ʻO Hastelloy B-2 kahi hopena paʻa i hoʻoikaika ʻia i ka nickel-molybdenum alloy me ke kūʻē kūʻē i ka hoʻohaʻahaʻa ʻana i nā kaiapuni e like me ka hydrogen hydride gas, sulfuric acid, yanoic acid, a me phosphoric acid.ʻO Molybdenum ka mea hoʻohui nui e hāʻawi i ke kūpaʻa corrosion koʻikoʻi i ka hōʻemi ʻana i nā kaiapuni.Hiki ke hoʻohana ʻia kēia huila nickel-steel i ke kūlana welded no ka mea e kūʻē i ka hoʻokumu ʻana o ka palena o ka palaoa carbide precipitates i ka weld wela wela.
Hāʻawi kēia nickel alloy i ke kūpaʻa maikaʻi loa i ka waikawa yan ma kahi ākea o ka ʻike a me nā mahana.Eia kekahi, ʻoi aku ka maikaʻi o ka Hastelloy B2 i ka pitting, stress corrosion cracking, a me ka laina pahi a me nā hoʻouka kaua wela.Hāʻawi ʻo Alloy B2 i ke kūʻē i ka waikawa sulfuric maʻemaʻe a me ka nui o nā waikawa non-oxidizing.
Nā hiʻohiʻona o Hastelloy B-2
• Kūleʻa maikaʻi loa i ke koʻikoʻi i ka pohā a me ka lua
• Ke kū'ē kupaianaha i ka ho'ēmiʻana i nā kūlana e like me ka hydrogen chloride, sulfuric acid, acetic acid a me ka phosphoric acid
• Kūleʻa i ka waika hydrochloric ma nā ʻano a me nā mahana a pau
Palapala noi Hastelloy B-2:
Hoʻohana nui ʻia ʻo Hastelloy B-2 i nā kemika, petrochemical, hana mana a me nā kahua hoʻomalu haumia, ʻoi aku ka nui o ka sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid a me nā ʻoihana ʻē aʻe.
