Aia nā ʻokoʻa nui ma waena o ka duplex stainless steel wire mesh 2205 a me 2207 ma nā ʻano he nui. ʻO kēia ka hōʻuluʻulu kikoʻī a me ka hōʻuluʻulu o kā lākou ʻokoʻa:
ʻO ka hoʻohui kemika a me ka maʻiʻo element:
2205 duplex kila kila: ka nui o 21% chromium, 2.5% molybdenum a me 4.5% nickel-nitrogen alloy. Eia kekahi, aia kekahi nui o ka nitrogen (0.14 ~ 0.20%), a me nā mea liʻiliʻi e like me carbon, manganese, silicon, phosphorus a me ka sulfur.
2207 Duplex Stainless Steel (ʻike pū ʻia ʻo F53): Loaʻa pū kekahi i ka 21% chromium, akā ʻoi aku ka kiʻekiʻe o ka molybdenum a me ka nickel ma mua o 2205. Hiki ke ʻano liʻiliʻi ka ʻike kikoʻī ma muli o nā kūlana like ʻole a i ʻole nā ​​mea hana, akā ma ka maʻamau, ʻoi aku ka kiʻekiʻe o ka molybdenum a ʻoi aku ka kiʻekiʻe o ka nickel content.
Nā hiʻohiʻona hana:
2205 kila kuhiliʻole pālua:
Loaʻa ka ikaika kiʻekiʻe a me ka paʻakikī hopena maikaʻi.
Loaʻa iā ia ke kūpaʻa holoʻokoʻa a kūloko i ka corrosion stress.
Ma muli o ke kiʻekiʻe o ka chromium, molybdenum a me ka naikokene i loko o kona haku mele, he kiʻekiʻe ka anti-pitting corrosion like (PREN waiwai 33-34). Ma kahi kokoke i nā mea hoʻolaha kino a pau, ʻoi aku ka maikaʻi o kona pale ʻana i ka corrosion pitting a me ke kū ʻana o ka corrosion ma mua o 316L A i ʻole 317L austenitic stainless steel.
2207 kila kuhiliʻole pālua:
ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion a me ke kūpaʻa ʻana, ʻoi aku ka maikaʻi i ka media corrosive e like me nā waikawa ikaika, alkalis a me nā ion chloride.
He ʻoi aku ka ikaika a me ka paʻakikī a ʻoi aku ka lōʻihi ma mua o ke kila kila maʻamau.
Loaʻa iā ia ka plasticity maikaʻi a me ka processability, a me ka paʻakikī maikaʻi loa a me ke kūpaʻa luhi.
Nā wahi noi:
2205 duplex kila kila: hoʻohana nui ʻia i ka ʻoihana kemika, ka ʻaila a me ka ʻoihana kinoea, ka ʻenehana moana, ka ʻoihana kūkulu hale, ka ʻoihana aerospace a me nā ʻano ʻē aʻe. ʻO kona kūpaʻa maikaʻi ʻana i ka corrosion he koho maikaʻi loa ia no ka hana ʻana i nā moku, nā paepae waho a me nā mea hana ʻē aʻe.
2207 kila kuhiliʻole pālua: kūpono hoʻi no nā wahi ʻino loa, ʻoi aku hoʻi i nā wahi ʻino e like me ka ʻenekinia moana a me ka ʻoihana kemika. Ma muli o kāna mau hiʻohiʻona hana kūʻokoʻa, hoʻohana nui ʻia ia i nā māla e like me ka ʻaila a me ka hoʻoheheʻe kinoea.
Hana ʻia a me ke kumukūʻai:
2205 duplex kuhiliʻole kila i maikai weldability. ʻAʻole ia e koi i ka preheating i ka wā welding a i ʻole ka mālama wela ma hope o ka hoʻopili ʻana, e hoʻomaʻamaʻa i ke kaʻina hana kuʻi.
ʻO ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o ka hana kuʻi ʻana o 2207 duplex stainless steel a koi i nā kaʻina hana wili kūikawā. Eia kekahi, ma muli o kāna hana maikaʻi loa, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o 2207 duplex stainless steel a he kiʻekiʻe ke kumukūʻai hana.
