S31803 Duplex Stainless Simbi: Superior Corrosion Resistance uye High Simba reMaindasitiri Zvishandiso.

S31803, inozivikanwawo seDuplex 2205 kana F60, igiredhi rinotariswa zvakanyanya reduplex simbi isina tsvina pamusika wepasi rose. Kuzivikanwa pasi peUnified Numbering System (UNS), chinyorwa ichi chakakosheswa nekusarudzika kwekuramba corrosion, simba repamusoro remuchina, uye kuita kwakasiyana-siyana munzvimbo dzakaoma.

Key Kemikari Kuumbwa uye Chimiro

S31803 duplex Stainless simbi inoratidzira musanganiswa wakaenzana wealloying zvinhu zvinounza zvimiro zvayo zvakatanhamara:

• Chromium (Cr):Zvingangoita 22% - Inosimudzira kusaita ngura, kunyanya kurwisa gomba uye kukoromoka.

• Nickel (Ni):Around 5.0-6.0% - Inovandudza kuoma uye ductility.

• Molybdenum (Mo):Zvingangoita 3.0% - Inowedzera kuramba kune corrosion yemuno, kunyanya munzvimbo dzine chloride-rich.

• Nitrogen (N):Inenge 0.18% - Inowedzera simba uye inobatsira kushushikana kwekuora kwekudzivirira.

Iyo yakasarudzika mbiri-chikamu microstructure, inosanganisa ferritic uye austenitic nhanho, inoguma mumichina zvivakwa zvinenge zvakapetwa kaviri izvo zvezvakajairwa austenitic stainless simbi uku ichichengetedza yakanakisa ductility uye kuoma.

Dzakatanhamara Properties uye Benefits

Enhanced Corrosion Resistance

S31803 inokunda mukuramba marudzi akasiyana ekuora, anosanganisira:

• Pitting uye Crevice Corrosion:Yayo yakakwira chromium uye molybdenum yemukati inoibvumira kuita zvakasarudzika munzvimbo dzechloride.

• Stress Corrosion Cracking:Iyo duplex chimiro inopa yakawedzera kuramba kupaza pasi pekunetsekana, kunyangwe kana yakafumurwa kune hukasha midhiya.

Superior Mechanical Simba

• High Tensile Simba:Kazhinji, simba rekusimba reS31803 rinopfuura 500 MPa, zvichiita kuti ive yakanakira kushandiswa kwepamusoro-soro.

• Kuwedzera Kusimba:Iyo yakadzikama microstructure haingosimbisi simba chete asi zvakare inovimbisa yakavimbika kuomarara uye ductility, izvo zvakakosha munzvimbo dzakasimba dzeindasitiri.

Yakanakisa Weldability

Nepo kutarisisa kwakakosha kuchidikanwa panguva yewelding kuti udzivise kushatiswa munzvimbo inopisa-inopisa, nzira dzakakodzera dzekushongedza uye kurapwa kwepashure-weld kunogona kuvimbisa yakasimba, isina kukanganisa majoini. Izvi zvinoita kuti S31803 ive sarudzo inoshanda kune ese ari maviri ekugadzira uye kugadzirisa basa

Industrial Applications

S31803 duplex Stainless simbi inowana kushandiswa kwakakura mumaindasitiri akasiyana siyana nekuda kwekubatana kwayo kwakaringana kwesimba uye kushora. Nzvimbo dzakakosha dzekushandisa dzinosanganisira:

• Chemical Processing Equipment:Yakanakira mareactor, matangi ekuchengetera, uye pombi masisitimu uko kupokana nemakemikari ane hukasha kunodiwa.

• Indasitiri yeOiri neGasi:Inoshandiswa zvakanyanya mumapaipi, mavharuvhu, uye fittings, kunyanya pasi pepamusoro-kudzvanywa uye yakakwirira-chloride mamiriro.

• Marine Engineering uye Shipbuilding:Kupokana kwayo nekuora kwemvura yemunyu kunoita kuti ive yakakodzera kune zvivakwa zvekumahombekombe, marine Hardware, uye mamwe maapplication emugungwa.

• Energy Production Facilities:Inoshandiswa mumagetsi emagetsi uye zvivakwa zvenyukireya uko kutendeseka kwechimiro uye kushanda kwenguva refu kwakakosha.

• Kuvaka uye Architectural Zvikamu:Kupera kwayo kunoyevedza uye kusimba kwakatungamira mukushandiswa kwayo muzvivakwa zvemazuva ano zvekuvaka uye aesthetic application

   

Kutevedza neInternational Standards

S31803 duplex Stainless simbi inoenderana nezvakakosha zvakati wandei zvepasirese uye yenyika zviyero, kuve nechokwadi chekuvimbika kwayo uye mhando. Semuyenzaniso:

• ASME B16.11:Inotsanangura kushandiswa kwayo mukugadzira socket weld uye threaded pombi fittings.

• ASTM A240/A240M:Inopa nhungamiro yesimbi isina tsvina mahwendefa anoshandiswa mune akasiyana maapplication.

• EN 10088-2:Details zvinodiwa kuti Stainless simbi zvigadzirwa muEurope.

Uku kuomerera kune dzakaomarara zviyero zvinovimbisa kuti S31803 inosangana nezvinodiwa zveakakosha maapplication pasi rese.

Mhedziso

S31803 duplex Stainless simbi inomira pachena sechinhu chinogoneka uye chakasimba chakanakira nzvimbo dzinoda maindasitiri. Kusanganiswa kwayo kwakanakisa kwesimba repamusoro, kukwirira kwecorrosion kuramba, uye yakavimbika weldability inoita kuti ive sarudzo yepamusoro muzvikamu zvakaita sekugadzira makemikari, oiri uye gasi, mainjiniya emugungwa, kugadzira simba, uye kuvaka. Sezvo maindasitiri achienderera mberi nekusundira miganho yekushanda uye kusimba, S31803 inoramba iri chinhu chakasarudzika chinopa kukosha kusingaperi uye kuchengetedzeka.

Kuti uwane mamwe akadzama ehunyanzvi hwekuita uye akagadziridzwa mhinduro, vashandi veindasitiri vanokurudzirwa kubvunza madheti ezvinyorwa uye kubata vatengesi vanovimbwa.
