HS 21(Co-Cr-Mo)

1. Introduce – HS : Abbreviation for Haynes Stellite – Developed as a corrosion-resistant CoCr(Mo) alloy – Applied as a biocompatible hip implant and denture alloy – Most of the alloys currently used in medical applications are variations of HS 21 – Consists of a CoCrMo alloy base containing dispersed hard carbides that strengthen the alloy and increase hardness but decrease ductility – Oxidation and reduction resistance up to a temperature range of 1150°C – UNS R30021, W73041, W73021 * Stellite Alloys A Co-Cr alloy designed for wear resistance Alloys ...
