S355J2WP ua raws li European tus qauv EN10025-5:2004. S355J0WP Wugang tsim ib hom huab cua-resistant steel phaj, uas yog atmospheric corrosion-resistant steel. Nws yog ib qho qis-alloy steel series ntawm cov hlau zoo tib yam thiab stainless hlau. Huab cua-resistant steel yog ua los ntawm cov pa roj carbon zoo tib yam nrog ib qho me me ntawm tooj liab, npib tsib xee thiab lwm yam corrosion-resistant ntsiab ntxiv. Nws muaj cov yam ntxwv ntawm cov hlau zoo xws li lub zog, plasticity, sib sau, vuam, puas, kub kub, thiab qaug zog tsis kam; Nws cov huab cua tsis kam yog 2 mus rau 8 npaug ntawm cov pa roj carbon zoo tib yam, thiab nws cov xim pleev xim yog 1.5 txog 10 npaug ntawm cov pa roj carbon zoo tib yam. Nyob rau tib lub sijhawm, nws yog xeb-tiv taus, tuaj yeem tiv taus corrosion thiab ncua lub neej ntawm cov khoom, tuaj yeem txo cov tuab thiab txo kev noj, txuag zog thiab lub zog, thiab lwm yam. Weathering steel yog siv rau cov qauv steel uas raug rau cov cua. ib lub sij hawm ntev, xws li railways, tsheb, txuas hniav, thiab ntauwd. Nws yog siv los tsim cov khoom siv xws li ntim khoom, tsheb ciav hlau, roj derricks, chaw nres nkoj cov tsev, cov chaw tsim roj thiab cov thawv ntim khoom uas muaj hydrogen sulfide corrosive media hauv cov khoom siv tshuaj lom neeg thiab roj av.
S355J0WP yog siv rau cov txuas hniav, nkoj, cov khoom siv fais fab, nqa thiab tsheb thauj mus los, tshuab tsim khoom thiab lwm yam khoom siv hluav taws xob thiab cov khoom siv welded uas ris ntau dua.
