Paipu Hana ʻOle Kila S32750
Hoʻolauna Huahana
ʻO ke kila kila Super Duplex e like me S32750, he microstructure i hui pū ʻia o ka austenite a me ka ferrite (50/50) i hoʻomaikaʻi i ka ikaika ma luna o nā papa kila ferritic a me austenitic. ʻO ka ʻokoʻa nui, ʻo ia ka nui o ka molybdenum a me ka chromium o Super Duplex e hāʻawi ana i ka mea i ʻoi aku ka nui. Hoʻolaha pū ka chromium kiʻekiʻe i ka hoʻokumu ʻana o nā pae intermetallic maikaʻi ʻole, ka mea i maʻalahi i ka embrittlement 475°C ma muli o ka ua ʻana o ka pae α' waiwai chromium, a i ka embrittlement e sigma, chi a me nā pae ʻē aʻe i nā mahana kiʻekiʻe.
Loaʻa i ka Alloy 2507 (S32750) ka nui o ka naikokene, ʻaʻole wale ia e hoʻolaha i ka hoʻokumu ʻia ʻana o ka austenite a hoʻonui i ka ikaika, akā e hoʻopaneʻe pū i ka hoʻokumu ʻia ʻana o nā pae intermetallic e lawa ai e ʻae i ka hana ʻana a me ka hana ʻana o ka papa duplex.
Hōʻike ʻia ka papa e ke kūpaʻa maikaʻi loa i ka pala chloride, i hui pū ʻia me ka ikaika mechanical kiʻekiʻe loa. He kūpono loa ia no ka hoʻohana ʻana i nā wahi hoʻonāukiuki e like me ka wai kai chlorinated mehana a me nā mea hana i loaʻa ka chloride acidic.
ʻO nā ʻano o ka Alloy 2507 (S32750) penei:
● Kū'ē maikaʻi loa i ka haki ʻana o ka corrosion stress (SCC) i nā wahi e halihali ana i ka chloride
● Kū'ē maikaʻi loa i ka palaho lua a me ka ʻōpala crevice
● Ke kūpaʻa kiʻekiʻe i ka palaho maʻamau
● Ikaika mīkini kiʻekiʻe loa
● Nā waiwai kino e hāʻawi ana i nā pono hoʻolālā
● Ke kūpaʻa kiʻekiʻe i ka palaho a me ka luhi o ka palaho
● Maikaʻi ka hiki ke hoʻopili ʻia
Ua hoʻolālā ʻia ʻo S32750 no nā noi koi e pono ai ka ikaika kūikawā a me ke kūpaʻa i ka pala, i loaʻa makaʻina hana kemika, nā lako petrochemical, a me ka wai kai. Hoʻohana nui ʻia ia i ka ʻimi ʻana/hana ʻana i ka ʻaila a me ke kinoea ma waho o ke kai a me nā mea hoʻololi wela i ka hana petrochemical/kemika. He kūpono hoʻi ke ʻano no nā noi hydraulic a me nā mea hana ma nā wahi kai tropical.
