HastelloyC alloy bụ Ni-Cr-Molybdenum-Tungsten alloy nke na-enye nguzogide corrosion ka mma karịa Ni-Cr-Molybdenum-Hastelloy C276,C4 na 625 alloys.
Hastelloy C alloys nwere ezigbo nguzogide nbibi, nrụrụ na-emebi emebi na mgbawa corrosion nrụgide.
Ọ nwere ezigbo nguzogide oxidizing mmiri mgbasa ozi, gụnyere mmiri chlorine, nitric acid ma ọ bụ ngwakọta nke oxidizing acid nwere chloride ion.
N'otu oge ahụ, Hastelloy C alloys nwekwara ikike dị mma iguzogide mbelata na gburugburu oxidizing zutere n'oge usoro ahụ.
Site na ngbanwe a, enwere ike iji ya na mpaghara ụfọdụ nwere nsogbu, ma ọ bụ n'ụlọ ọrụ maka ebumnuche mmepụta dị iche iche.
Hastelloy C alloy nwere nguzogide pụrụ iche na gburugburu kemịkalụ dị iche iche, gụnyere ihe ndị na-egbu egbu siri ike, dị ka ferric chloride, ọla kọpa chloride, chlorine, ngwọta mmetọ ikuku (organic ma ọ bụ inorganic), formic acid, acetic acid, acetic anhydride, mmiri mmiri na nnu ngwọta.
Hastelloy C alloy nwere ikike iguzogide oke ọdịda ọka na mpaghara ọkụ ịgbado ọkụ, nke na-eme ka ọ dabara maka ọtụtụ ụdị ngwa kemịkalụ kemịkalụ na steeti ịgbado ọkụ.
