Qhov sib txawv tseem ceeb ntawm duplex 2205 thiab 316 stainless hlau tau piav qhia hauv qab no: 1. Cov Khoom Siv: Duplex 2205 yog ib hom duplex stainless hlau, uas yog kev sib xyaw ntawm austenitic stainless hlau thiab ferritic stainless hlau.Nws muaj qhov sib txawv tseem ceeb ntawm duplex 2205 thiab 316 stainless hlau tau piav qhia hauv qab no: 1. Cov Khoom Siv: Duplex 2205 yog ib hom duplex stainless hlau, uas yog kev sib xyaw ntawm austenitic stainless hlau thiab ferritic stainless hlau.Nws muaj kwv yees li 22% chromium, 5% nickel, 3% molybdenum thiab 4.5% nitrogen.Ntawm qhov tod tes, 316 stainless hlau yog austenitic stainless hlau alloy muaj kwv yees li 16-18% chromium, 10-14% npib tsib xee, 2-3% molybdenum, thiab lwm yam khoom me me xws li carbon, manganese, thiab silicon.2. Corrosion kuj: Piv nrog 316 stainless hlau, duplex 2205 muaj corrosion kuj zoo dua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nplua nuj nyob rau hauv chloride.Nws muaj zog tiv thaiv pitting, crevice corrosion thiab kev nyuaj siab corrosion cracking.Qhov no ua rau duplex steel 2205 zoo tagnrho rau kev siv hauv marine, roj thiab roj, thiab tshuaj lom neeg kev lag luam.316 stainless hlau kuj pom zoo corrosion kuj, tab sis tej zaum yuav tsis zoo li duplex 2205 nyob rau 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 cuab yeej 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 316 stainless hlau vim yog cov khoom siv siab thiab cov txheej txheem tsim khoom nyuaj.Qhov sib ntxiv ntawm cov ntsiab lus alloying xws li nitrogen thiab molybdenum nce tus nqi tsim khoom.Txawm li cas los xij, tus nqi sib txawv yuav txawv raws li kev ua lag luam thiab lwm yam.Nyob rau hauv cov ntsiab lus, piv nrog 316 stainless hlau, duplex 2205 muaj zoo heev corrosion kuj, siab zog thiab zoo weldability.Txawm li cas los xij, qhov kev xaiv ntawm ob yuav yog nyob ntawm qhov kev thov tshwj xeeb thiab kev txiav txim siab txog nyiaj txiag.s ntawm kwv yees li 22% chromium, 5% npib tsib xee, 3% molybdenum thiab 4.5% nitrogen.Ntawm qhov tod tes, 316 stainless hlau yog austenitic stainless hlau alloy muaj kwv yees li 16-18% chromium, 10-14% npib tsib xee, 2-3% molybdenum, thiab lwm yam khoom me me xws li carbon, manganese, thiab silicon.2.
