Hastelloy C-276 kev tshuaj xyuas cov khoom xyaw
C-276 Hastelloy yog npib tsib xee-molybdenum-chromium-hlau-tungsten npib tsib xee-raws li alloy thiab yog corrosion-resistant tshaj plaws ntawm cov ntaub ntawv hlau niaj hnub. Feem ntau resistant rau cov chlorine ntub dej, ntau yam oxidizing chlorides, chloride ntsev daws, sulfuric acid thiab oxidizing ntsev, thiab muaj corrosion kuj zoo nyob rau hauv qis thiab nruab nrab kub hydrochloric acid. Yog li ntawd, nyob rau hauv peb caug xyoo dhau los, nws tau dav siv nyob rau hauv hnyav corrosive ib puag ncig, xws li tshuaj lom neeg kev lag luam, petrochemical kev lag luam, flue roj desulfurization, pulp thiab ntawv ua, ib puag ncig tiv thaiv thiab lwm yam kev lag luam teb.Qhov ntau yam corrosion ntaub ntawv ntawm Hastelloy C{ {7}} alloy yog ib yam, tab sis lawv tsis tuaj yeem siv raws li cov lus qhia tshwj xeeb, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig tsis paub, thiab cov ntaub ntawv yuav tsum raug xaiv tom qab kuaj. Tsis muaj Cr txaus hauv Hastelloy C-276 alloy los tiv thaiv corrosion hauv qhov chaw muaj zog oxidizing, xws li kub concentrated nitric acid. Kev tsim cov hlau no feem ntau yog rau cov txheej txheem tshuaj lom neeg ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv muaj cov kua qaub sib xyaw, xws li cov yeeb nkab tawm ntawm flue gas desulfurization systems.
Hastelloy C-276 kev ua tau zoo
Cov hlau muaj kev tiv thaiv zoo heev rau feem ntau cov xov xwm corrosive hauv ob qho tib si oxidized thiab txo cov xeev. Zoo heev tiv taus pitting corrosion, crevice corrosion thiab kev nyuaj siab corrosion cracking. Alloys yog tsim rau siv nyob rau hauv ntau yam kev lag luam chemical industries uas muaj oxidizing thiab txo cov xov xwm. C276 high-temperature alloy sheet muaj cov ntsiab lus molybdenum thiab chromium siab, uas ua rau cov hlau tsis muaj chloride ion yaig. Lub caij tungsten kuj tseem txhim kho nws cov corrosion kuj.
