S235J0W weathering steels
hlau phajKhoom Taw Qhia
S235J0W muaj kev tiv thaiv corrosion zoo thiab nthuav dav. Vim nws cov tshuaj tshwj xeeb muaj pes tsawg leeg, nws tuaj yeem tiv taus acid corrosion thiab oxidation corrosion, ua rau nws tsis tshua muaj huab cua-resistant thiab muaj zog. Weathering steel yog dav siv, feem ntau hauv nkoj, tsev, txuas hniav, tsheb, kav dej, tshuab, thiab lwm yam.
S235J0W steel phaj yog lub tiaj tiaj steel nrog qhov sib piv loj ntawm qhov dav rau tuab, uas yog siv dav hauv kev lag luam. Cov hlau phaj yog muab faib ua nruab nrab thiab tuab steel daim hlau thiab nyias steel phaj raws li thickness. Sawb steel yog ib lub phaj nyias nrog lub dav nqaim thiab ntev ntev, thiab feem ntau yog muab rau hauv coils. Cov lus qhia tshwj xeeb ntawm cov hlau phaj yog qhia hauv thickness * dav * ntev (los yog coil) mm.
S235J0W nruab nrab thiab tuab steel daim hlau: Hlau daim hlau nrog lub thickness ntau dua 4 hli yog rau nruab nrab thiab tuab steel daim hlau. Ntawm lawv, steel phaj nrog lub thickness ntawm 4. hu ua cov phaj tuab, thiab cov tuab ntawm ntau tshaj 100.0mm yog hu ua cov phaj tuab ntxiv. Tam sim no, feem ntau nruab nrab thiab tuab steel daim hlau yog tsim los ntawm kub dov, thiab nruab nrab thiab tuab steel daim hlau muab faib ua tej yam nruab nrab thiab tuab steel daim hlau thiab high-zoo nruab nrab thiab tuab steel daim hlau.
Kev siv S235J0W weathering steel tseem ntsib cov teeb meem hauv qab no:
1. Corrosion ntawm vuam cov ntsiab lus: oxidation tus nqi ntawm vuam cov ntsiab lus yuav tsum zoo ib yam li lwm yam ntaub ntawv, uas yuav tsum tau tshwj xeeb vuam cov ntaub ntawv thiab cov txheej txheem.
2. Dej corrosion: Weathering steel tsis yog stainless hlau. Yog hais tias muaj dej nyob rau hauv concave ib feem ntawm weathering steel, qhov corrosion ntawm qhov chaw no yuav sai, yog li cov kua yuav tsum tau ua kom zoo.
3. Cov huab cua nplua nuj nyob hauv ntsev: Huab cua hlau yog qhov nkag siab ntau dua rau cov huab cua nplua nuj ntsev xws li Hawaii. Nyob rau hauv ib puag ncig zoo li no, cov yeeb yaj kiab tiv thaiv saum npoo yuav tsis tiv thaiv ntxiv oxidation sab hauv.
4. Discoloration: Cov txheej xeb nyob rau saum npoo ntawm huab cua hlau tuaj yeem ua rau saum npoo ntawm cov khoom nyob ze rusty.
