Chifukwa chiyani Duplex Stainless Steel 2205?
1) Mphamvu zokolola zimaposa kuwirikiza kawiri kuposa chitsulo chosapanga dzimbiri cha austenitic, ndipo chimakhala ndi zofunikira popanga
Mapulasitiki okwanira.Makulidwe a khoma la akasinja osungira kapena zotengera zokakamiza zopangidwa ndi duplex zitsulo zosapanga dzimbiri ndi 30-50% zochepa kuposa zomwe zimagwiritsidwa ntchito nthawi zambiri austenite, zomwe zimapindulitsa kuchepetsa ndalama.
2) Ili ndi kukana kwambiri kupsinjika kwa dzimbiri kusweka.Ngakhale chitsulo chosapanga dzimbiri chopangidwa ndi duplex chokhala ndi aloyi chotsika kwambiri chimakhala ndi mphamvu yolimbana ndi kusweka kwa dzimbiri kuposa chitsulo chosapanga dzimbiri cha austenitic, makamaka m'malo okhala ndi ma chloride ayoni.Stress corrosion ndi vuto lodziwika bwino lomwe ndi lovuta kulithetsa pazitsulo zosapanga dzimbiri za austenitic.
3) Kukana kwa dzimbiri kwa 2205 duplex zitsulo zosapanga dzimbiri, zomwe zimagwiritsidwa ntchito kwambiri m'ma media ambiri, ndizabwino kuposa chitsulo chosapanga dzimbiri cha 316L, pomwe chitsulo chosapanga dzimbiri cha duplex chimakhala ndi kukana kwambiri kwa dzimbiri.M'ma TV ena, monga asidi acetic ndi formic acid Imatha kusinthanso chitsulo chosapanga dzimbiri cha alloy austenitic komanso ma aloyi osapanga dzimbiri.
4) Ili ndi kukana bwino kwa dzimbiri kwanuko.Poyerekeza ndi chitsulo chosapanga dzimbiri cha austenitic chokhala ndi aloyi yemweyo, kukana kwa dzimbiri komanso kutopa kukana kwa dzimbiri kuli bwino kuposa chitsulo chosapanga dzimbiri cha austenitic.
5) Coefficient of linear expansion ndi yotsika kuposa ya austenitic stainless steel , yomwe ili pafupi ndi ya carbon steel.Ndizoyenera kulumikizidwa ndi chitsulo cha kaboni ndipo zimakhala ndi tanthauzo lofunikira, monga kupanga mbale zophatikizika kapena zomangira.
6) Kaya ili pansi pa zinthu zosinthika kapena zokhazikika, ili ndi mphamvu yoyamwa kwambiri kuposa chitsulo chosapanga dzimbiri cha austenitic.Izi ndizomwe zimapangidwira kuti zipirire ngozi zadzidzidzi monga kugundana ndi kuphulika.Chitsulo chosapanga dzimbiri cha Duplex chili ndi maubwino odziwikiratu ndipo chili ndi phindu logwiritsa ntchito.
