15Cr-8Ni-1.5Mo Stainless
metal15Cr-8Ni-1.5Mo is a martensitic stainless steel with significant cobalt and titanium additions, designed for high-strength applications requiring corrosion resistance. The cobalt strengthening and moderate molybdenum content position this alloy for aerospace, turbomachinery, and critical fastener applications where both corrosion resistance and elevated-temperature mechanical performance are demanded. Engineers select this composition over standard 300-series austenitic stainless steels when weight savings and higher strength-to-density ratios are critical, though its martensitic structure requires careful heat treatment and stress-relief protocols to avoid brittleness.
