Haynes 188 Udimet alloy 188 UNS R30188

Short Introduction:

HY 188/Udimet alloy 188/Werkstoff 2.4683/Alloy 188/Inconel alloy 188/Haynes Alloy 188/UNS R30188 is a cobalt base super alloy 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.
