I-alloy 686 sisigaba esinye, i-austenitic ye-Ni-Cr-Mo-W ingxubevange enika i-corrosion-resisance ebalaseleyo kuluhlu lweemeko ezimandundu.I-nickel yayo ephezulu (i-Ni) kunye ne-molybdenum (Mo) inikezela ukuchasana kakuhle kwiimeko zokunciphisa, kunye ne-chromium ephezulu (i-Cr) inikezela ukuchasana ne-oxidizing media.I-Molybdenum (Mo) kunye ne-tungsten (W) inceda ukuxhathisa kwi-corrosion yendawo efana ne-pitting.I-Iron (Fe) ilawulwa ngokusondeleyo ukuphucula iimpawu.Ikhabhoni ephantsi (C) inceda ukunciphisa imvula yomda wokuziinkozo ukuze kugcinwe uxhathiso lwe-corrosion kwiindawo ezichatshazelwe bubushushu bamalungu adityanisiweyo.

1.Ukuchasana okuhle ekunciphiseni iimeko;
2.Ukuchasana okuhle kwimidiya ye-oxidizing;
3.Ukuxhathisa ngokubanzi, ukubola kwemingxuma kunye nemingxuma kuyanda.
imidiya ndlongo ekusetyenzweni kweekhemikhali, ulawulo longcoliseko, ipulp kunye nokuveliswa kwephepha, kunye nezicelo zolawulo lwenkunkuma.
