SAM provides high-quality HAYNES 188 (Alloy 188, UNS R30188) Plate/Sheet in a variety of sizes and dimensions to enable the most efficient production at your location. We offer quick turnaround and customized solutions for our customers per your needs.
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.
