Hastelloy B-2 ndi njira yolimba yomwe imalimbitsa nickel-molybdenum alloy ndi kukana modabwitsa kuchepetsa malo monga mpweya wa hydrogen hydride, sulfuric acid, yanoic acid, ndi phosphoric acid.Molybdenum ndiye gawo lalikulu la alloying lomwe limapereka kukana kwa dzimbiri pakuchepetsa malo.Chitsulo cha nickel-chitsulo ichi chitha kugwiritsidwa ntchito ngati chowotcherera chifukwa chimakana kupanga ma carbide amtundu wa tirigu m'dera lomwe limakhudzidwa ndi kutentha.
Nickel alloy iyi imapereka kukana kwa asidi yan mumitundu yosiyanasiyana komanso kutentha.Kuphatikiza apo, Hastelloy B2 ili ndi kukana kwabwino kwambiri pakubowola, kusweka kwa dzimbiri, ndi mzere wa mpeni komanso kutentha komwe kumakhudzidwa ndi madera.Aloyi B2 imapereka kukana koyera sulfuric acid ndi ma acid ambiri omwe si oxidizing.
Zithunzi za Hastelloy B-2
• Zabwino kwambiri kukana kupsinjika kwa dzimbiri kung'aluka ndi pitting
• Kukana kodabwitsa pakuchepetsa zinthu monga hydrogen chloride, sulfuric acid, acetic acid ndi phosphoric acid.
• Kugonjetsedwa ndi hydrochloric acid pamtundu uliwonse ndi kutentha
Ntchito ya Hastelloy B-2:
Hastelloy B-2 amagwiritsidwa ntchito kwambiri mu mankhwala, petrochemical, kupanga mphamvu ndi kuwononga minda, makamaka sulfuric acid, hydrochloric acid, asidi phosphoric, asidi asidi ndi mafakitale ena.
