ʻO INCOLOY 825 (UNS N08825 / NS142)
Noi
ʻO Alloy 825 kahi alloy nickel-iron-chromium austenitic i wehewehe ʻia e ka hoʻohui ʻana o ka molybdenum, keleawe a me ka titanium. Ua hoʻomohala ʻia e hāʻawi i ke kū'ē kūikawā i nā ʻano ʻino he nui, ʻo ia hoʻi ka oxidizing a me ka reduction.
Ua hoʻomohala ʻia ʻo Alloy 825 e hāʻawi i ke kūʻē kūikawā i nā ʻano ʻino he nui, ʻo ia hoʻi ka oxidizing a me ka hoʻemi ʻana. Me ka pae o ka nickel ma waena o 38% –46%, hōʻike kēia papa i ke kūʻē koʻikoʻi i ka stress corrosion cracking (SCC) i hoʻokumu ʻia e nā chlorides a me nā alkalis. Ua lawa ka nui o ka nickel no ke kūʻē ʻana i ka chloride-ion stress-corrosion cracking. ʻO ka nickel, me ka molybdenum a me ke keleawe, hāʻawi pū i ke kūʻē koʻikoʻi i nā ʻano ʻino e like me nā mea i loaʻa nā waikawa sulfuric a me phosphoric.
Hāʻawi pū ka ʻike chromium a me molybdenum i ke kūpaʻa maikaʻi o ka pitting ma nā wahi āpau koe wale nō nā hopena chloride oxidizing ikaika. Hoʻohana ʻia ma ke ʻano he mea pono i nā ʻano hana like ʻole, mālama ka alloy 825 i nā waiwai mechanical maikaʻi mai nā mahana cryogenic a hiki i ka 1,000° F.
ʻO ka hoʻohui ʻana o ka titanium e hoʻopaʻa i ka Alloy 825 e kūʻē i ka sensitization i ke kūlana as-welded e hana ana i ka alloy e kūʻē i ka hoʻouka intergranular ma hope o ka hōʻike ʻana i nā mahana ma kahi pae e sensitize i nā kila kila i hoʻopaʻa ʻole ʻia. ʻO ka hana ʻana o Alloy 825 he mea maʻamau ia o nā alloys nickel-base, me nā mea i maʻalahi ke hana a me ka weldable e nā ʻano hana like ʻole.
He maikaʻi loa ke ʻano o kēia mea, maʻamau o nā hui nickel-base, e ʻae ana i ka mea e pelu ʻia i nā radii liʻiliʻi loa. ʻAʻole pono ka hoʻoheheʻe ʻana ma hope o ke pelu ʻana.
Ua like ia me ka hui hao 800 akā ua hoʻomaikaʻi ʻia kona kūpaʻa i ka palaho wai. Loaʻa iā ia ke kūpaʻa maikaʻi loa i nā waikawa hoʻemi a me ka oxidizing, i ka haki ʻana o ka stress-corrosion, a me ka hoʻouka kaua kūloko e like me ka pitting a me ka crevice corrosion. He kūpaʻa loa ka hui hao 825 i nā waikawa sulfuric a me phosphoric. Hoʻohana ʻia kēia hui hao nickel no ka hana kemika, nā lako kaohi haumia, nā paipu lua wai aila a me ke kinoea, ka hana hou ʻana i ka wahie nukelea, ka hana ʻakika, a me nā lako pickling.
