HastelloyC alloy inoshandiswa zvakasiyana-siyana Ni-Cr-Molybdenum-Tungsten alloy inopa zvirinani zvakazara corrosion kuramba pane imwe iripo Ni-Cr-Molybdenum-Hastelloy C276, C4 uye 625 alloys.
Hastelloy C alloys ane yakanakisa kuramba kugomba, crevice corrosion uye kusagadzikana ngura kutsemuka.
Iyo ine yakanakisa kuramba kune oxidizing midhiya yemvura, inosanganisira wet chlorine, nitric acid kana musanganiswa weoxidizing acids ine chloride ions.
Panguva imwecheteyo, Hastelloy C alloys anewo kugona kwakaringana kurwisa kudzikisira uye oxidizing nharaunda dzakasangana panguva yekuita.
Nekusiyana-siyana uku, inogona kushandiswa mune dzimwe nzvimbo dzinonetsa, kana mumafekitori kune zvakasiyana siyana zvekugadzira.
Hastelloy C alloy ine kupikisa kwakasiyana-siyana kumamiriro emakemikari akasiyana-siyana, kusanganisira yakasimba oxidizing zvinhu, zvakadai seferric chloride, copper chloride, chlorine, thermal pollution solution (organic kana inorganic), formic acid, acetic acid, acetic anhydride, mvura yegungwa uye munyu.
Hastelloy C alloy inokwanisa kurwisa zviyo muganho wekunaya kwemvura munzvimbo yewelding inopisa yakakanganiswa nzvimbo, iyo inoita kuti ive yakakodzera kune akawanda marudzi emakemikari mashandisirwo ekushandiswa munzvimbo yekupisa.
