B2 intsimbi eshushu eqengqelekayo imivalo engqukuva

I-Hastelloy B2 isisombululo esiqinileyo esomeleziweyo, i-nickel-molybdenum alloy, kunye nokuchasana okuphawulekayo ekunciphiseni imimandla efana negesi ye-hydrogen chloride, kunye ne-sulfuric, i-acetic kunye ne-phosphoric acids. I-Molybdenum yeyona nto iphambili ye-alloying enika ukuxhathisa okubalulekileyo kokutya ekunciphiseni okusingqongileyo. Le ingxubevange yentsimbi nickel ingasetyenziswa kwimeko njengoko-welding kuba ukumelana ukubunjwa okuziinkozo-umda carbide precipitates kwi weld echaphazelekayo ubushushu zone.Le nickel ingxubevange inika ukuchasana obalaseleyo 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 kwindawo echatshazelwe bubushushu. I-alloy B2 inika ukuchasana ne-asidi ye-sulfuric ecocekileyo kunye nenani le-non-oxidizing acids.

I-alloy B-2 inokumelana ne-corrosion embi kwi-oxidizingenvironments, ngoko ke, ayikhuthazwa ukuba isetyenziswe kwi-oxidizing media okanye kubukho be-ferric okanye i-cupric salts kuba inokubangela ukusilela kokukhawuleza kwangaphambi kwexesha. Ezi tyuwa zinokukhula xa i-hydrochloric acid idibana nentsimbi kunye nobhedu. Ngoko ke, ukuba le ngxube isetyenziswe ngokubambisana nentsimbi okanye ipayipi yobhedu kwinkqubo equkethe i-hydrochloric acid, ubukho bezi tyuwa bunokubangela ukuba i-alloy ingaphumeleli kwangaphambi kwexesha. Ukongeza, le nickel steel alloy akufanele isetyenziswe kumaqondo obushushu phakathi kwe-1000 ° F kunye ne-1600 ° F ngenxa yokunciphisa i-ductility kwi-alloy.
