0.05C 16.5Ni-1.2Mo Low Alloy Steel

metal

This is a high-nickel, low-carbon maraging steel strengthened by molybdenum and titanium additions, designed to achieve very high yield strength with retained toughness and low distortion during heat treatment. Maraging steels like this composition are primarily used in aerospace and defense applications where light weight, dimensional stability, and exceptional strength-to-weight ratio are critical—such as landing gear, rocket casings, and pressure vessels. The low carbon content and precipitation-hardening mechanism (rather than carbon diffusion) make this alloy particularly attractive for thick sections and complex geometries where conventional high-strength steels would suffer from brittleness, distortion, or difficult machining.

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.
