815 MPA lncoloy 925 UNS N09925 Corrosion strip Alloy
Ingxubevange ye-Incoloy 925 (I-UNS N09925) enezengezo ze-molybdenum, ithusi, i-titanium, ne-aluminium ingxubevange ye-nickel-iron-chromium eqinile ngeminyaka, enikeza inhlanganisela yamandla aphezulu kanye nokumelana nokugqwala okuhle kakhulu. Okuqukethwe kwe-nickel okwanele kunikeza isivikelo ekuqhekekeni kwe-chloride-ion stress-corrosion ngenkathi kuhlangene ne-molybdenum eyengeziwe nethusi, ukumelana nokunciphisa amakhemikhali kuyajatshulelwa. I-Molybdenum isiza futhi ekumelana nokugqwala kwe-pitting kanye nokuqhekeka, kuyilapho i-chromium inikezela ukumelana nezindawo ezikhiqiza i-oxidizing. Ngesikhathi sokwelashwa kokushisa, ukusabela okuqinisayo kubangelwa ukwengezwa kwe-titanium ne-aluminium.
Izicelo ezidinga inhlanganisela yamandla aphezulu kanye nokumelana nokugqwala zingase zicabangele i-Incoloy alloy 925. Ukumelana nokuqhekeka kwe-sulfide stress kanye nokuqhekeka kwe-stress-corrosion endaweni “emuncu” kawoyela ongahluziwe negesi yemvelo kusho ukuthi isetshenziselwa imbobo ephansi kanye nezingxenye zemithombo yegesi engaphezulu kanye nokuthola ukusetshenziswa kwamapayipi amapayipi asolwandle noma amaphampu aphezulu.
