Hayness 188 (Alloy 188) waa daawaha cobalt-saldhig leh awood heerkul aad u heer sare ah iyo iska caabin oksaydh oo wanaagsan 2000°F (1093°C).Heerka sare ee chromium oo ay weheliso wax yar oo lagu daro lanthanum waxay soo saartaa miisaan difaac oo aad u adag.Daawaha waxa kale oo uu leeyahay iska caabin sulfidation oo wanaagsan iyo xasillooni birta ah oo aad u fiican sida ay muujinayso ductility wanaagsan ka dib soo-gaadhista muddada dheer ee heerkulka sare.Wax-soo-saarka wanaagsan iyo alxanka ayaa isku darsa si ay uga dhigaan daawaha faa'iido u leh codsiyada gaaska marawaxadaha sida combustors, kuwa ololka haya, mashiinnada iyo marinnada kala-guurka.
