Khoom Taw Qhia
Hastelloy G-30 yog tsim los ntawm UNS N06030 lossis DIN 2.4603. Nws yog cov khoom siv nickel-chromium hlau uas muaj kev tiv thaiv zoo rau phosphoric acid ib puag ncig (cov txheej txheem ntub dej). Hastelloy G30 yog npib tsib xee-raws li kub-kub alloy tsim los ntawm npib tsib xee, chromium, cobalt, tungsten thiab lwm yam khoom, nrog rau cov ntsiab lus npib tsib xee ntawm kwv yees li 37%. Nws kuj tseem muaj qee qhov kev tiv thaiv ib puag ncig corrosion los ntawm chlorides, uas tuaj yeem ua teeb meem hauv qab cov deposits hauv evaporators siv los mloog phosphoric acid. Tsis tas li ntawd, G-30 alloy tsis tshua muaj kev cuam tshuam rau chloride-induced stress corrosion cracking dua stainless hlau. Hastelloy G30 yog nickel-based alloy nrog cov ntsiab lus siab chromium. Nws ua tau zoo dua li lwm cov nickel- thiab hlau-raws li alloys nyob rau hauv ib puag ncig sib xyaw nrog kev lag luam phosphoric acid thiab ntau yam oxidizing acid media xws li nitric / hydrochloric, nitric / hydrofluoric, thiab sulfuric acid. Cov alloy no muaj qhov zoo corrosion kuj. Hastelloy G-30 yog dav siv nyob rau hauv phosphoric acid, sulfuric acid thiab nitric acid ua lag luam, nuclear pipelines, petrochemical thiab chiv industries. G30 alloy tuaj yeem tiv thaiv kev tsim cov qoob loo ciam teb nag lossis daus hauv thaj chaw vuam kub, yog li nws cov khoom siv vuam yog tsim rau ntau yam kev kho tshuaj. Hastelloy G-30 (UNS N06230) yog ib qho kev txhim kho ntawm Ni-Cr-Fe-Mo-Cu Alloy G-3. G-30 muaj ntau dua chromium, cobalt thiab tungsten cov ntsiab lus thiab muaj kev tiv thaiv corrosion zoo dua li lwm cov nickel- thiab hlau-raws li alloys hauv kev lag luam phosphoric acid thiab complex ib puag ncig uas muaj oxidizing acids heev. Lub alloy resists tsim ntawm grain ciam precipitates nyob rau hauv lub tshav kub cuam tshuam cheeb tsam, ua rau nws haum rau feem ntau cov txheej txheem tshuaj siv nyob rau hauv vuam tej yam kev mob.
