I-Incoloy 925 yi-alloy ye-precipitable yokuqina esekelwe kwi-alloy ye-Fe-Ni-Cr kunye nokongezwa kwe-molybdenum, ubhedu, i-titanium kunye ne-aluminium.I-alloy inamandla aphezulu kunye nokumelana nokugqwesa okugqwesileyo kwisicelo.Umxholo we-nickel wanele ukukhusela i-alloy kwi-corrosion kunye nokuqhekeka nge-ion chloride.Indibaniselwano ye-nickel, i-molybdenum kunye nobhedu ikwanika i-alloy ukuxhathisa okugqwesileyo ekunciphiseni imichiza.I-Molybdenum inceda ekuphuculeni ukuxhathisa kwi-pitting kunye ne-corrosion.Inxalenye yechromium yealloyi ibonelela ngokumelana ne-oxidation ngokuchasene nemeko yokunciphisa.Ukongezwa kwe-titanium kunye ne-aluminium kunokomeleza i-alloy ngexesha lonyango lokushisa

I-Carpenter Alloy 925 yamkelwe kwi-NACE MR0175.
NACE MR0175
Amandla omatshini alungileyo kunye nokuxhathisa okukhulu kokubola.
Inokumelana ne-corrosion efanelekileyo kwi-chloride ion stress corrosion, i-corrosion yendawo kunye neentlobo ezahlukeneyo zokunciphisa i-oxidizing media media.
I-Commonl esetyenziswa kwi-oyile kunye negesi ye-drillinga equoment parts kunye namacandelo.njengemibhobho, iivalvu, ioint bositioning, isixhobo ioint packer, ekwasetyenziswa ekwenzeni ezinye iziqhoboshi.
