Ka nānāʻana i ka nānāʻana o Duplex Guilless Steel 2205

1. Hōʻikeʻike

ʻO ka kila kila fuplex (DSS) ua lilo i mea iʻikeʻoleʻia i nā noi e koi ai i nā hanaʻelua a me ka hana.

ʻO ka kila kila fuplex 2205 (Us s31803 / s32205), Me ka microstructure like me nā'āpana likeʻole o nā'āpana likeʻole, Hāʻawi i nā mea i hoʻonuiʻia i nā mechanical a me nā waiwai o Corrosioni.

ʻO nā loea a me nā loeaʻoihana 2205 No nā noi koʻikoʻi i ka aila & aila, Ke kālepaʻana, ʻO nā wahi kai moana, a me ka kūkuluʻana ma muli o kāna hana kaulike a me nā pono waiwai.

Hōʻike kēiaʻatikala i kaʻae, waiwai, ʻO nāʻenehana hana, noi, a me nāʻano e pili ana i ka wā e pili ana i 2205 DSS.

ʻO kā mākou hoʻonohonoho pono e nānā pono i kāna huiʻana, hana kino, Loaʻa nā pōmaikaʻi konō, me nā mea hana hoʻokūkū a me nā mea hoʻonāukiuki i ka pae.

2. Evolution o ka kila kila duplex 2205

Ka hoʻomohalaʻana o ka mea kila fuplex 2205 Hōʻike i kahi milestone koʻikoʻi i ka neʻeʻana o ka metallirgical evolution o nā mea kilokilo.

Hōʻike kēia'āpana i nā kumu kumu, kū kūʻokoʻa, a me ka hanaʻoihanaʻoihana o kēia waihona, Ke hōʻike nei i ka pehea o ka hōʻikeʻana o ka inoa inoa inoa i alakaʻi i kona hoʻolahaʻana i nā noi noi.

ʻO ka wehewehe a me ka heluʻana o nā mea kanu manuʻole

E hoʻokaʻawaleʻia nā mea hoʻokūkū Duplex i kā lākou ʻO ka microstructure dual-phise, e hoʻohālikelike ana i nāʻano like like o ferrite (a) and Austente (c).

Hāʻawi kēia hoʻonohonoho kūʻokoʻa iā lākou i kahi hana hana hybrid hana-hōʻike i ka ikaika kiʻekiʻe a me ka chordide style stick of stictic, a me ka paʻakikī a me ka weldability of Austeticic Steels.

Ua helu pinepineʻia nā pahu Duplex iʻekolu mau māhele:

• Lean Duplex Graves (E.g., 2101, me nā kelepona haʻahaʻa a me nā molybdenum),
• Nā helu Duplex maʻamau (Kahi 2205),
• ʻO nā māka Duplex Super Dulex (E.g., 2507, No nā wahi ellra-untra).

I waena o kēia mau, ʻO ka kila kila fuplex 2205-Ke -ka ma lalo iho Us s31803 a hoʻomaikaʻiʻia Us s32205-ʻO nā mea i kū mai e like me ka mea hana o ka hui, ʻO ka hana kaulike me ka hana waiwai.

Ua koiʻia me nā kūlana o ke kī nui, e like me:

• Astm A240 / A240M (papaʻi, she wallpaper, a e huki),
• I 10088-2 (General Corrisiona-resistant steel),
• ISO 15156-3 / ISH MR0175 (Nā mea hana no ka hoʻohanaʻana i ka H₂s-i loaʻa i ka aila aila).

Ka hoʻomohala honua a me ke kūkuluʻana

ʻO ka manaʻo o ka Duplex Stainless Steels i nā lā e hoʻi hou ana i ka mau makahiki 1930, me nā paka mua i hoʻopaʻaʻia ma Sweden ma Avesta (I kēia manawa).

Akā naʻe,, Loaʻaʻia nā mea nui a Duplex mai ka pōʻino maikaʻiʻole a me ka wāʻole ma muli o ke kalaiwa kiʻekiʻe aʻaʻole lawa ka mana o ka nitrogen.

