Hastelloy B2 UNS N10665/W.Nr.2.4617

ʻO ka wehewehe pōkole:

ʻO Hastelloy B2 kahi hopena paʻa i hoʻoikaika ʻia, nickel-molybdenum alloy, me ke kūʻē nui ʻana i ka hōʻemi ʻana i nā kaiapuni e like me ke kinoea hydrogen chloride, a me ka sulfuric, acetic a me ka phosphoric acid. ʻO Molybdenum ka mea hoʻohui mua e hāʻawi i ke kūpaʻa corrosion koʻikoʻi i ka hōʻemi ʻana i nā kaiapuni. Hiki ke hoʻohana ʻia kēia mea hao nickel i loko o ke kūlana as-welded no ka mea e kūʻē i ka hoʻokumu ʻia ʻana o nā carbide palena o ka palaoa i loko o ka weld wela.

Hāʻawi kēia nickel alloy i ke kūpaʻa maikaʻi loa i ka waika hydrochloric ma nā ʻano a me nā mahana. Eia hou, ua kū maikaʻi loa ʻo Hastelloy B2 i ka pitting, stress corrosion cracking a me ka hoʻouka kaua ʻana i ka laina pahi a me ka wela. Hāʻawi ka Alloy B2 i ke kū'ē i ka waikawa sulfuric maʻemaʻe a me ka nui o nā waikawa non-oxidizing.
