I-Incoloy alloy 925 (I-UNS N09925) kunye nokongezwa kwe-molybdenum, i-copper, i-titanium, kunye ne-aluminium yi-alloy ye-nickel-iron-chromium eqina ixesha elide, enika indibaniselwano yamandla aphezulu kunye nokumelana nokugqwala okugqwesileyo. Umxholo owaneleyo we-nickel ubonelela ngokhuseleko ekuqhekekeni kwe-chloride-ion stress-corrosion ngelixa xa idibene ne-molybdenum eyongeziweyo kunye ne-copper, ukumelana neekhemikhali ezinciphisayo kuyananditshwa. I-Molybdenum ikwanceda ekuchaseni ukugqwala kwe-pitting kunye ne-crevice, ngelixa i-chromium inika ukumelana neendawo ezikhupha i-oxidizing. Ngexesha lonyango lobushushu, impendulo eyomelezayo ibangelwa kukongezwa kwe-titanium kunye ne-aluminium.

Ukusetyenziswa okufuna indibaniselwano yamandla aphezulu kunye nokumelana nokugqwala kunokuqwalasela i-Incoloy alloy 925. Ukuxhathisa ukuqhekeka koxinzelelo lwe-sulfide kunye nokuqhekeka koxinzelelo-ukugqwala kwiindawo ze-oyile ekrwada "emuncu" kunye negesi yendalo kuthetha ukuba isetyenziselwa izinto ezingaphantsi komhlaba kunye negesi kunye nomphezulu kunye nokufumana ukusetyenziswa kwi-marine kunye ne-pump shafts okanye iinkqubo zepayipi ezinamandla aphezulu.
