I-HastelloyC alloy iyingxubevange ye-Ni-Cr-Molybdenum-Tungsten enikezela ukumelana nokugqwala okungcono kunamanye akhona e-Ni-Cr-Molybdenum-Hastelloy C276,C4 kanye nama-625 alloys.
Ama-alloys e-Hastelloy C anokumelana okuhle kakhulu ne-pitting, ukugqwala kwe-crevice kanye nokuqhekeka kokugqwala kwengcindezi.
Inokumelana okuhle kakhulu nemithombo yamanzi e-oxidizing, okuhlanganisa i-chlorine emanzi, i-nitric acid noma ingxube ye-oxidizing acid equkethe i-chloride ion.
Ngesikhathi esifanayo, ama-alloys e-Hastelloy C nawo anekhono elihle lokumelana nezindawo zokunciphisa kanye ne-oxidizing ezihlangabezane nazo phakathi nenqubo.
Ngalokhu kuguquguquka, ingasetshenziswa kwezinye izindawo ezinezinkinga, noma ezimbonini ngezinjongo ezihlukahlukene zokukhiqiza.
I-Hastelloy C alloy inokumelana okuyingqayizivele ezindaweni ezihlukahlukene zamakhemikhali, okuhlanganisa izinto ezinamandla ze-oxidizing, njenge-ferric chloride, i-chloride yethusi, i-chlorine, isisombululo sokungcola okushisayo (i-organic noma inorganic), i-formic acid, i-acetic acid, i-acetic anhydride, amanzi olwandle nesisombululo sikasawoti.
I-Hastelloy C alloy inamandla okumelana nokwakheka kwemvula yomngcele wokusanhlamvu endaweni ethintekile ekushiseni, okuyenza ifaneleke ezinhlotsheni eziningi zezinqubo zamakhemikhali esimweni sokushisela.

1.Ukumelana nokugqwala kusixazululo se-sulfuric acid yanoma yikuphi ukugxila kuze kube ngu-70 ℃, izinga lokugqwala cishe ngu-0.1mm/a.
2.Izinga lokugqwala lazo zonke izinhlobo ze-concentration hydrochloric acids alikho ngaphezu kuka-0.1mm/a ekamelweni lokushisa, lingaphansi kuka-0.5mm/a kuze kube ngu-65℃.Ukugcwaliswa komoyampilo ku-hydrochloric acid kuthonya kakhulu ukumelana nokugqwala.
3.Izinga lokugqwala lingaphansi kuka-0.25mm/a ku-hydrofluoric acid, lingaphezulu kuka-0.75mm/a ezimeni ezingu-55% H3PO4+0.8% HF ekushiseni okubilayo.
4.Ukumelana nokugqwala ukuze kuhlanjululwe i-nitric acid yakho konke okugxilile ekamelweni lokushisa noma izinga lokushisa eliphakeme, izinga layo licishe libe ngu-0.1mm/a, ukumelana nokugqwala okuhle kukho konke ukugxila kwe-chromic acid ne-organic acid kanye nenye ingxube kuze kube ngu-60 kuya ku-70 ℃, futhi izinga lokugqwala lingaphansi kuka-0.125mm/a no-0.175mm/a.
5.Enye yezinto ezimbalwa ezikwazi ukumelana nokugqwala kwe-chlorine eyomile nemanzi, ingasetshenziswa ezimeni zokugqwala ezishintshaniswa ngegesi ye-chlorine eyomile nemanzi.
6.Ukumelana nokugqwala kwegesi ye-HF yokushisa okuphezulu, izinga lokugqwala kwegesi ye-HF ngu-0.04mm/a kuze kufike ku-550℃,0.16mm/a kuze kufike ku-750℃.
