S32750 ʻAi Kuhili ʻole ʻia ʻole

ʻO ka wehewehe pōkole:

ʻO Alloy 2507, me ka helu UNS S32750, he ʻelua-phase alloy ia e pili ana i ka ʻōnaehana hao-chromium-nickel me kahi ʻano hui like ʻole o ka austenite a me ka ferrite. Ma muli o ke kaulike duplex phase, hōʻike ʻo Alloy 2507 i ke kūpaʻa maikaʻi loa i ka ʻino maʻamau e like me nā kila stainless austenitic me nā mea hoʻohui like. Ma waho aʻe, loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka ikaika o ka chloride SCC ʻoi aku ka maikaʻi ma mua o kona mau hoa austenitic ʻoiai e mālama ana i ka paʻakikī o ka hopena ma mua o nā hoa ferritic.

ʻO ka Super Duplex stainless e like me S32750, he microstructure hui ʻia o austenite a me ferrite (50/50) i hoʻomaikaʻi i ka ikaika ma luna o nā māka kila ferritic a me austenitic. ʻO ka ʻokoʻa nui ʻo ia ka Super Duplex he molybdenum kiʻekiʻe a me ka chromium maʻiʻo e hāʻawi i ka mea i ʻoi aku ka nui o ka chromium kiʻekiʻe e hoʻoikaika i ka hoʻokumu ʻana i nā pae intermetallic detrimental, i maʻalahi i ka embrittlement 475 ° C ma muli o ka ua o ka chromium-rich α' phase, a me ka embrittlement e ka sigma, chi a me nā ʻāpana ʻē aʻe i nā wela kiʻekiʻe.

ʻO Alloy 2507 (S32750) ka mea i ʻoi aku ka nui o ka nitrogen, ʻaʻole ia e hoʻoikaika i ka hoʻokumu ʻana o ka austenite a hoʻonui i ka ikaika, akā hoʻopaneʻe hoʻi i ka hoʻokumu ʻana o nā ʻāpana intermetallic e hiki ai ke hana a hana i ka papa duplex.

Hōʻike ʻia ka papa e ka maikaʻi loa o ka chloride corrosion resistance, i hui pū ʻia me ka ikaika mechanical kiʻekiʻe. He kūpono loa ia no ka hoʻohana ʻana i nā kaiapuni koʻikoʻi e like me ka wai kai chlorinated mehana a me ka media chloride acidic.

ʻO nā hiʻohiʻona Alloy 2507 (S32750) penei:

● Kūʻē maikaʻi loa i ke koʻikoʻi ʻana o ka corrosion cracking (SCC) ma nā kaiapuni chloride
● Kūʻē maikaʻi i ka lua a me ka ʻawaʻawa
● Kū'ē kiʻekiʻe i ka corrosion maʻamau
● Kiʻekiʻe loa mechanical ikaika
● Nā waiwai kino e hāʻawi ana i nā pono hoʻolālā
● Kū'ē kiʻekiʻe i ka erosion corrosion a me ka corrosion luhi
● maikaʻi weldability

Hoʻolālā ʻia ʻo S32750 no nā noi koi e koi ana i ka ikaika ʻokoʻa a me ke kūpaʻa corrosion, i loaʻa makaʻina hana kemika, petrochemical, a me nā lako wai kai. Hoʻohana nui ʻia ia i ka ʻimi ʻana i ka ʻaila a me ke kinoea / hana a me nā mea hoʻololi wela i ka hana petrochemical / kemika. He kūpono hoʻi ka papa no nā noi hydraulic a me nā mea kani i nā kaiapuni kai moana.
