1.4362 Duplex Stainless Hlau
1.4362 yog cov pa roj carbon tsawg, siab alloy stainless hlau, vim nws cov ntsiab lus tsawg dua 4 feem pua nickel cov ntsiab lus, cov hlau muaj cov qauv ferrite-austenite, thiaj li hu ua duplex stainless hlau.
Zuag qhia tag nrho, duplex stainless hlau muaj qhov sib npaug zoo ntawm cov ntsiab lus alloying, muaj cov ntsiab lus ferritic xws li chromium thiab molybdenum, thiab austenitic yam ntawm nickel thiab manganese. 1.4362 duplex stainless hlau phaj tuaj yeem siv los hloov 316L thiab 2205.
Vim yog cov qauv micro-element ntawm duplex, 1.4362 muaj cov khoom siv zoo heev thiab elongation zoo, hauv qee qhov chaw ntawm ASTM cov qauv, vim tias cov qauv ntev ntawm qhov ntsuas tensile zog feem ntau yog 50 hli, ntau dua li 80 hli.
Nyob rau hauv corrosion kuj ntawm stainless hlau ntsiab, chromium thiab molybdenum feem ntau ua lub luag haujlwm tseem ceeb, npib tsib xee tsis ua lub luag haujlwm tseem ceeb. Kev ua haujlwm ntawm npib tsib xee feem ntau yog ua kom muaj kev sib xyaw ntawm manganese thiab tooj liab ntawm chav tsev kub kom tsim cov pob zeb austenitic, yog li nickel plays lub luag haujlwm tseem ceeb hauv cov hlau tsim dua li kev tiv thaiv corrosion. Txij li thaum 1.4362 stainless hlau CR cov ntsiab lus siab dua 316L thiab tsis muaj molybdenum, nws cov corrosion kuj yog piv rau 316L. Tab sis siab dua 304 corrosion kuj.
