Hastelloy B2 yog ib qho kev daws teeb meem ntxiv dag zog, npib tsib xee-molybdenum alloy, nrog kev tiv thaiv tseem ceeb los txo qhov chaw xws li hydrogen chloride gas, thiab sulfuric, acetic thiab phosphoric acids. Molybdenum yog lub ntsiab alloying uas muab kev tiv thaiv corrosion tseem ceeb los txo qhov chaw. Cov npib tsib xee hlau no tuaj yeem siv rau hauv qhov zoo li-welded vim tias nws tiv thaiv kev tsim ntawm cov qoob loo ntawm cov ciam teb carbide precipitates nyob rau hauv qhov chaw weld tshav kub-cuam tshuam. Tsis tas li ntawd, Hastelloy B2 muaj kev tiv thaiv zoo heev rau pitting, kev nyuaj siab corrosion cracking thiab rau riam-kab thiab tshav kub-tshem tawm tsam. Alloy B2 muab kev tiv thaiv rau cov ntshiab sulfuric acid thiab ib tug xov tooj ntawm non-oxidizing acids.
Alloy B-2 tsis zoo corrosion kuj rau oxidizingenvironments, yog li ntawd, nws tsis pom zoo siv rau hauv oxidizing media los yog nyob rau hauv lub xub ntiag ntawm ferric los yog cupric ntsev vim hais tias lawv yuav ua rau sai sai corrosion tsis ua hauj lwm. Cov ntsev no tuaj yeem txhim kho thaum hydrochloric acid los ntawm kev sib cuag nrog hlau thiab tooj liab. Yog li ntawd, yog tias cov hlau no siv nrog cov hlau lossis tooj liab kav hauv lub cev uas muaj hydrochloric acid, qhov muaj cov ntsev no tuaj yeem ua rau cov hlau tsis ua haujlwm ntxov. Tsis tas li ntawd, cov nickel hlau alloy no yuav tsum tsis txhob siv ntawm qhov kub ntawm 1000 ° F thiab 1600 ° F vim tias qhov txo qis hauv cov ductility hauv cov hlau.Qhov ntom | 9.2g 3 |
