Ingxubevange ye-Incoloy 925 (I-UNS N09925) kunye nezongezo ze-molybdenum, ubhedu, i-titanium, kunye ne-aluminium yi-alloy ye-nickel-iron-chromium enzima yobudala, inika indibaniselwano yamandla aphezulu kunye nokumelana nokugqwesa okugqwesileyo. Umxholo we-nickel owaneleyo unika ukhuseleko kwi-chloride-ion stress-corrosion cracking ngelixa idibene ne-molybdenum eyongezelelweyo kunye nobhedu, ukuchasana nokunciphisa imichiza kuyayoliswa. I-Molybdenum iphinda incede ekuxhathiseni ukugoba kunye ne-corrosion, ngelixa i-chromium inika ukuchasana neendawo ze-oxidizing. Ngethuba lokunyanga ukushisa, ukusabela okomeleza kubangelwa ukongezwa kwe-titanium kunye ne-aluminium.

Izicelo ezifuna indibaniselwano yamandla aphezulu kunye nokumelana nomhlwa zisenokuthathela ingqalelo i-Incoloy alloy 925. Ukumelana nokuqhekeka koxinzelelo lwesulfide kunye nokuqhekeka kwe-stress-corrosion kwindawo ekrwada ekrwada “emuncu” kunye nerhasi yendalo kuthetha ukuba isetyenziselwa umngxuma osezantsi kunye namalungu erhasi emphezulu ngokunjalo nokufumana ukusetyenziswa kwimibhobho yolwandle kunye neyokumpompa imibhobho ephezulu.
