Chromium nitride (CrN) is a transition metal nitride ceramic coating and bulk material known for exceptional hardness and wear resistance. It is widely used in industrial tooling, cutting applications, and protective coatings on mechanical components where high-temperature stability and corrosion resistance are critical. Engineers select CrN over uncoated steel or softer alternatives when extended tool life and reduced friction losses justify the coating cost, particularly in demanding machining, stamping, and sliding-contact applications.
