Hastelloy B ndi njira yolimba yolimbitsidwa, nickel-molybdenum alloy, yokhala ndi kukana kwambiri kuchepetsa malo monga mpweya wa hydrogen chloride, ndi sulfuric, acetic ndi phosphoric acid. Molybdenum ndiye gawo loyamba la alloying lomwe limapereka kukana kwa dzimbiri pakuchepetsa malo. Chitsulo cha nickel chitsulo ichi chingagwiritsidwe ntchito ngati chowotcherera chifukwa chimakana kupanga mapangidwe a carbide amtundu wa tirigu m'madera omwe amakhudzidwa ndi kutentha.
Nickel alloy iyi imapereka kukana kwa hydrochloric acid pamlingo uliwonse komanso kutentha. Kuphatikiza apo, Hastelloy B2 ili ndi kukana kwabwino kwambiri pakubowola, kusweka kwa dzimbiri komanso kuukira kwa mipeni komanso kukhudzidwa ndi kutentha. Aloyi B amapereka kukana koyera sulfuric acid ndi angapo non-oxidizing zidulo.
