A high-carbon, cobalt-strengthened martensitic stainless steel with elevated molybdenum and vanadium content, designed for extreme strength and wear resistance in demanding applications. This variant combines the corrosion resistance of 13% chromium stainless steels with significant hardening through carbon, cobalt, and molybdenum additions—a composition typical of premium tool steels and high-performance martensitic grades. Engineers select this material when exceptional hardness, compressive strength, and corrosion resistance must coexist, particularly in applications exposed to corrosive environments where conventional tool steels would fail.
