Dab tsi yog npib tsib xee alloy 600 thiab Hastelloy C276 raj?
Inconel 600 thiab Hastelloy C276 tubing yog siab -kev ua tau zoo nickel- cov tubing muaj npe nrov rau lawv lub zog tshwj xeeb thiab kev tiv thaiv corrosion nyob rau hauv huab cua txias. Inconel 600 ua tau zoo heev nyob rau hauv siab - qhov kub thiab txias qhov chaw, thaum C276 nthuav tawm ntau dua rau corrosive, oxidizing, thiab chloride- nplua nuj tawm (xws li cov chlorine ntub dej thiab dej hiav txwv). Qhov sib txawv tseem ceeb yog nyob rau hauv lawv cov muaj pes tsawg leeg (C276 muaj qhov siab molybdenum / chromium piv, thaum Inconel 600 yog npib tsib xee{12}}chromium alloy) thiab cov kev xav tau tshwj xeeb. Qhov no ua rau C276 zoo tagnrho rau kev ua tshuaj, thaum Inconel 600 haum rau aerospace / nuclear daim ntaub ntawv, txawm hais tias ob leeg muaj peev xwm tswj tau qhov kev thov siab - kub, siab - cov ntawv thov siab zoo.
Qhov kub ntawm INCONEL 600 alloy yog dab tsi?
INCONEL 600 alloy muaj ntau yam kev siv thiab tuaj yeem siv tau ntawm qhov kub thiab txias xws li qhov kub thiab txias mus rau 2000℃F (1095 degree). Vim nws lub zog siab thiab corrosion kuj, cov hlau no tau siv dav hauv kev lag luam tshuaj.
Inconel 600 yeeb nkab yog dab tsi?
Inconel 600 yeeb nkab yog ib hom yeeb nkab ua los ntawm high -kev ua tau zoo nickel-chromium- hlau alloy (Inconel 600), tshwj xeeb tsim los rau kev thauj cov xov xwm hauv qhov kub siab heev - kub thiab corrosive ib puag ncig (xws li chlorides, alkalis, thiab ntau yam kua qaub) 1150 degree. Nrog nws zoo heev - kub lub zog, oxidation tsis kam, thiab tsis kam mus rau kev nyuaj siab corrosion cracking, nws yog dav siv nyob rau hauv cov chaw tseem ceeb xws li nuclear fais fab nroj tsuag chav generators, petrochemical cracking furnaces, cov khoom siv kho cua sov, thiab hnyav txheej txheem. Nws yog ib qho saum toj kawg nkaus -tier, txhim khu kev qha kev daws teeb meem thaum stainless hlau tsis txaus, tab sis ntawm tus nqi siab dua.
C276 alloy yeeb nkab yog dab tsi?
C276 alloy yeeb nkab muaj molybdenum siab thiab chromium cov ntsiab lus, ua kom nws tiv taus chloride ion corrosion; qhov sib ntxiv ntawm tungsten ntxiv txhim kho nws cov corrosion kuj. Cov khoom no yog tshwj xeeb tshaj yog haum rau high - ib puag ncig kub, sib xyaw corrosive ib puag ncig ntawm inorganic thiab organic acids (xws li formic acid thiab acetic acid), thiab corrosive seawater ib puag ncig.
