S255 S275 Channel Steel
S255 yog ib qho qis- alloy siab- lub zog cov qauv hlau uas ua tau raws li cov cai ntawm EN 10025-2. Nws yog ib qho uas tsis yog - alloy kub dov cov qauv hlau hauv European qauv. Lub npe S255 qhia tias nws qhov tsawg kawg nkaus tawm lub zog yog 25 MPa. Cov khoom no yog cov hlau uas zoo heev weldability, processability thiab corrosion kuj.
S275 yog cov pa roj carbon tsawg feem ntau siv hauv kev tsim cov khoom siv hlau ntau. Cov pa roj carbon tsawg yog cais los ntawm nws qhov loj feem hauv qab 0.3%. S275 steel muaj qhov siab tshaj plaws carbon cov ntsiab lus ntawm 0.25% thiab yooj yim rau txheej txheem, vuam thiab daim ntawv. Nws yog ib qho siv tau zoo tag nrho - lub hom phiaj steel. Nyob rau tib lub sijhawm, cov pa roj carbon tsawg kuj tseem ua lub luag haujlwm hauv inhibiting kev kho cua sov ntawm S275 steel.

S255 Channel steel yog siv rau ntau yam kev siv. Muaj peb hom kev ua tiav kom haum rau cov xwm txheej sib txawv. Cov xim dub lossis tsis yog-tiav tsis yog siv ntau vim cov hlau tuaj yeem ua xeb yam tsis muaj txheej tiv thaiv. Kub-dip galvanizing thiab priming yog ib qho kev kho mob. Galvanizing tiv thaiv corrosion los ntawm ib puag ncig thiab huab cua, thaum priming muaj txiaj ntsig zoo dua. Koj tuaj yeem xaiv ib qho ntawm lawv raws li koj lub hom phiaj.
