| Inoa mea kūʻai | 2205,2705,2101,2304,1805; |
| Hōʻike huahana | Mānoanoa 2.0 ~ 60mm, laula 1500 ~ 2500mm; |
| Hoʻohana huahana | No ka hana pepa, ka petrochemical, ka hana moku, ka mana nuklea, ka moku kaomi, ka desalination o ke kai, ka paila wai, ka halihali ana, ka hana mīkini, ka hoomalu ana i ke kaiapuni, ka ipuhao a me na oihana e ae; |
| Nā hiʻohiʻona huahana | Nui nā ʻano, nā kikoʻī piha, ka hana ʻoi aku ka maikaʻi, ka hoʻohana ākea, ua loaʻa i nā ʻano like ʻole o ka ʻoihana pili; |
| Hana huahana | ʻO ka ikaika kiʻekiʻe, ʻoi aku ka ikaika o ka 18-8 stainless steel, maikaʻi ka pore corrosion kūpaʻa a me ka chloride stress corrosion kū'ē, kuʻiʻo thermal māwae liʻiliʻi, nui thermal conductivity, liʻiliʻi laina hoʻonui coefficient, conducive i ka hana paakiki, kiʻekiʻe ikehu absorption, ka hopena maikaʻi o ka hopena; |
| ʻO ka mākeke huahana | Me ka hoʻomohala wikiwiki o ka hoʻokele waiwai o Kina, ke piʻi aʻe a kiʻekiʻe ka ikaika o ka corrosion a me ka ikaika o nā mea, a me ka nui o ka fluctuation o nā kumukūʻai maka, ʻoi aku ka maikaʻi o ka hoʻomohala ʻana i nā mea hoʻopakele i ka ikehu e nā mea hoʻohana, ke kila pālua. Loaʻa iā ia nā pōmaikaʻi ma luna, ʻoi aku ka nui o ka hoʻohana ʻana i nā ʻano āpau o ke ola, ākea ka manaʻo o ka mākeke. |
316/304 Duplex Stainless Steel:
ʻO ka Duplex stainless steel kahi ʻano o ke kila kila e hoʻohui i nā pono o nā mea kila austenitic a me ka ferritic. Hōʻike ka inoa "duplex" i ka microstructure pālua ʻelua o ka alloy, ʻo ia ka austenitic (ke alo-centered cubic crystal structure) a me ka ferritic (body-centered cubic crystal structure). Hāʻawi kēia hui kūʻokoʻa o nā microstructures i kahi pūʻulu o nā waiwai e hana i ka duplex stainless steel i kūpono kūpono no nā ʻano noi koi.
Huina:
Loaʻa i nā kila kuhiliʻole Duplex ka nui nui o ka chromium (mai ka 19% a hiki i ka 32%) a me ka nickel (ma kahi o 5% a hiki i ka 8%), e like me nā kila kila austenitic. Eia hou, loaʻa iā lākou ka molybdenum kiʻekiʻe aʻe (a hiki i 5%) a i kekahi manawa nā mea hoʻohui like ʻole e like me ka nitrogen a me ka manganese. 'Oko'a ka haku mele 'ana ma muli o ka pae o ke kila kuhili'ole duplex.
Nā waiwai kī:
Paʻa ʻino: Hāʻawi ʻo Duplex stainless steel i ke kūpaʻa ʻino maikaʻi loa, ʻoi aku ka maikaʻi ma nā wahi koʻikoʻi e like me nā hāʻina chloride. He mea kūpono kēia no nā noi i ka hana kemika, nā kai moana, a me nā ʻoihana ʻaila a me nā kinoea.
Ka ikaika kiʻekiʻe: Hōʻike ka Duplex stainless steel i ka ikaika kiʻekiʻe ma mua o ka austenitic a me ka ferritic stainless steel. ʻO kēia ikaika i hoʻonui ʻia e hiki ai i ka hoʻohana ʻana i nā ʻāpana ʻoi aku ka liʻiliʻi i nā ʻāpana hoʻolālā, e hāʻawi ana i ka hoʻēmi kaumaha i nā noi like ʻole.
ʻO ka paʻakikī maikaʻi a me ka Ductility: Mālama ʻo Duplex stainless steel i ka paʻakikī maikaʻi a me ka ductility a hiki i nā haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi i nā noi i mea nui ka pale ʻana i ka hopena.
ʻO ke koʻikoʻi kūʻē i ka pohā ʻana: ʻOi aku ka maikaʻi o ke kūʻē ʻana o ke kila kila ʻole Duplex i ke koʻikoʻi o ka ʻāʻī ʻana ma mua o nā kila kila austenitic, ʻoi aku ka maikaʻi ma nā wahi waiwai chloride.
Weldability: ʻOiai ʻaʻole hiki ke hoʻopaʻa maʻalahi ʻia ka duplex stainless steel e like me austenitic stainless steel, hiki i nā ʻenehana wili hou a me nā kaʻina hana kūpono ke hiki ke hoʻokō i nā welds ikaika a hilinaʻi i nā mea duplex.
Nā noi:
Ma muli o kona hui pū ʻana o nā waiwai, hoʻohana ʻia ka duplex stainless steel i nā ʻoihana like ʻole a me nā noi, me:
Ka Hana Kemika: ʻO nā lako e like me nā ipu kaomi, nā ʻōnaehana paipu, a me nā mea hoʻololi wela i nā mea kanu hoʻoponopono kemika e pōmaikaʻi mai ke kūpaʻa ʻana a me ka ikaika o ka duplex stainless steel.
ʻAila a me Gas: Hoʻohana ʻia ka Duplex stainless steel ma waho a me uka o ka ʻaila aila a me nā keʻena kinoea no nā paipu, nā valve, a me nā mea ʻē aʻe i ʻike ʻia i nā kaiapuni corrosive.
Desalination: ʻO ke kūpaʻa ʻino o ka duplex stainless steel e kūpono i nā mea kanu desalination kahi i ʻike ʻia i ka wai kai.
ʻEnekinia moana: ʻO nā mea e like me nā propellers, shafts, a me nā mea hoʻopaʻa i nā kaiapuni moana e pōmaikaʻi mai ke kūpaʻa ʻana a me ka ikaika o ka duplex stainless steel.
Nā mea hana hale: Hoʻohana ʻia ka Duplex stainless steel i nā ʻāpana hoʻolālā no ka hoʻolālā a me ke kūkulu ʻana, ʻoi aku hoʻi i nā wahi me nā mea corrosive.
I ka hopena, ʻo ka duplex stainless steel kahi mea maʻalahi e hoʻohui i nā ʻano maikaʻi loa o nā austenitic a me ka ferritic stainless steels. ʻO kāna mau waiwai kūʻokoʻa he koho maikaʻi loa ia no nā noi kahi e koi nui ai ke kūpaʻa corrosion, ka ikaika, a me ka paʻakikī. I ka holomua ʻana o ka ʻenehana, hoʻomau ka hoʻomohala ʻana i nā māka stainless steel duplex hou e hoʻonui i kāna ʻano o nā noi ma nā ʻoihana like ʻole.
