I-Hastelloy B-2 sisisombululo esiqinileyo esomeleza i-nickel-molybdenum alloy kunye nokuchasana okuphawulekayo ekunciphiseni iimeko ezifana negesi ye-hydrogen hydride, i-sulfuric acid, i-yanoic acid, kunye ne-phosphoric acid.I-Molybdenum yeyona nto iphambili ye-alloying ebonelela ngokumelana nokugqwesa okubalaseleyo ekunciphiseni okusingqongileyo.Le nickel-steel alloy ingasetyenziselwa kwi-welded condition kuba ixhathisa ukubunjwa kwe-grain boundary carbide precipitates kwindawo echaphazelekayo ukushisa kwe-weld.
Le nickel alloy inika ukuxhathisa okugqwesileyo kwi-asidi yan kuluhlu olubanzi lokugxila kunye namaqondo obushushu.Ukongeza, iHastelloy B2 inokumelana okugqwesileyo kwi-pitting, i-corrosion cracking yoxinzelelo, kunye nomgca wemela kunye nobushushu obuchaphazela ukuhlaselwa kwendawo.I-alloy B2 inika ukuxhathisa kwi-asidi ye-sulfuric ecocekileyo kunye nee-acids ezininzi ezingenayo i-oxidizing.
Iimpawu zeHastelloy B-2
• Ukumelana kakuhle kakhulu noxinzelelo lokuqhekeka komhlwa kunye nokugqobhoza
• Ukuxhathisa okumangalisayo kwiimeko zokunciphisa ezifana ne-hydrogen chloride, i-sulfuric acid, i-acetic acid kunye ne-phosphoric acid.
• Ukumelana ne-hydrochloric acid kuzo zonke iindawo kunye namaqondo obushushu
Isicelo seHastelloy B-2:
I-Hastelloy B-2 isetyenziswa ngokubanzi kwiikhemikhali, i-petrochemical, imveliso yamandla kunye nemimandla yokulawula ukungcola, ngakumbi kwi-asidi ye-sulfuric, i-hydrochloric acid, i-phosphoric acid, i-acetic acid kunye namanye amashishini.
