Nta ntawm S355J0W Weather Resistant Steel Phaj
S355J0W weathering steel yog ib hom weathering hlau, tseem hu ua atmospheric corrosion-resistant steel, yog ib tug tsawg alloy steel series ntawm zoo tib yam hlau thiab stainless hlau.Tus qauv ntawm S355J0Wcorten steel khoom yog EN10025-5:2004.
Nyob rau hauv S355J0W corten weathering steel qib sawv cev, "S" sawv cev rau cov qauv hlau, "355" sawv cev rau qhov tsawg kawg nkaus yield zog ntawm 355MPa thaum lub thickness tsawg dua los yog sib npaug rau 16 hli, "J" sawv cev rau qhov zoo identifier. ntawm qhov cuam tshuam kev ua haujlwm tus nqi, "0" sawv cev rau 0 degree cuam tshuam kev xeem, thiab "W" sawv cev rau atmospheric corrosion kuj ntawm cov hlau.
Cov yam ntxwv ntawm S355J0W corten steel
Zoo heev atmospheric corrosion kuj: S355J0W corten cov ntaub ntawv ntxiv ib qho me me ntawm tooj liab, npib tsib xee thiab lwm yam corrosion-resistant ntsiab nyob rau hauv lub hauv paus ntawm cov hlau zoo tib yam, uas muaj peev xwm tsim ib tug tuab tiv thaiv zaj duab xis nyob rau saum npoo ntawm steel phaj, zoo tiv thaiv corrosive yam xws li ya raws, oxygen thiab cov pa phem hauv qhov chaw.
Cov khoom siv zoo: S355J0W corten steel ntawv hlau zoo steel lub zog, yas txuas ntxiv, sib sau, vuam thiab txiav, hnav tsis kam, kub tsis kam thiab qaug zog thiab lwm yam ntxwv. Lub zog tawm los yog siab dua 355MPa, lub zog tensile nyob nruab nrab ntawm 410-630MPa, thiab elongation tom qab so yuav tsum ntau tshaj lossis sib npaug li 20%. Cov khoom no ua rau S355J0W corten nplooj ntawv kom ua tau zoo hauv ntau yam kev siv engineering.
Cov khoom siv vuam zoo heev: S355J0W corten steel phaj muaj cov khoom siv vuam zoo thiab tuaj yeem koom nrog ntau txoj kev vuam xws li arc vuam, roj vuam, vuam vuam, thiab lwm yam. Qhov no ua rau S355J0W corten steel phaj xaiv zoo rau ntau yam kev siv. Qhov no ua rau S355J0W corten steel ntawv dav siv hauv kev sib txuas ntawm vuam.
Kev cuam tshuam zoo toughness: thaum qhov cuam tshuam qhov kub ntawm S355J0W weathering steel ntawv yog 0 degrees, qhov cuam tshuam kev ua haujlwm yuav tsum siab dua lossis sib npaug ntawm 31J, qhia qhov cuam tshuam zoo. Qhov no qhia tau hais tias S355J0W corten daim ntawv tuaj yeem tiv taus qhov cuam tshuam loj los xyuas kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov qauv.
Kev tiv thaiv xeb, thinning thiab txo qis, kev txuag hluav taws xob thiab txuag hluav taws xob: S355J0W weathering steel ntawv muaj cov yam ntxwv ntawm kev tiv thaiv xeb, uas tuaj yeem txo qhov corrosion thiab poob ntawm cov khoom, yog li ua rau nws lub neej ua haujlwm ntev. Nyob rau tib lub sijhawm, vim tias S355J0W weathering steel ntawv muaj cov cuab yeej zoo thiab huab cua tsis kam, nws tuaj yeem txo kev siv hlau, txo tus nqi ntawm qhov project thiab ua tiav cov txiaj ntsig ntawm kev txuag hluav taws xob.
