15Cr Martensitic Stainless (var. 7)

This is a martensitic stainless steel with 15% chromium, elevated carbon content (~1.16%), and molybdenum alloying, formulated for high hardness and wear resistance. Typical applications include tool steels, precision cutting instruments, and wear-resistant pump components where corrosion resistance must be balanced against the need for exceptional hardness and edge retention. The cobalt addition (~13%) is notable and suggests potential aerospace or high-temperature applications, setting this variant apart from standard 15Cr martensitic grades by enhancing toughness and thermal fatigue resistance in demanding environments.
