Hastelloy C-4
Hastelloy C-4 (N06455) Hastelloy yog austenitic low-carbon nickel-molybdenum-chromium alloy. Qhov sib txawv tseem ceeb ntawm Nicrofer6616hMo thiab lwm yam ua ntej-tsim alloys ntawm cov tshuaj zoo sib xws yog cov pa roj carbon tsawg, silicon, hlau, thiab cov ntsiab lus tungsten. Xws li cov tshuaj muaj pes tsawg leeg tso cai rau nws muaj kev ruaj ntseg zoo ntawm 650-1040 degree, txhim kho kev tiv thaiv rau intergranular corrosion thiab tsis txhob ntug kab corrosion susceptibility thiab weld tshav kub-cuam tshuam cheeb tsam corrosion nyob rau hauv tsim raug tej yam kev mob. Cov ntsiab lus molybdenum thiab chromium siab dua ua rau Hastelloy C-4 alloy tiv thaiv ntau yam tshuaj lom neeg, suav nrog txo cov xov xwm xws li phosphoric acid, hydrochloric acid, sulfuric acid, chlorine, thiab organic lossis inorganic chlorine-muaj cov xov xwm. Vim muaj cov ntsiab lus npib tsib xee siab, Hastelloy C{11}} muaj txiaj ntsig zoo hauv kev tiv thaiv kev ntxhov siab corrosion vim yog cov tshuaj chlorine, txawm tias hauv cov tshuaj chloride kub.
