EN10025-5 S355J0W Corten Steel Phaj
S355J0W yog European tus qauv atmospheric corrosion resistant steel, belongs rau cov huab cua steel phaj, yog nyob rau hauv cov hlau zoo tib yam los ntawm kev ntxiv ib co ntawm cov alloying ntsiab ua los ntawm ib tug tsawg alloy hlau. Huab cua steel atmospheric corrosion tsis kam rau cov pa roj carbon zoo tib yam 2-8 zaug, nrog cov khoom siv zoo, vuam cov khoom, thiab lub sijhawm ntev, qhov pom tseeb dua corrosion kuj.

Lub hauv paus ntsiab lus ntawm S355JOW weathering steel
Ntxiv ib qho nyiaj ntawm cov hlau alloying hauv cov hlau, xws li P, Cu, Cr, Ni, Mo, txhawm rau txhawm rau tiv thaiv huab cua corrosion, nyob rau hauv kev cuam tshuam ntawm huab cua, nyob rau hauv lub hauv paus hlau nyob rau hauv lub cim ntawm ib tug tsis siv neeg tiv thaiv oxides, thiaj li hais tias cov nto ntawm cov hlau los tsim ib tug ntom thiab muaj zog adhesion rau cov zaj duab xis tiv thaiv, impede kev sib kis ntawm corrosion thiab kev loj hlob ntawm lub substrate tus nqi nyob rau hauv lub substrate. nws corrosion.
Nyob rau hauv cov txheej xeb thiab cov substrate ntawm qhov tsim ntawm li 50μm ~ 100μm tuab amorphous spinel- hom oxide txheej ntom thiab zoo adhesion nrog lub hauv paus hlau, vim lub hav zoov ntawm no txheej ntawm ntom oxide zaj duab xis, tiv thaiv cov atmospheric oxygen thiab dej rau cov hlau substrate improving cov ntaub ntawv sib sib zog nqus hlau, slowing cov ntaub ntawv. atmospheric corrosion kuj ntawm steel cov ntaub ntawv.
Weathering steel tuaj yeem siv thinning, siv los ua kom yooj yim rau txheej txheej, thiab ua rau cov txheej txheem ntawm kev tiv thaiv corrosion lub neej txuas ntxiv, kev txuag kev ua haujlwm thiab kev txo qis, kev kho dua tshiab ntawm cov hlau, tab sis kuj tseem niaj hnub metallurgy tuaj yeem ua ke rau hauv cov txheej txheem tshiab, cov cuab yeej tshiab, thev naus laus zis tshiab thiab ua rau nws txoj kev loj hlob thiab kev tsim kho tshiab ntawm cov hlau.