ʻAʻole ia a hiki i ka 1970s a me 1980s i kēlā mau mea momona maikaʻi loa,
loa a ua hoʻopiliʻia i hoʻohuiʻia o ka nitrogen a me keʻano haʻahaʻa haʻahaʻa, uaʻaeʻia ka pukaʻana o nā helu helu kūʻai likeʻole 2205.

Ka hoʻopili kūponoʻole o ~ 0.14-0.25% nitrogen ʻaʻole i hoʻoikaika wale i ka phase austetitic akā ua lohi pū kekahi i ka hoʻokumuʻana o nā hana intmental intmental e like me Sigma (a).

'Ōlelo transition mai s31803 i S32205 ua hele mai ma hope o keʻano metallirgic optimitation i nā makahiki 1990, me ka hope hope:

• Hoʻonui i ke kaulike phase (ʻoi aku ka maikaʻi),
• Hoʻomaikaʻiʻia i ke kū'ē (Wood ≥ 35),
• ʻOi aku ka maikaʻi a me ka welltibility.

E like me ia, Duplex 2205 lilo i hana maʻamau ma keʻano he 2000s, ke hoʻololi nei i nā helu Austetitic he nui i nā wahi e kū'ē ai i nā wahi e like me ka ikaika a me ke kūʻana o ka ikaika.

ʻO ka mana o kaʻenehana a me ka hoʻonohonohoʻana

Ka hāpaiʻana o Duplex 2205 ua hoʻopuka pūʻia i ka Evolution o nā hana hana.

ʻO nāʻano hana maʻamau hou-e like me gas tungsten arc welding (Gtaw) me ka hanaʻana i nā hana wela wela-a hoʻonuiʻia e hoʻonuiʻia e mālama i ka kaulike o ka maikaʻi.

ʻO kēia Innovant ecorystem smarred i ka hoʻohuiʻana o 2205 i loko o nā mea hana kūpono, nā mea hana wela, a me nā moku reactor.

Eia hou, Ua kōkua ke kumu no ka hoʻokele honua honua i kūkulu i ka hilinaʻi o kaʻoihana.

Nā Kūlana Kūlana Asme sa-240, Dnv-gl rp f112, and 5ld ahi E hoʻopili pono i nā kulekele no ka hoʻohanaʻana o 2205 DSS, ka manaʻoʻana i kona hilinaʻi iʻikeʻia ma ke kaomiʻana i nā noi a me nā mea hōʻoia.

3. ʻO ka hui uila a me ka hoʻolālāʻana o Microstructural

ʻO ka hana maikaʻi loa o ka mea kila fuplex 2205 moe i loko o kānaʻano mīkini hoʻohālikelike me keʻano o keʻano o ka molokama a me kona mau kālā maikaʻi loa.

ʻAʻole e hoʻonui wale kēia synergy i nā mea i hoʻopaʻaʻia a me nā corrosioni e kū pono ana i ka alloy e hoʻokō pinepine i nā mea hoʻokūkū paʻakikī.

I kēia'āpana, e hana mākou i loko o ka hoʻohui hoʻohuiʻana o 2205 a me ke koʻikoʻi o kāna moekoloheʻana Microstructher, ukaliʻia e kahi loiloi hoʻohālikelike me nāʻohana kila'ē aʻe.

ʻO keʻano o keʻano o ka duplex 2205

ʻO ka kila kila fuplex 2205, papa mua i lalo o lalo Us s32205, nā hiʻohiʻona maikaʻi loa i hana ponoʻia i nā mea i hoʻolālāʻia e hoʻopaʻaʻia e hoʻopili i nā mea ferriticʻelua a me nā hana austetitic.

6. ʻO nā lāʻau a me nā cons no ka mea kila fuplex 2205

Pros of duplex stickless steelless 2205

ʻO ke kiʻekiʻe o ka ikaika ikaika

Duplex 2205 hāʻawi i kahi hoʻonui ikaika ikaika ma luna o nā helu Austenitical Austetitic.

Me nā ikaika e hāʻawi ana i nā ikaika 450 i 620 Mpa, Eʻae ia i nā meaʻenehana e hoʻolālā me nā'āpanaʻili me keʻanoʻole o keʻano kūpono.

