Khoom Description
Weathering steel, uas yog, atmospheric corrosion-resistant steel, yog qis- alloy steel series ntawm cov hlau zoo tib yam thiab stainless hlau. Weathering steel yog ua los ntawm cov pa roj carbon zoo tib yam nrog ib qho me me ntawm corrosion-cov khoom tiv taus xws li tooj liab thiab npib tsib xee. Extension, sib sau, vuam thiab txiav, abrasion, kub kub, qaug zog thiab lwm yam ntxwv; Nyob rau tib lub sijhawm, nws muaj cov yam ntxwv ntawm xeb tsis kam, corrosion kuj thiab lub neej ntev ntawm cov khoom, thinning thiab noj txo, txuag zog thiab txuag hluav taws xob. Weathering steel feem ntau yog siv rau cov qauv hlau uas raug rau cov huab cua ntev ntev, xws li kev tsheb ciav hlau, tsheb, txuas hniav, yees, photovoltaics, thiab siab - cov haujlwm ceev. Nws yog siv los tsim cov khoom siv xws li ntim khoom, tsheb ciav hlau, roj derricks, seaport vaj tse, roj ntau lawm platforms thiab ntim khoom uas muaj hydrogen sulfide corrosive nruab nrab hauv tshuaj thiab roj av.
Hais txog qis- alloy structural steel nrog txheej tiv thaiv xeb uas tiv taus huab cua corrosion thiab tuaj yeem siv los tsim cov qauv hlau xws li tsheb, txuas hniav, yees, thiab ntim khoom. Piv nrog rau cov pa roj carbon zoo tib yam, cov huab cua steel muaj qhov zoo dua corrosion nyob rau hauv cov huab cua. Piv nrog rau cov hlau tsis muaj steel, cov hlau tsis muaj zog tsuas muaj me me ntawm cov hlau alloying, xws li phosphorus, tooj liab, chromium, npib tsib xee, molybdenum, niobium, vanadium, titanium, thiab lwm yam, tag nrho cov ntsiab lus ntawm alloying tsuas yog ob peb feem pua, tsis zoo li stainless hlau, uas ncav cuag 100%. Kaum ntawm kaum, yog li tus nqi kuj qis.
