I-Hastelloy B-3 yi-alloy ye-nickel-molybdenum enokumelana okugqwesileyo kwi-pitting, i-corrosion, kunye ne-stress-corrosion cracking plus, ukuzinza kwe-thermal ngaphezu kwe-alloy B-2.Ukongeza, le nickel steel alloy inokumelana okukhulu nohlaselo lwendawo echatshazelwe bubushushu.I-alloy B-3 iphinda imelane ne-sulfuric, i-acetic, i-formic kunye ne-phosphoric acids, kunye nezinye i-media ezingenayo i-oxidizing.Ngaphaya koko, le nickel alloy inokumelana ne-hydrochloric acid kuzo zonke iindawo kunye namaqondo obushushu.I-Hastelloy B-3's isici esahlulayo kukukwazi ukugcina i-ductility egqwesileyo ngexesha lokuvezwa okwethutyana kumaqondo obushushu aphakathi.Ukuvezwa okunjalo kuyenzeka rhoqo ngexesha lonyango lobushushu elihambelana nokwenziwa.
I-alloy B-3 inokumelana ne-corrosion embi kwiindawo ze-oxidizing, ngoko ke, ayikhuthazwa ukuba isetyenziswe kwimidiya ye-oxidizing okanye kubukho be-ferric okanye i-cupric salts ngenxa yokuba inokubangela ukusilela kokukhawuleza kwangaphambi kwexesha.Ezi tyuwa zinokukhula xa i-hydrochloric acid idibana nentsimbi kunye nobhedu.Ngoko ke, ukuba le ngxube yensimbi ye-nickel isetyenziswe ngokubambisana nentsimbi okanye umbhobho wobhedu kwinkqubo equkethe i-hydrochloric acid, ubukho bezi tyuwa bunokubangela ukuba i-alloy ingaphumeleli kwangaphambi kwexesha.

I-alloy ye-Hastelloy B-3 ifanelekile ukusetyenziswa kuzo zonke izicelo ezifuna ukusetyenziswa kwe-Hastelloy B-2 alloy.Njenge-B-2 ingxubevange, i-B-3 ayikhuthazwa ukuba isetyenziswe xa kukho ityuwa ye-ferric okanye i-cupric salts njengoko ezi tyuwa zinokubangela ukungaphumeleli kokutya ngokukhawuleza.Iityuwa ze-ferric okanye ze-cupric zingakhula xa i-hydrochloric acid idibana nentsimbi okanye ubhedu.
