Amabha ayindilinga ensimbi ayindilinga ashisayo e-B2

I-Hastelloy B2 iyisixazululo esiqinile esiqinisiwe, i-nickel-molybdenum alloy, enokumelana okuphawulekayo nokunciphisa izindawo ezifana negesi ye-hydrogen chloride, ne-sulfuric, acetic kanye ne-phosphoric acid. I-Molybdenum iyingxenye eyinhloko ye-alloying ehlinzeka ngokuphawulekayo ukumelana nokugqwala ekunciphiseni izindawo. Le ingxubevange yensimbi ye-nickel ingasetshenziswa esimweni esihlanganisiwe ngenxa yokuthi imelana nokwakheka kwe-carbide ye-grain-boundary precipitates endaweni ethintekile ukushisa kwe-weld.Le nickel alloy inikeza ukumelana okuhle kakhulu ku-hydrochloric acid kukho konke ukugxila namazinga okushisa. Ukwengeza, i-Hastelloy B2 inokumelana okuhle kakhulu nokugoba, ukuqhekeka kokugqwala kwengcindezi kanye nokuhlasela komugqa wommese kanye nokuhlaselwa kwendawo ethinteke ukushisa. Ingxubevange B2 ihlinzeka ukumelana ne-sulfuric acid emsulwa kanye nenani lama-asidi angewona oxidizing.

Ingxubevange B-2 inokumelana nokugqwala okungekuhle ku-oxidizingenvironment, ngakho-ke, ayinconywa ukuthi isetshenziswe emithonjeni ye-oxidizing noma lapho kukhona usawoti we-ferric noma we-cupric ngoba ingabangela ukwehluleka ukugqwala ngokushesha ngaphambi kwesikhathi. Lawa masawoti angase athuthuke lapho i-hydrochloric acid ihlangana nensimbi nethusi. Ngakho-ke, uma le-alloy isetshenziswa kanye ne-iron noma ipayipi yethusi ohlelweni oluqukethe i-hydrochloric acid, ukuba khona kwalawa sawoti kungabangela ukuthi i-alloy ihluleke ngaphambi kwesikhathi. Ngaphezu kwalokho, le ngxubevange yensimbi ye-nickel akufanele isetshenziswe emazingeni okushisa aphakathi kuka-1000° F kanye no-1600° F ngenxa yokuncipha kwe-ductility ku-alloy.
