2205 Duplex Stainless hlau yog tus nqi kho tau rau ntau cov ntawv thov uas 300 series stainless hlau muaj kev ntxhov siab corrosion. Kev ntxhov siab corrosion tawg tshwm sim thaum stainless cov hlau yog raug rau tensile muaj kev ntxhov siab, thaum sib cuag nrog cov kev daws muaj chlorides. Nce kub kuj nce ntxiv qhov kev pom zoo ntawm cov hlau tsis muaj zog los ntxhov siab corrosion.

Piv nrog ferritic stainless hlau thiab Austenitic Stainless hlau, Duplex cov yeeb nkab muaj kev ua haujlwm vuam. Nws tsis yog tus dej kub uas cuam tshuam rau thaj tsam ntawm cov hlau ferritic, vim yog cov roj av uas tsis tshua muaj ntau, nws yog qhov rhiab ntau rau vuam kub tawg.

Txawm hais tias cov hom no tau zoo rau ntau cov ntawv thov, muaj qee qhov kev siv txuj ci tseem ceeb hauv ob hom.

Duplex 2205 Stainless cov hlau yog hu ua "duplex" vim tias lawv muaj ob-theem microstructure muaj cov ferritic thiab ustenitic stainless hlau nplej. Thaum Duplex stainless hlau yaj, nws soliorifies los ntawm cov kua theem rau ib tug qauv ferritic siab. Raws li cov khoom txias rau chav sov, txog ib nrab ntawm cov ferrite nplej hloov mus rau hauv cov nplej ("Islands tuaj"). Qhov tshwm sim yog microstructure ntawm kwv yees li 50% austenite thiab 50% ferrite.
