UNS Naj Npawb N 010665
Lwm cov npe uas nrov: Alloy B-2
Hastelloy B 2 yog lub zog txhim kho kom ruaj khov, nickel-molybdenum alloy, nrog qhov kev cuam tshuam tseem ceeb los txo cov chaw ib puag ncig zoo li hydrogen chloride roj, thiab sulfuric, acetic thiab phosphoric acids. Molybdenum yog qhov tseem ceeb alloying uas muab cov kev txhim kho corrosion tseem ceeb los txo cov ib puag ncig. No npib tsib xee hlau alloy tuaj yeem siv rau hauv qhov xwm txheej vim tias nws tawm tsam kev tsim cov lis-ciam av carbide precipitates hauv thaj chaw muaj tshav kub weld.
No npib tsib xee hlau ua haujlwm zoo tiv thaiv hydrochloric acid ntawm txhua qhov kev nkag siab thiab kub. Txuas ntxiv, Hastelloy B 2 muaj qhov ua tau zoo rau pitting, kev nyuaj siab corrosion tawg thiab kom riam-kab thiab thaj tsam kub-cuam tshuam nres. Alloy B 2 muab cov tshuaj tiv thaiv kom tsis txhob muaj cov ntshiab sulfuric acid thiab ntau tus lej tsis-oxidizing kua qaub.
Txheeb Xyuas Qhov Tseem Ceeb ntawm Hastelloy B 2
Alloy B-2 muaj qhov tsis zoo xeb ua rau oxidizingenvironments, yog li ntawd, nws tsis pom zoo rau siv hauv oxidizing media lossis nyob rau hauv muaj cov ntawv xaum lossis kua ntsev vim tias lawv yuav ua rau xeb sai ua ntej. Cov ntsev no yuav pib thaum cov kua hydrochloric acid tawm los rau hauv kev sib cuag nrog hlau thiab tooj. Yog li no, yog tias cov alloy no siv ua ke nrog cov hlau lossis tooj liab xa dej hauv cov kab ke uas muaj cov kua roj hydrochloric acid, lub xub ntiag ntawm cov ntsev no tuaj yeem ua rau lub alloy tsis ua ntej. Ntxiv rau, no nickel steel alloy yuav tsum tsis txhob siv nyob rau qhov kub ntawm 1000 ° F thiab 1600 ° F vim qhov txo qis ntawm cov roj khov hauv cov alloy.
