Fe10CoN8

Fe10CoN8 is an iron-cobalt-nitrogen interstitial alloy, likely part of the high-nitrogen steel or interstitial alloy research family. This material combines iron and cobalt as primary elements with nitrogen as an interstitial strengthening agent, creating a system designed for enhanced hardness and strength at relatively low density. The nitrogen content suggests this is primarily a research or specialty alloy; such materials are investigated for applications requiring high strength-to-weight ratios and wear resistance, with potential use in demanding structural or tribological applications where conventional stainless steels or tool steels may be inadequate.
