Ko te Hayness 188 (Alloy 188) he koranu-tupapa-koparati me te kaha o te teitei-temperature tino pai me te pai o te aukati waikura ki te 2000°F (1093°C).Ko te taumata chromium teitei me nga taapiri iti o te lanthanum ka puta he tauine tino kaha me te tiaki.Ko te koranu he pai hoki te aukati sulfidation me te tino pai o te whakarewatanga o te whakarewatanga e whakaatuhia ana e te pai o te ductility i muri i te roanga o te rongo ki nga pāmahana teitei.He pai te hanga me te weldability ka whakakotahi kia whai hua te koranu i roto i nga tono turbine hau, penei i te whakawera, te pupuri mura, te raina me nga riu whakawhiti.
