I-alloy 686 iyingxube yesigaba esisodwa, i-austenitic ye-Ni-Cr-Mo-W enikeza ukumelana nokugqwala okuvelele endaweni ehlukahlukene enzima.I-nickel yayo ephezulu (Ni) ne-molybdenum (Mo) inikeza ukumelana okuhle ekunciphiseni izimo, futhi i-chromium ephezulu (Cr) inikeza ukumelana nemidiya ye-oxidizing.I-Molybdenum (Mo) kanye ne-tungsten (W) isiza ukumelana nokugqwala kwendawo okufana ne-pitting.I-ayoni (Fe) ilawulwa eduze ukuze kuthuthukiswe izakhiwo.Ikhabhoni ephansi (C) isiza ukunciphisa imvula yomngcele wokusanhlamvu ukuze kugcinwe ukumelana nokugqwala ezindaweni ezithinteke ukushisa zamajoyinti ashiselwe.

1.Ukumelana okuhle ekunciphiseni izimo;
2.Ukumelana okuhle nemidiya ye-oxidizing;
3.Ukumelana nokugqwala okujwayelekile, imigodi kanye nokugqwala kwemigodi kuyakhula.
imidiya eqinile ekucutshungulweni kwamakhemikhali, ukulawula ukungcoliswa komhlaba, ukukhiqizwa kwe-pulp nephepha, kanye nezicelo zokulawulwa kwemfucuza.
