2205 Duplex Stainless HlauPuas muaj cim rau hauv nws cov qauv ntau theem-tsim ntawm Austenite thiab Ferrite nyob rau hauv ze li 50:50 piv. Hauv kev sib piv, 304 stainless hlau feem ntau yog ib-theem Austenitic qauv, muaj 18% chromium, thiab tsis muaj Molybdenum lossis nitrogen. Qhov sib txawv no ncaj qha ua rau sib txawv ntawm cov khoom siv tshuab thiab corrosion tsis kam ntawm ob.

Stainless hlau 2205 thiab 304 stainless hlau yeeb nkab chloride ib puag ncig
ss2205 has an overwhelming advantage in chloride-containing media, with its pitting resistance equivalent (PREN=35.4) far exceeding that of 304 (PREN=18.4). In a 40% CaCl₂ solution tested at 100°C, 2205 exhibited stress corrosion cracking resistance of >1,000 teev, thaum 304 ua tsis tiav hauv tsuas yog 47 teev. Nyob rau hauv cov dej hiav txwv ib puag ncig, 304 yog txaus rau pitting thiab crevice corrosion, thaum 2205 ua pov thawj ntev lub sij hawm ruaj khov.
SS2205 thiab SS304 acidic media
Kev ntsuam xyuas nyob rau hauv 20% kev daws teeb meem ntawm 60℃tau qhia tias tus qauv corrosion ntawm 2205 tsuas yog 0.021 G / (NUCKH H), thaum muaj hnub nyoog 307. G / (Mev H). Qhov no ua rau 2205 txoj kev xaiv zoo tshaj plaws rau kev siv tshuaj lom xws li acetic acid thiab formic acid.
S32205 thiab S30400 Thaj Chaw Corrosion
2205 Outperforms 304 nyob rau hauv cov lus cog tseg ntawm kev tiv thaiv mus rau intergranular corrosion, hnav corrosion, thiab qaug zog corrosion. Tshwj xeeb tshaj yog nyob rau hauv sulphur-muaj roj thiab roj av (qhov twg h₂s / corrosion tus nqi yog qhov qis dua li cov hlau roj carbon.
