INCOLOY 825 (UNS N08825 / NS142)
Palapala noi
ʻO Alloy 825 he austenitic nickel-iron-chromium alloy i wehewehe ʻia e nā hoʻohui o ka molybdenum, keleawe a me ka titanium. Ua hoʻomohala ʻia e hāʻawi i ke kūʻē kūʻokoʻa i nā kaiapuni corrosive he nui, ʻelua oxidizing a hoʻemi.
Hoʻokumu ʻia ʻo Alloy 825 e hāʻawi i ke kūʻē kūʻokoʻa i nā kaiapuni corrosive he nui, ʻelua oxidizing a hoʻemi. Me ka pae nickel ma waena o 38%–46%, hōʻike kēia papa i ke kūʻē ʻana i ke koʻikoʻi corrosion cracking (SCC) i hoʻoulu ʻia e nā chlorides a me nā alkalis. Ua lawa ka nickel content no ke kū'ē i ka chloride-ion stress-corrosion cracking. ʻO ka nickel, i hui pū me ka molybdenum a me ke keleawe, hāʻawi pū kekahi i ke kūʻē kūʻokoʻa i ka hōʻemi ʻana i nā kaiapuni e like me nā mea i loaʻa i ka sulfuric a me ka phosphoric acid.
Hāʻawi pū ka mea chromium a me ka molybdenum i ke kūpaʻa pitting maikaʻi ma nā wahi āpau koe wale nō ka hoʻonā chloride oxidizing ikaika. Hoʻohana ʻia ma ke ʻano he mea kūpono i nā ʻano kaʻina hana like ʻole, mālama ka alloy 825 i nā waiwai mechanical maikaʻi mai nā mahana cryogenic a hiki i 1,000 ° F.
ʻO ka hoʻohui ʻana o ka titanium e hoʻopaʻa i ka Alloy 825 e kūʻē i ka sensitization i ke kūlana i hoʻohui ʻia e hana i ka alloy ke kūpaʻa i ka hoʻouka intergranular ma hope o ka ʻike ʻana i nā mahana ma kahi ākea e hoʻonāwaliwali i nā kila kila ʻole. ʻO ka hana ʻana o Alloy 825 ka mea maʻamau o nā nickel-base alloys, me ka mea hiki ke hana a hiki ke weldable e nā ʻano hana like ʻole.
Hiki i kēia mea waiwai ke hoʻohua maikaʻi, ʻano maʻamau o nā ʻāpana nickel-base, e ʻae ana i ka mea e hoʻowili ʻia i nā radii liʻiliʻi loa. ʻAʻole pono ka hoʻopili ʻana ma hope o ke kulou ʻana.
Ua like ia me ka alloy 800 akā ua hoʻomaikaʻi i ke kūpaʻa ʻana i ka ʻino wai. He kūpaʻa maikaʻi loa ia i ka hoʻohaʻahaʻa a me ka oxidizing acids, i ke koʻikoʻi-corrosion māwae, a me ka hoʻouka kūloko e like me ka pitting a me ka corrosion crevice. ʻO Alloy 825 ka mea kū'ē i ka sulfuric a me ka phosphoric acid. Hoʻohana ʻia kēia mea hao nickel no ka hana kemika, nā mea hoʻomalu i ka pollution, ka ʻaila a me ke kinoea punawai paipu, ka hoʻoponopono hou ʻana i ka wahie nuklea, ka hana ʻana i ka waikawa, a me nā mea hana pickling.
