S355J0WP Corrosion Resistant Steel Phaj
S355J0WP corten structural steel yog European tus qauv atmospheric corrosion resistant steel, uas yog ib tug weathering steel phaj. S355J0WP weathering steel welding yog cov hlau tsis tshua muaj hlau ua los ntawm kev ntxiv qee cov ntsiab lus alloying rau cov hlau zoo tib yam. Lub atmospheric corrosion kuj ntawm S355J0WP weathering steel yog 2-8 npaug ntawm cov pa roj carbon zoo tib yam. Nws muaj cov cuab yeej zoo thiab cov khoom siv vuam, thiab lub sijhawm ntev, qhov pom tseeb dua cov nyhuv corrosion.
S355J0WP corten hlau ntawv Piv nrog cov pa roj carbon zoo tib yam, cov hlau tsis zoo muaj qhov zoo dua corrosion nyob rau hauv cov huab cua. S355J0WP atmospheric steel yog cov hlau tsis tshua muaj hlau nrog cov txheej txheem xeb uas tiv thaiv huab cua corrosion thiab tuaj yeem siv los tsim cov qauv hlau xws li tsheb, txuas hniav, yees, thiab ntim khoom.
