I-alloy ye-HastelloyC yi-alloy ye-Ni-Cr-Molybdenum-Tungsten ene-alloy enikezela ngcono ukuxhathisa ukubola kunezinye ezikhoyo ze-Ni-Cr-Molybdenum-Hastelloy C276, i-C4 kunye ne-625 alloys.
I-Hastelloy C alloys inokumelana okugqwesileyo kwi-pitting, i-crevice corrosion kunye noxinzelelo lwe-corrosion cracking.
Inokumelana okugqwesileyo kwimithombo yamanzi e-oxidizing, kuquka i-chlorine emanzi, i-nitric acid okanye umxube we-oxidizing acids equkethe i-ion chloride.
Ngelo xesha, i-alloys ye-Hastelloy C nayo inamandla afanelekileyo okumelana nokunciphisa kunye neendawo ze-oxidizing ezidibana nazo ngexesha lenkqubo.
Ngobu buguquguqukayo, bunokusetyenziswa kwiindawo ezinenkathazo, okanye kwiifektri ngeenjongo ezahlukeneyo zemveliso.
I-Hastelloy C ingxubevange inokuchasana okukhethekileyo kwiindawo ezahlukeneyo zeekhemikhali, kubandakanywa izinto ezinamandla ze-oxidizing, ezifana ne-ferric chloride, i-chloride yobhedu, i-chlorine, isisombululo sokungcola kwe-thermal (i-organic okanye i-inorganic), i-fomic acid, i-acetic acid, i-acetic anhydride, amanzi olwandle kunye nesisombululo setyuwa.
I-Hastelloy C ingxubevange inamandla okuxhathisa ukubunjwa komda wengqolowa kwindawo echaphazelekayo yokushisa kwi-welding, eyenza ukuba ifaneleke kwiintlobo ezininzi zezicelo zenkqubo yeekhemikhali kwimeko ye-welding.

1.Ukunganyangeki kwe-Corrosion kwisisombululo se-sulfuric acid yayo nayiphi na ingxinano kude kube yi-70℃,izinga lokubola malunga ne-0.1mm/a.
I-2.Izinga le-Corrosion yazo zonke iintlobo ze-concentration hydrochloric acids ayikho phezulu kune-0.1mm / a kwiqondo lokushisa, ngaphantsi kwe-0.5mm / a ukuya kwi-65 ℃.Ukuzaliswa kwe-oksijeni kwi-hydrochloric acid kuchaphazela kakhulu ukuxhatshazwa kwe-corrosion.
3.Izinga lokubola lingaphantsi kwe-0.25mm/a kwi-hydrofluoric acid, lingaphezulu kwe-0.75mm/a kwiimeko ze-55% H3PO4+ 0.8% HF kwiqondo lokushisa elibilayo.
4.Ukunganyangeki kwe-Corrosion ukungxenga i-nitric acid yazo zonke izigxina kwiqondo lobushushu begumbi okanye ubushushu obuphezulu, izinga layo limalunga ne-0.1mm/a, ukuchasana nokutyiwa kakuhle kuzo zonke izigxina ze-chromic acid kunye ne-asidi ephilayo kunye nolunye umxube kude kube ngu-60 ukuya kuma-70 ℃, kwaye izinga lokubola ngaphantsi kwe-0.125mm/a kunye ne-0.175mm/a.
5.Enye yezinto ezimbalwa ezikwaziyo ukumelana neklorini eyomileyo nemanzi, ingasetyenziswa kwiimeko zomhlwa ezitshintshiweyo kwirhasi yeklorini eyomileyo nemanzi.
6.Ukuxhathisa kwirhasi ye-HF yobushushu obuphezulu, izinga lokutya kwerhasi ye-HF yi-0.04mm/a de kube yi-550℃,0.16mm/a de kube yi-750℃.
