S235JR yog cov qauv European uas tsis yog-alloy structural steel, sib npaug rau lub teb chaws tus qauv Q235B, uas yog cov qauv hlau uas muaj cov pa roj carbon tsawg.Nws yog siv rau vuam, bolting thiab riveting cov qauv.
Carbon structural steel yog ib hom carbon hlau.Cov ntsiab lus carbon yog li 0.05% ~ 0.70%, thiab qee qhov tuaj yeem siab txog 0.90%.Nws tuaj yeem muab faib ua cov qauv carbon zoo tib yam thiab cov khoom siv zoo carbon steel.Nws yog dav siv nyob rau hauv railway, choj, ntau yam kev tsim kho tej yaam num, tsim ntau yam hlau Cheebtsam uas dais static load, tsis tseem ceeb txhua yam qhov chaw thiab dav weldments uas tsis xav tau kev kho cua sov.
Qib ntawm S235JR steel phaj qhia
"S": European tus qauv zoo tib yam carbon structural steel;
"235": yield zog yog 235, unit: MPa;
"JR": cuam tshuam ntawm qhov kub thiab txias

Kev faib tawm saum npoo
Ordinary nto (FA)
Pickled nto yog tso cai kom muaj me ntsis thiab hauv zos tsis xws luag xws li pits, dents, khawb, thiab lwm yam. uas nws qhov tob (los yog qhov siab) tsis tshaj ib nrab ntawm lub thickness kam rau ua ntawm steel phaj, tab sis qhov tsawg kawg nkaus tso cai thickness ntawm steel phaj thiab steel sawb yuav tsum tau guaranteed.
Siab saum npoo (FB)
Pickling nto tau tso cai kom muaj qhov tsis xws luag hauv zos uas tsis cuam tshuam rau kev tsim, xws li khawb me ntsis, me ntsis indentations, me ntsis pits, me ntsis cov qhab nia thiab xim sib txawv.
Khoom siv
Nws yog tsuas yog siv rau lub tsev, choj, nkoj, tsheb qhov chaw, tsim ntau yam cuab yeej, txiav cov cuab yeej, pwm thiab ntsuas cov cuab yeej.
