S31803 Duplex Stainless Steel: Superior Corrosion Resistance ndi Mphamvu Zapamwamba pa Ntchito Zamakampani

S31803, yomwe imadziwikanso kuti Duplex 2205 kapena F60, ndi gulu lodziwika bwino lachitsulo chosapanga dzimbiri cha duplex pamsika wapadziko lonse lapansi. Kuzindikiridwa pansi pa Unified Numbering System (UNS), nkhaniyi ndi yamtengo wapatali chifukwa cha kukana kwa dzimbiri, mphamvu zamakina apamwamba, komanso kugwira ntchito mosiyanasiyana m'malo ovuta.

Kapangidwe Kake ndi Kapangidwe Kake

S31803 duplex chitsulo chosapanga dzimbiri imakhala ndi kusakaniza koyenera kwa zinthu zophatikiza zomwe zimapereka mawonekedwe ake apamwamba:

• Chromium (Cr):Pafupifupi 22% - Imakulitsa kukana kwa dzimbiri, makamaka motsutsana ndi maenje ndi dzimbiri.

• Nickel (Ni):Pafupifupi 5.0-6.0% - Imalimbitsa kulimba ndi ductility.

• Molybdenum (Mo):Pafupifupi 3.0% - Imakulitsa kukana kwa dzimbiri komwe kumapezeka, makamaka m'malo okhala ndi chloride.

• Nayitrogeni (N):Pafupifupi 0.18% - Imawonjezera mphamvu ndikuthandizira kupsinjika kwa dzimbiri.

Kapangidwe kakang'ono ka magawo awiri, kuphatikiza magawo a ferritic ndi austenitic, kumabweretsa zinthu zamakina zomwe zimakhala pafupifupi kuwirikiza kawiri zazitsulo zosapanga dzimbiri za austenitic pomwe zimasunga ductility komanso kulimba.

Katundu Wapadera ndi Ubwino

Kulimbana ndi Corrosion Resistance

S31803 imapambana pokana dzimbiri zosiyanasiyana, kuphatikiza:

• Pitting and Crevice Corrosion:Kuchuluka kwake kwa chromium ndi molybdenum kumalola kuti izichita bwino kwambiri m'malo a chloride.

• Stress Corrosion Cracking:Dongosolo la duplex limapereka kukana kokulirapo pakupsinjika, ngakhale atakumana ndi media zaukali.

Mphamvu Zapamwamba Zamakina

• Kuthamanga Kwambiri Kwambiri:Nthawi zambiri, mphamvu yamakomedwe ya S31803 imaposa 500 MPa, ndikupangitsa kuti ikhale yabwino pamapulogalamu apamwamba kwambiri.

• Kulimbitsa Kulimbitsa:Kukhazikika kwa microstructure sikungolimbitsa mphamvu komanso kumatsimikizira kulimba kodalirika komanso ductility, zomwe ndizofunikira kwambiri m'mafakitale amphamvu.

Wabwino Weldability

Ngakhale chisamaliro chapadera chimafunika pakuwotcherera kuti tipewe kuwonongeka m'dera lomwe limakhudzidwa ndi kutentha, njira zowotcherera moyenera ndi chithandizo chapambuyo pa kuwotcherera zimatha kuonetsetsa kuti mafupa amphamvu, opanda chilema. Izi zimapangitsa S31803 kukhala chisankho chothandiza pakupanga ndi kukonza ntchito

Industrial Applications

Chitsulo chosapanga dzimbiri cha S31803 chimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chophatikiza mphamvu zake komanso kukana dzimbiri. Magawo ofunikira ogwiritsira ntchito ndi awa:

• Zida Zopangira Chemical:Ndi abwino kwa ma reactor, akasinja osungira, ndi makina apaipi pomwe kukana mankhwala aukali kumafunika.

• Makampani a Mafuta ndi Gasi:Amagwiritsidwa ntchito kwambiri m'mapaipi, mavavu, ndi zopangira, makamaka pansi pazifukwa zamphamvu komanso zamtundu wa chloride.

• Ukatswiri wa Marine ndi Kupanga Zombo:Kukaniza kwake ku dzimbiri lamadzi amchere kumapangitsa kuti ikhale yoyenera kumadera akunyanja, zida zam'madzi, ndi zida zina zapamadzi.

• Zida Zopangira Mphamvu:Ogwiritsidwa ntchito m'mafakitale amagetsi ndi zida za nyukiliya komwe kukhulupirika kwadongosolo komanso kugwira ntchito kwanthawi yayitali ndikofunikira.

• Zomangamanga ndi Zomangamanga:Mapeto ake owoneka bwino komanso kulimba kwake kwapangitsa kuti agwiritsidwe ntchito m'mapangidwe amakono omanga ndi zokongoletsa

   

Kutsata Miyezo Yadziko Lonse

S31803 duplex zitsulo zosapanga dzimbiri zimagwirizana ndi mfundo zingapo zofunika zapadziko lonse lapansi komanso zamayiko, kuwonetsetsa kudalirika kwake komanso mtundu wake. Mwachitsanzo:

• ASME B16.11:Limanena ntchito yake popanga zitsulo weld ndi ulusi chitoliro zovekera.

• ASTM A240/A240M:Amapereka malangizo a mbale zachitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana.

• EN 10088-2:Tsatanetsatane wa zofunikira pazitsulo zosapanga dzimbiri ku Ulaya.

Kutsatira malamulo okhwima uku kumatsimikizira kuti S31803 ikukwaniritsa zofunikira pakugwiritsa ntchito padziko lonse lapansi.

Mapeto

Chitsulo chosapanga dzimbiri cha S31803 chimadziwika ngati chida chosunthika komanso cholimba chomwe chili choyenera kumadera omwe amafunikira mafakitale. Kuphatikizika kwake kwamphamvu kwambiri, kukana kwa dzimbiri, komanso kuwotcherera kodalirika kumapangitsa kukhala chisankho chapamwamba pamagawo onse monga kukonza mankhwala, mafuta ndi gasi, uinjiniya wam'madzi, kupanga mphamvu, ndi zomangamanga. Pamene mafakitale akupitiriza kukankhira malire a ntchito ndi kulimba, S31803 imakhalabe chinthu chokondedwa chomwe chimapereka phindu losatha ndi chitetezo.

Kuti mumve zambiri zaukadaulo komanso mayankho osinthidwa makonda, akatswiri am'makampani amalimbikitsidwa kuti ayang'ane ma datatiketi azinthu ndikulumikizana ndi ogulitsa odalirika.
