16Cr Martensitic Stainless (var. 13)
metalA high-carbon, cobalt-strengthened martensitic stainless steel with elevated chromium and molybdenum content, designed to achieve exceptional hardness and wear resistance through precipitation hardening. This material combines corrosion resistance typical of stainless steels with the strength and hardness characteristics of tool steels, making it suitable for demanding applications where both durability and corrosion protection are critical. The high carbon content and vanadium addition promote fine carbide formation, while cobalt enhances strength at elevated temperatures—a combination that distinguishes it from conventional 13% Cr martensitic grades used in pumps and valves.
