0.05C 9.7Cr-1.9Mo-8.1Ni Low Alloy Steel
metalA martensitic stainless steel with ~10% chromium and significant nickel and molybdenum additions, designed for high-strength applications requiring corrosion resistance and toughness. This composition is typical of precipitation-hardening or secondary-hardening stainless steels used in demanding aerospace, defense, and industrial tooling applications where both wear resistance and environmental durability are critical. The low carbon content combined with aluminum and titanium suggests age-hardening capability, making this alloy suitable for components that must withstand high stress while resisting corrosion in harsh environments.
