I-Hastelloy B iyisisombululo esiqinileyo esomeleziweyo, i-nickel-molybdenum alloy, kunye nokuchasana okuphawulekayo ekunciphiseni iimeko ezifana negesi ye-hydrogen chloride, kunye ne-sulfuric, i-acetic kunye ne-phosphoric acid. I-Molybdenum yeyona nto iphambili ye-alloying enika ukuxhathisa okubalulekileyo kokutya ekunciphiseni okusingqongileyo. Le nickel steel alloy ingasetyenziselwa kwimeko ye-welded ngenxa yokuba ichasene nokubunjwa kwe-grain-boundary carbide precipitates kwindawo echaphazelekayo ukushisa kwe-weld.
Le nickel alloy inika ukuxhathisa okugqwesileyo kwi-hydrochloric acid kuzo zonke izigxina kunye namaqondo obushushu. Ukongeza, i-Hastelloy B2 inokumelana okugqwesileyo kwi-pitting, i-corrosion cracking yoxinzelelo kunye nokuhlaselwa kwe-melane kunye nokuhlaselwa kwendawo echaphazelekayo. I-alloy B inika ukuxhathisa kwi-asidi ye-sulfuric ecocekileyo kunye nenani le-non-oxidizing acids.
