Duplex Stainless Simbi

2205 Stainless Simbi

Duplex Stainless steel giredhi 2205 (inozivikanwawo seUNS S31803/S32205, ASTM A240 Rudzi 2205, Inox 2205, AISI 318LN, SUS 329J3L, kana EN 1.4462) iri maviri-chikamu (ferritic 2% alloayteni)-2-2-alloayteni chromium, 2.5–3.5% molybdenum, 4.5–6.5% nickel, uye inenge 0.15% nitrogen. Yayo yakaenzana microstructure inopa yakasarudzika musanganiswa wesimba repamusoro uye yakanakisa corrosion kuramba. Semuyenzaniso, giredhi 2205 rinowanzova nekaviri simba regoho re316L simbi isina tsvina, zvichiita kuti vagadziri vashandise zvikamu zvakatetepa, zvakapfava pasina kupira kuita.

Iyo alloy inowanzo kupihwa mune mhinduro-yakagadziriswa mamiriro (paASTM A240/A240M) kuchengetedza yakanakira duplex chimiro. Giredhi 2205 rinoramba rakaoma kubva kune cryogenic tembiricha (yakatenderedza -50 ° C) kusvika kunosvika +300 ° C; mhiri kweiyi nhanho, brittle sigma chikamu chinogona kuumba mune welds. Izvi zvivakwa zvinoita duplex 2205 sarudzo yakanaka kwazvo yekuda maapplication akadai semakemikari kugadzirisa, offshore oiri & gasi, uye nharaunda dzemugungwa uko zvese zviri zviviri simba repamusoro uye chloride corrosion resistance inodiwa.

Chiyero cheSimba-kune-Kurema Kwakasiyana-siyana: Giredhi 2205 inopa simba regoho rakapetwa kaviri iro reakajairika austenitic simbi isina tsvina. Izvi zvinobvumira zvimiro (midziyo, matangi, mapaipi, nezvimwewo) kuti zvivakwe 30-50% zvakatetepa, zvakanyanya kuderedza uremu uye mutengo wezvinhu uku uchichengetedza zvakafanana kudzvanywa ratings kana mutoro wekutakura.

Yakanakisa Corrosion Resistance: Iyo yakakwira chromium, molybdenum, uye nitrogen yemukati inopa 2205 simbi isina tsvina zvirinani zvirinani general corrosion resistance pane 316L/317L. Iyo inopikisa gomba uye kukoromoka kwemarara munzvimbo dzine chloride-inobereka zvakanyanya zvakanyanya kupfuura mazana matatu-akateedzana mamakisi. Mune hutsinye midhiya kana mvura yegungwa, duplex 2205 inowanzopfuura yakajairika austenitics; super duplex alloys inogona kutsiva inodhura nickel alloys mumamiriro ezvinhu akaomarara.

Superior Stress Corrosion Cracking Resistance:Iyo duplex microstructure inopa yakasarudzika kuramba kune chloride stress corrosion cracking (SCC). Kunyangwe akaonda duplex mamakisi ari kure kupfuura 304/316 isina tsvina muSCC bvunzo. Izvi zvinoita kuti 2205 ive yakanakira nzvimbo dzakanyorova, dzesaline, kana dzine brackish (mashandisirwo emugungwa, kubvisa munyu, kutonhora kwemvura yegungwa, nezvimwewo) apo austenitic simbi dzinotsemuka nekushushikana.

High Toughness uye Kuneta Simba: Duplex 2205 inochengetedza kusimba kwakanyanya (kunyangwe pazasi-zero tembiricha) uye inopesana nekukura kweiyo cyclic kurodha zvirinani pane akaenzana austenitic alloys. Iyo inotora simba rakawanda pasi pekukanganisa kana kuzunguza, ichiita kuti ive yakasimba pasi pesimba kana mitoro yekukurumidzira. Kuomarara kwayo kwepamusoro kana kuchienzaniswa neannealed 304/316 inopawo yakagadziridzwa kupfeka kuramba mumamiriro ebrasive.

Yakaderera Thermal Kuwedzera uye Carbon-Simbi Kuenderana:Giredhi 2205 ine yakaderera coefficient yekuwedzera kwekupisa (pedyo neiyo carbon steel). Izvi zvinobatsira kana welding kana clad laminating kuti kabhoni simbi, sezvo kufanana kuwedzera mwero kuderedza kushushikana uye kukanganisa. Iyo inochengetedzawo kugadzikana kwedimensional kuchinjika tembiricha zviri nani pane 300-series alloys.

Chemical and Process Industries: Yakanakira midziyo yekumanikidza, yakakwirira-kudzvinyirira matangi ekuchengetedza, pombi, uye kupisa exchangers mumakemikari zvidyarwa, kugadzirwa kweasidhi, uye petrochemical refineries. Inobata corrosive acids, alkalis, uye zvinonyungudutsa apo 300-series isina tsvina inogona kukundikana.

Mafuta, Gasi uye Offshore: Inoshandiswa mumapaipi, risers, separators, uye zvikamu zvepuratifomu. Kuramba kwayo kune chloride stress corrosion kuparuka kunoita kuti ive yakakosha kune majekiseni emvura yegungwa pombi, mapaipi emvura yemunyu, uye nharaunda dzemugungwa mukuongorora nekugadzirwa kwemahombekombe.

Kurapa kwemvura uye Desalination: Inoshandirwa mumasisitimu ekutonhodza kwemvura yegungwa, zvirimwa zvekubvisa salination, uye kurapwa kwemvura yetsvina. Duplex 2205's pitting resistance inovimbisa hupenyu hurefu hwebasa mukusangana nemabrines kana mvura yakacheneswa.

Indasitiri yePulp & Mapepa: Inoshandiswa mu digesters, bleaching tower, uye matangi ekuchengetera makemikari. Inomira kutonhora kwakanyanya uye makemikari ane hukasha (sechlorine dioxide uye caustic liquor) anosanganikwa nawo mukupuruzira uye bleaching maitiro.

Chikafu, Chinwiwa uye Pharmaceutical Processing: Inokodzera matangi, mapaipi, uye midziyo mukugadzira chikafu, kubika, mukaka, uye zvidyarwa zvemishonga. Inopa kusimba uye kusagadzikana kwekuora pasi pehutsanana hwekuchenesa uye hutsanana zviyero.

Industrial Machina uye Marine Zvikamu: Inoshandiswa muzvikamu zvepombi nemavharuvhu, ma impellers, shafts, uye zvimiro zvemukati zvinoda simba rakawanda uye kusagadzikana kwekuora. Inoshandiswawo mukuvaka ngarava, zvimiro zvekunze kwemahombekombe, uye midziyo yekutakura yakafumurwa kune yakaoma mamiriro.

Zvimwe Zvishandiso zveInjiniya: Pese panodiwa musanganiswa wesimba repamusoro, kuomarara, uye kusaora. Mienzaniso inosanganisira zvisungo, maflange, machubhu ekupisa kupisa, uye zvikamu zvezvimiro mukugadzira magetsi, migodhi, nekugadzira zvakazara.
