Ikoloy alloy 925 (UNS N09925) pamwe nekuwedzera kwe molybdenum, mhangura, titanium, uye aruminiyamu izera rinoomesa nickel-iron-chromium alloy, inopa musanganiswa wesimba rakakwirira uye yakanakisa corrosion resistance. Yakakwana nickel yemukati inopa dziviriro kubva kune chloride-ion stress-corrosion kuparuka nepo pamwe chete neinowedzerwa molybdenum nemhangura, kuramba kudzikisa makemikari kunonakidzwa. Molybdenum zvakare inobatsira mukupokana negomba uye kukoromoka kwegomba, nepo chromium ichipa kuramba kune oxidizing nharaunda. Munguva yekurapa kwekupisa, kugadzirisa kwekusimbisa kunokonzerwa nekuwedzerwa kwetitanium uye aluminium.

Zvikumbiro zvinoda kusanganiswa kwesimba rakakwirira uye kusagadzikana kwekuora kunogona kufunga nezveIncoloy alloy 925. Kurwisana ne sulfide stress cracking uye stress-corrosion cracking mu "sour" crude oil uye natural gas environments zvinoreva kuti inoshandiswa kune pasi-gomba uye pamusoro pegasi-well components pamwe nekutsvaga kushandiswa mumarine uye pombi mapiping shafts
