I-Hayness 188 (Ingxubevange 188) iyingxubevange ye-cobalt-base enamandla asezingeni eliphezulu kakhulu lokushisa kanye nokumelana okuhle kwe-oxidation ku-2000°F (1093°C).Izinga eliphezulu le-chromium elihlanganiswe nezithako ezincane ze-lanthanum kukhiqiza isikali esiqinile nesivikelayo.Ingxubevange futhi inokumelana okuhle kwe-sulfidation kanye nokuzinza okuhle kakhulu kwe-metallurgical njengoba kuboniswa yi-ductility yayo enhle ngemva kokuchayeka isikhathi eside emazingeni okushisa aphakeme.Ukwenziwa okuhle nokushisela kuhlangana ukwenza ingxubevange isebenziseke ezinhlelweni ze-turbine yegesi njengezibasi, izibambi zomlilo, amalayini namapayipi oguquko.

•Amandla kanye ne-oxidation ukumelana no-2000°F
•I-ductility enhle ngemuva kokuguga
•Imelana ne-sulfate ifaka ukugqwala okushisayo
Amathini enjini ye-turbine yegesi, izinsimbi zokufutha, izinto zokubamba amalangabi kanye nolayini we-afterburner
