Hoʻohana nui ʻia ʻo Duplex 2205 stainless steel (ferritic a me austenitic) i nā noi e pono ai ke kūpaʻa maikaʻi a me ka ikaika.Ua hoʻololi ʻia ke kila kila kila S31803 ma muli o ka UNS S32205, a ua ʻae ʻia i ka makahiki 1996. Hāʻawi kēia papa i ke kūpaʻa kiʻekiʻe i ka corrosion.
Ma nā mahana ma luna o 300 ° C, e hoʻomāhuahua ka ua nā micro-constituent o kēia papa, a ma nā mahana ma lalo o -50 ° C e hoʻololi nā micro-constituents i ka ductile-to-brittle transition;no laila ʻaʻole kūpono kēia ʻano o ke kila kila no ka hoʻohana ʻana i kēia mau wela.
Na Waiwai Ki
Ke kila kila – Papa 2205 Duplex (UNS S32205)
ʻO nā waiwai i ʻōlelo ʻia ma nā papa ma lalo nei e pili ana i nā huahana i ʻōwili ʻia e like me nā papa, nā lau a me nā coils o ka ASTM A240 a i ʻole A240M.ʻAʻole like paha kēia ma nā huahana ʻē aʻe e like me nā kaola a me nā paipu.

Aia ma lalo ka papa inoa o nā māka ʻokoʻa, hiki ke koho ʻia ma kahi o 2205.
Papa 5-Hoʻohālikelike ʻano kikoʻī no ka 2205 grade stainless steel

Pale ʻino
Nā moʻolelo pili
Hōʻike ka papa 2205 stainless steel i ke kūpaʻa ʻino maikaʻi loa, ʻoi aku ka kiʻekiʻe ma mua o ka papa 316. Kūʻē ʻo ia i nā ʻano corrosion kūloko e like me intergranular, crevice and pitting.ʻO ka CPT o kēia ʻano kila kila ma kahi o 35°C.Kūleʻa kēia papa i ka chloride stress corrosion cracking (SCC) ma nā mahana o 150°C.ʻO nā kila kila ʻole o ka papa 2205 he mau pani kūpono i nā māka austenitic, ʻoi aku hoʻi i nā kaiapuni hāʻule mua a me nā kaiapuni kai.
Kū'ē wela
Hoʻopilikia ʻia ka waiwai kūʻē o ka oxidation kiʻekiʻe o ka Papa 2205 e kona embrittlement ma luna o 300°C.Hiki ke hoʻololi ʻia kēia embrittlement e kahi lāʻau annealing solution piha.Hana maikaʻi kēia papa ma nā mahana ma lalo o 300°C.
Hoʻomaʻamaʻa Wela
ʻO ka lāʻau wela kūpono loa no kēia papa ʻo ia ka lāʻau hoʻonā (annealing), ma waena o 1020 – 1100°C, a ukali ʻia e ka hoʻomaloʻo wikiwiki.Hiki ke hoʻopaʻakikī ʻia ka papa 2205 akā ʻaʻole hiki ke hoʻopaʻakikī ʻia e nā ʻano wela.
wiliwili
ʻO ka hapa nui o nā ʻano hana kuʻihao maʻamau e kūpono i kēia papa, koe wale ka wili me ka ʻole o nā metala hoʻopiha, e hopena i ka ferrite keu.AS 1554.6 pre-qualifies welding for 2205 me 2209 rods a electrodes i mea e loaʻa ai i ka metala i waiho ʻia ke ʻano duplex kaulike kūpono.
ʻO ka hoʻohui ʻana i ka nitrogen i ke kinoea pale e hōʻoia i ka hoʻohui ʻia ʻana o ka austenite kūpono i ka hale.Pono e mālama i ka hoʻokomo wela ma kahi haʻahaʻa, a pono e pale ʻia ka hoʻohana ʻana i ka wela ma mua a ma hope paha.He haʻahaʻa ka co-efficient o ka hoʻonui wela no kēia papa;no laila ʻoi aku ka liʻiliʻi o ka distortion a me nā koʻikoʻi ma mua o nā māka austenite.
Mīkini
He haʻahaʻa ka machinability o kēia papa ma muli o kona ikaika kiʻekiʻe.ʻO ka wikiwiki o ka ʻoki ʻana ma kahi o 20% haʻahaʻa ma mua o ka papa 304.
Hana ʻia
Hoʻopili pū ʻia ka hana ʻana o kēia papa e kona ikaika.Pono ke kulou a me ka hana ʻana o kēia papa me nā lako ʻoi aku ka nui.ʻOi aku ka liʻiliʻi o ka papa 2205 ma mua o nā māka austenitic;no laila, ʻaʻole hiki ke poʻo anu ma kēia papa.I mea e hoʻokō ai i nā hana poʻomanaʻo anu ma kēia papa, pono e hoʻokō ʻia ka annealing waena.
Nā noi
ʻO kekahi o nā noi maʻamau o ka duplex steel grade 2205 i helu ʻia ma lalo nei:
- ʻImi ʻaila a me ke kinoea
- Mea hana hana
- ʻO ka lawe ʻana, mālama a me ka hana kemika
- ʻO ka chloride kiʻekiʻe a me ke kai
- ʻO nā mīkini pepa, nā pahu waiʻona, nā pulp a me nā mea ʻeli pepa
