Hastelloy C-276® bụ nickel-molybdenum-chromium alloy nwere ezigbo nguzogide corrosion na gburugburu ebe siri ike.Ọdịnaya dị elu nke nickel na molybdenum na-eme ka nickel steel alloy na-eguzogide ọgwụ na mbelata gburugburu ebe chromium na-ebute iguzogide mgbasa ozi oxidizing.Ọ bụ ezie na e nwere ọtụtụ ọdịiche nke Hastelloy nickel alloy, Hastelloy C-276 bụ nke a na-ejikarị eme ihe.
Nchịkọta nke njirimara Hastelloy C-276:
Hastelloy C-276 (N10276) nwere ezigbo nguzogide corrosion na ọtụtụ mgbasa ozi na-emebi emebi n'okpuru ọnọdụ oxidation na mbelata.Nguzogide dị oke mma maka ikpochapụ corrosion, crevice corrosion na nrụgide corrosion cracking.Alloy kwesịrị ekwesị maka ụlọ ọrụ usoro kemịkalụ dị iche iche nwere oxidizing na ibelata mgbasa ozi.Ọdịnaya dị elu nke molybdenum na chromium na-eme ka alloy na-eguzogide corrosion site na ion chloride, na mmewere tungsten na-eme ka nguzogide corrosion ya dịkwuo mma.
Hastelloy C-276 bụ otu n'ime naanị ihe nwere ike iguzogide corrosion nke mmiri chlorine, hypochlorite na chlorine dioxide ngwọta.Alloy nwere nnukwu ihe mgbochi corrosion na-eguzogide ngwọta nnu chlorinated (dị ka Iron chlorinated na ọla kọpa chloride).