Ua unuhi kēia hoʻomaikaʻi i nā mea kaupaona nui, ʻO ka mea koʻikoʻi no nā noi i nā papa hana ma waho, nā ipu koʻikoʻi, a me ka halihali.

ʻO ka paleʻana o ka corrossion

Kekahi o nā pono nui o 2205 ʻo ia ka mea e hoʻonui ai i ke kuʻekuʻe kūloko.

ʻO keʻano o ka huiʻana o Alloy 22% Chromium, 3-3.5% molybdelum, a ma kahi o 5-6% mau hopena-hopena i a ʻO ka heluʻana i keʻano kūlike (Wood) o 35-40.

Hana kēia iā Duplex 2205 maikaʻi loa e kū'ē i ka pitting, Kāleʻa Crenice Corrosioni, a me ke kaumaha o ke kaumaha, ʻoi aku i nā wahi waiwai e like me ka moana, Kekau, a me nā noi makemake.

Kumukūʻai kūpono ma mua o ke ola

ʻOiaiʻo ke kumukūʻai mua o Duplex 2205 hiki ke kiʻekiʻe aʻe ma mua o nā mea kilokilo carbon a iʻole nā ​​māka austetitic,

Ia ʻO ke ola lawelawe lawelawe a hoʻopau i ka mālamaʻana ʻO nā koi e hāʻawi i nā ola ola nui.

Eia hou, Ua hoʻohālikelikeʻia konaʻikepili Nickel i lalo me nā sticent stiinless austetetitic e kōkua i nā kumukūʻai waiwai, e hana ana i ka waiwai waiwai ma luna o ka lōʻihi.

Maikaʻi maikaʻi a me ka lole

I ka wā e hoʻohanaʻia ai nā hana hana kūpono a me nā hana wela wela, Duplex 2205 hiki ke maikaʻi i ka hoʻohanaʻana me ka hoʻohanaʻana i nāʻenehana e like me Tig (Gtaw) a aʻu (Kāmaʻa kikomua).

ʻO kāna hana nui-phase e hoʻonui ai i ke kīwī wela a hoʻonui i ka ikaika o ka pahu, hoʻolakoʻia i nā mea like e like me keʻano o keʻano o keʻano (<150 ° C) a me nā metala kūpono kūpono (E.g., ER2209) ua hoʻokele nuiʻia.

Keʻano o ka honua

Ma kahi o nā pono hana, Duplex 2205 uaʻikeʻia no kona mau pono kūlohelohe.

Kona ola lōʻihi, Recyclabiality (luna 90%), a hoʻemi i ka mālamaʻana i nā mea āpau i hāʻawiʻia i kahi wāwae haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa.

E like me ka hoʻonuiʻana o nāʻoihana i nā hana hana, 2205 kū i waho e like me kahi koho koho.

Ke hoʻololiʻana i ka naʻauao a me ka hoʻonuiʻana i ka wela wela

Mālama i ka pololei 50:50 kaulike o Austente a me Ferrite he mea nui paha no ka hoʻokōʻana i nā waiwai Mechanical makemake.

ʻO kēia kaulike ke nānā aku i nāʻano hana; hikiʻole i ka hopena wela a iʻole ka hopena wela hiki ke alakaʻi i ka hoʻokumuʻana i ka hoʻokumuʻana o nā pae waena o nā mea e like me ka sigma shase.

NOEHUI, Hoʻoponopono paʻa paʻa i ka wā o ka fabrication a me ka welding mea pono, e koi ana i nā lako hana kūikawā a me nā akamai.

ʻO ka lawelaweʻana i ke kiʻekiʻe kiʻekiʻe

Duplex 2205 ua kūpono loa no nā lawelawe lawelawe e pili ana i 300 ° C (572° F).

Ma waho o kēia paepae, Hiki i nā waiwai o nā mea waiwai ke hoʻoholo ma muli o nā loli,

Ke hana nei i kahi kūpono no nā noi e koi ana i ka hana kiʻekiʻe, e like me kekahi mau mana mana mana.

Ho'ēmi i ka hana hana anuanu
