Description of HAYNES 188 Plate/Sheet

Alloy 188 is a cobalt-base superalloy with a unique combination of high and oxidation resistance, along with adequate ductility after prolonged exposure to the 1400-1600 °F temperature range. Cobalt alloys have an inherent advantage over the nickel base grades in high-temperature creep. Alloy 188 is a solid solution strengthened by a 14% tungsten addition, and further by M6CC and M23C6 carbides.
