HY 188 is a cobalt base superalloy with a unique combination of high temperature strength and oxidation resistance, along with adequate ductility after prolonged exposure to the 1400-1600°F temperature range.Cobalt alloys have an herent advantage over the nickel base grades in high temperature creep.Alloy 188 is solid solution strengthened by a 14% tungsten addition, and further by M6C and M23C6 carbides
