Hastelloy B 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 qhov tseem ceeb ntawm cov khoom siv alloying uas muab kev tiv thaiv corrosion tseem ceeb rau kev txo qis ib puag ncig. Cov nickel steel alloy no tuaj yeem siv tau rau hauv qhov chaw 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.
Cov nickel alloy no muab kev tiv thaiv zoo rau hydrochloric acid ntawm txhua qhov ntau thiab kub. 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 B muab kev tiv thaiv rau cov ntshiab sulfuric acid thiab ib tug xov tooj ntawm non-oxidizing acids.
