I-Hastelloy B-2 iyisixazululo esiqinile esiqinise ingxube ye-nickel-molybdenum enokumelana okuphawulekayo nokunciphisa izindawo ezifana negesi ye-hydrogen hydride, i-sulfuric acid, i-yanoic acid, ne-phosphoric acid.I-Molybdenum iyisici esiyinhloko se-alloying esinikeza ukumelana nokugqwala okuvelele ekunciphiseni izindawo.Le ingxubevange yensimbi ye-nickel ingasetshenziswa esimweni esishiselwe ngoba imelana nokwakheka kwe-carbide ye-grain boundary precipitates endaweni ethinteke ekushiseni.
Le nickel alloy inikeza ukumelana okuhle kakhulu ne-yan acid ezinhlobonhlobo zokugxila kanye namazinga okushisa.Ngaphezu kwalokho, i-Hastelloy B2 inokumelana okuhle kakhulu nokugoba, ukuqhekeka kokugqwala kwengcindezi, nomugqa wommese nokuhlaselwa kwendawo okuthintekile ukushisa.Ingxubevange B2 ihlinzeka ukumelana ne-sulfuric acid ehlanzekile kanye nama-acid amaningi angenayo i-oxidizing.
Izici ze-Hastelloy B-2
• Ukumelana okuhle kakhulu nokuqhekeka kwe-corrosion kanye ne-pitting
• Ukumelana okuphawulekayo nezimo ezincishisiwe ezifana ne-hydrogen chloride, i-sulfuric acid, i-acetic acid ne-phosphoric acid
• Ingazweli ku-hydrochloric acid kukho konke ukugxila namazinga okushisa
Isicelo se-Hastelloy B-2:
I-Hastelloy B-2 isetshenziswa kabanzi kumakhemikhali, i-petrochemical, ukukhiqizwa kwamandla kanye nezinkambu zokulawula ukungcoliswa kwemvelo, ikakhulukazi ku-sulfuric acid, i-hydrochloric acid, i-phosphoric acid, i-acetic acid nezinye izimboni.
