Hastelloy B2 ni igisubizo gikomeye gishimangirwa, nikel-molybdenum ivanze, hamwe no kurwanya cyane kugabanya ibidukikije nka gaze ya hydrogène ya chloride, na acide sulfurike, acetike na fosifori. Molybdenum nikintu cyibanze kivanze gitanga ruswa ikomeye yo kugabanya ibidukikije. Iyi nikel ya nikel irashobora gukoreshwa muburyo bwo gusudira kuko irwanya ishyirwaho ryimvura ya karbide igabanya imipaka muri zone yibasiwe nubushyuhe.
Iyi nikel alloy itanga imbaraga nziza zo kurwanya aside hydrochloric kuri concentration zose hamwe nubushyuhe. Hiyongereyeho, Hastelloy B2 ifite imbaraga zo kurwanya ibinogo, gucika intege no gucika ku cyuma ndetse no kwibasirwa na zone. Alloy B2 itanga imbaraga zo kurwanya aside irike ya sulfurike na acide nyinshi zidafite aside.
