Qhov sib txawv tseem ceeb ntawm duplex 2205 thiab 316 stainless hlau tau piav qhia hauv qab no: 1. Cov khoom sib xyaw: Duplex 2205 yog ib hom duplex stainless hlau, uas yog kev sib xyaw ntawm austenitic stainless hlau thiab ferritic stainless hlau. Nws muaj cov khoom sib xyaw li ntawm 22% chromium, 5% nickel, 3% molybdenum thiab 4.5% nitrogen. Ntawm qhov tod tes, 316 stainless hlau yog ib qho austenitic stainless hlau alloy uas muaj cov khoom sib xyaw li ntawm 16-18% chromium, 10-14% nickel, 2-3% molybdenum, thiab me me ntawm lwm yam khoom xws li carbon, manganese, thiab silicon. 2. Kev tiv thaiv xeb: Piv nrog 316 stainless hlau, duplex 2205 muaj kev tiv thaiv xeb zoo dua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nplua nuj nyob rau hauv chloride. Nws tau ua kom muaj kev tiv thaiv rau pitting, crevice corrosion thiab kev ntxhov siab corrosion cracking. Qhov no ua rau duplex hlau 2205 zoo tagnrho rau kev siv hauv marine, roj thiab roj, thiab tshuaj lom neeg kev lag luam. 316 stainless hlau kuj ua pov thawj zoo tiv thaiv xeb, tab sis tej zaum yuav tsis zoo li duplex 2205 hauv chloride ib puag ncig. 3. Lub zog: Lub zog ntawm duplex 2205 yog siab dua li ntawm 316 stainless hlau. Nws cov qauv biphasic pab txhawb rau nws cov khoom siv zoo heev, xws li siab dua tensile thiab yield zog. Qhov zoo ntawm lub zog no ua rau duplex 2205 haum rau cov ntawv thov uas xav tau lub zog siab thiab kev ntseeg siab. 4. Nqe: Duplex 2205 feem ntau kim dua li 316 stainless hlau vim yog cov khoom siv kim thiab cov txheej txheem tsim khoom nyuaj. Kev ntxiv cov ntsiab lus alloying xws li nitrogen thiab molybdenum ua rau cov nqi tsim khoom ntau ntxiv. Txawm li cas los xij, qhov sib txawv ntawm tus nqi yuav txawv raws li cov xwm txheej kev ua lag luam thiab lwm yam. Hauv kev xaus, piv rau 316 stainless hlau, duplex 2205 muaj kev tiv thaiv corrosion zoo heev, muaj zog dua thiab weldability zoo. Txawm li cas los xij, qhov kev xaiv ntawm ob qho yuav nyob ntawm cov kev xav tau daim ntawv thov tshwj xeeb thiab kev txiav txim siab nyiaj txiag. ntawm kwv yees li 22% chromium, 5% nickel, 3% molybdenum thiab 4.5% nitrogen. Ntawm qhov tod tes, 316 stainless hlau yog ib qho austenitic stainless hlau alloy uas muaj kwv yees li 16-18% chromium, 10-14% nickel, 2-3% molybdenum, thiab me me ntawm lwm yam ntsiab lus xws li carbon, manganese, thiab silicon. 2. Kev tiv thaiv corrosion: Piv nrog 316 stainless hlau, duplex 2205 muaj kev tiv thaiv corrosion zoo dua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nplua nuj nyob rau hauv chloride. Nws tau nce kev tiv thaiv rau pitting, crevice corrosion thiab kev ntxhov siab corrosion cracking. Qhov no ua rau duplex hlau 2205 zoo tagnrho rau daim ntawv thov hauv marine, roj thiab roj, thiab tshuaj lom neeg kev lag luam. 316 stainless hlau kuj ua rau pom kev tiv thaiv corrosion zoo, tab sis tej zaum yuav tsis zoo li duplex 2205 hauv chloride ib puag ncig. 3. Lub zog: Lub zog ntawm duplex 2205 siab dua li ntawm 316 stainless hlau. Nws cov qauv biphasic pab txhawb rau nws cov khoom siv zoo heev, xws li tensile siab dua thiab cov zis muaj zog. Qhov zoo ntawm lub zog no ua rau duplex 2205 haum rau cov ntawv thov uas xav tau lub zog siab thiab kev ntseeg siab. 4. Nqe: Duplex 2205 feem ntau kim dua li 316 stainless hlau vim yog cov nqi khoom siv siab thiab cov txheej txheem tsim khoom nyuaj. Kev ntxiv cov ntsiab lus alloying xws li nitrogen thiab molybdenum ua rau cov nqi tsim khoom ntau ntxiv. Txawm li cas los xij, qhov sib txawv ntawm tus nqi yuav txawv raws li cov xwm txheej kev ua lag luam thiab lwm yam. Hauv kev xaus, piv nrog 316 stainless hlau, duplex 2205 muaj kev tiv thaiv corrosion zoo heev, lub zog siab dua thiab weldability zoo. Txawm li cas los xij, kev xaiv ntawm ob qho yuav nyob ntawm cov kev xav tau daim ntawv thov tshwj xeeb thiab kev txiav txim siab nyiaj txiag.
