1. Xa kuthelekiswa ne-904L, i-S32750 i-double-phase-steel ine-corrosion resistance to dilute sulfuric acid exutywe ne-chloride ion.
I-904L yi-alloy ye-austenitic eyenzelwe ngokukodwa ukuxhathisa ukubola kwe-asidi ye-sulfuric ecocekileyo.
I-chromium ephezulu kunye nomxholo we-molybdenum we-S32750 we-double-phase iron yenza ukuba ixhathise ngakumbi kwi-corrosion yonke ye-organic acids njenge-asidi kunye ne-acetic acid.
I-S32750 i-duplex steel nayo inokumelana ne-corrosion eyomeleleyo kwi-inorganic acids, ngakumbi ezo zinekloridi.
IBanga le-316L alinakusetyenziswa kwiindawo ezine-hydrochloric acid apho inokuthi ibe phantsi kwe-corrosion yendawo okanye yehlabathi.
I-S32750 yentsimbi yesigaba esiphindwe kabini ingasetyenziselwa kwindawo edibeneyo ye-hydrochloric acid, ngokuxhathisa olomeleleyo kumonakalo wamabala kunye nokukwazi ukubola.
2. I-Intercrystalline corrosion S32750 i-double-phase steel inomxholo wekhabhoni ophantsi, onciphisa kakhulu umngcipheko we-intercrystalline carbide precipitation ngexesha lonyango lokushisa.Ke ngoko, le alloy ixhathisa kakhulu kwi-carbon-related intercrystalline corrosion.
3. Uxinzelelo lwe-corrosion cracking: ngenxa yomxholo ophezulu we-alloy, ukuxhatshazwa kwe-corrosion kunye namandla e-S32750 yentsimbi ye-double-phase ingcono kune-2205.
I-S32750 kabini-isigaba sentsimbi esakhiweyo senza ukuba sixhathise ngakumbi ukunyanzeliswa kwekhono lokuqhekeka kwe-corrosion.
I-4, i-corrosion kunye ne-corrosion: kukho iindlela ezininzi zokuvavanya ukuxhathisa ukubola kweemveliso zetsimbi kwisisombululo esine-chloride.Ukushisa okubalulekileyo kwi-corrosion kunye ne-corrosion ye-high-performance steel stainless steel kwi-1M isisombululo se-sodium chloride sicacisiwe.
Iziphumo ezahlukeneyo zovavanyo zibonisa ukuba i-S32750 ezimbini-inqanaba lentsimbi inokumelana nokugqwala okugqwesileyo.
I-5, i-crack corrosion: i-crack corrosion: ii-cracks kwisakhiwo kunye nezinye iinkalo ziphantse zingenakuphepheka, okwenza insimbi engenasici isengozini ngakumbi kwi-corrosion kwindawo ye-chloride.
