron-based alloy strengthened primarily through precipitation hardening of intermetallic phases rather than carbon content, making it a low-carbon, high-nickel steel with cobalt and molybdenum additions. It is widely used in aerospace, defense, and high-performance tooling applications where exceptional strength-to-weight ratios and dimensional stability are critical—particularly in rocket motor cases, landing gear, pressure vessels, and precision dies. Engineers select maraging steels over conventional high-carbon steels when ultra-high strength combined with toughness and the ability to achieve fine dimensional tolerances without distortion is required, and increasingly for additive manufacturing applications where its weldability and post-processing characteristics offer advantages over martensitic alternatives.

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.
