Mua: INCOLOY® huila 254Mo/UNS S31254 Aʻe: INCOLOY® huila A286 Nā huahana pili ʻO INCOLOY alloy 825 (UNS N08825) he nickel-iron-chromium alloy me nā hoʻohui o ka molybdenum, keleawe, a me ka titanium. 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 i ke kūʻē kūʻē i ka hoʻohaʻahaʻa ʻana i nā kaiapuni e like me nā mea i loaʻa i ka sulfuric a me ka phosphoric acid. Kōkua ka molybdenum i ke kūʻē ʻana i ka lua a me ka crevice corrosion. Hāʻawi ka ʻike chromium o ka alloy i ke kūʻē ʻana i nā ʻano mea oxidizing like ʻole e like me ka nitric acid, nitrates a me ka paʻakai oxidizing. ʻO ka hoʻohui titanium e lawelawe, me ka mālama wela kūpono, e hoʻopaʻa i ka alloy e kū'ē i ka sensitization i ka corrosion inter granular.
INCOLOY alloys 800H a me 800HT loaʻa i ka ʻoi aku ka kiʻekiʻe o ke kolo a me ka rupture ikaika ma mua o ka INCOLOY alloy 800. ʻO nā mea hoʻohui ʻekolu he ʻaneʻane like nā palena o ka haku melemele.
ʻO 254 SMO ka pahu kila kila, i ʻike ʻia ʻo UNS S31254, i hoʻomohala mua ʻia no ka hoʻohana ʻana i ka wai kai a me nā wahi ʻē aʻe e lawe ana i ka chloride. Ua manaʻo ʻia kēia ʻano he kila kila austenitic kiʻekiʻe loa; Ua kapa pinepine ʻia ʻo UNS S31254 ma ke ʻano he "6% Moly" ma muli o ka molybdenum content; hiki i ka ʻohana 6% Moly ke kū i nā mahana kiʻekiʻe a mālama i ka ikaika ma lalo o nā kūlana volatile.
ʻO INCOLOY alloy A-286 he hao-nickel-chromium alloy me nā hoʻohui o ka molybdenum a me ka titanium. He makahiki-paʻakikī ia no nā waiwai mechanical kiʻekiʻe. Mālama ka alloy i ka ikaika maikaʻi a me ka pale ʻana i ka oxidation ma nā mahana a hiki i 1300 ° F (700 ° C). He austenitic ka alloy ma nā kūlana metallurgical a pau. ʻO ka ikaika kiʻekiʻe a me nā hiʻohiʻona hana maikaʻi loa o INCOLOY alloy A-286 e hoʻohana i ka alloy no nā ʻāpana like ʻole o nā mokulele a me nā turbine kinoea ʻenehana. Hoʻohana ʻia ia no nā noi hoʻopaʻa ʻana i ka ʻenekini kaʻa a me nā ʻāpana like ʻole e pili ana i ke kiʻekiʻe o ka wela a me ke koʻikoʻi a ma ka ʻoihana ʻaila a me ka ʻenehana.
ʻO INCOLOY alloy 800 (UNS N08800) kahi mea i hoʻohana nui ʻia no ke kūkulu ʻana i nā mea pono e koi ana i ka pale ʻana i ka corrosion, ke kūpaʻa wela, ka ikaika, a me ke kūpaʻa no ka lawelawe ʻana a hiki i 1500 ° F (816 ° C). Hāʻawi ʻo Alloy 800 i ke kūpaʻa ʻino maʻamau i nā pāpaʻi wai wai a, ma muli o kāna ʻike o ka nickel, pale i ka pohā ʻino ʻino. Ma nā mahana kiʻekiʻe, hāʻawi ia i ke kū'ē i ka oxidation, carburization, a me ka sulfidation me ka rupture a me ka ikaika kolo. No nā noi e koi ana i ke kūʻē nui ʻana i ke koʻikoʻi ʻoki a me nā kolo, ʻoi aku hoʻi ma nā mahana ma luna o 1500°F (816°C).
