Dab tsi yog Weathering Steel

Weathering steel, uas yog, atmospheric corrosion-resistant steel, yog ib tug tsawg-alloy steel series ntawm zoo tib yam hlau thiab stainless hlau. Weathering steel yog ua los ntawm cov pa roj carbon steel nrog me me ntawm corrosion-resistant ntsiab xws li tooj liab thiab npib tsib xee. Nws muaj lub zog, toughness thiab plasticity ntawm high-zoo steel Extension, sib sau, vuam thiab txiav, abrasion, kub kub, qaug zog thiab lwm yam ntxwv; huab cua tsis kam yog 2-8 npaug ntawm cov pa roj carbon ib txwm, thiab txheej txheej yog 1.5-10 npaug ntawm cov pa roj carbon ib txwm. 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, thiab kev ua haujlwm thiab kev txuag hluav taws xob. Weathering steel feem ntau yog siv rau cov qauv steel uas raug rau cov huab cua ntev ntev, xws li kev tsheb ciav hlau, tsheb, txuas hniav, yees, photovoltaics, thiab cov phiaj xwm kev kub ceev. Nws yog siv los tsim cov khoom siv xws li ntim khoom, tsheb ciav hlau, roj derricks, seaport cov tsev, cov chaw tsim roj, thiab cov thawv ntim uas muaj hydrogen sulfide corrosive nruab nrab hauv cov khoom siv tshuaj thiab roj av.
