S235JR Kub Rolled Carbon Hlau Beams
S235JR Kub Rolled steel yog ib qib tshwj xeeb ntawm cov qauv hlau hauv cov qauv hauv European en {1}}. Qhov "S" sawv rau cov qauv hlau, "235" sawv rau qhov tsawg kawg nkaus lub zog hauv MPA, thiab "JR" qhia nws cov kev cuam tshuam ntawm chav tsev kub.
S235JR Cov Hlau Hlau yog dav siv nyob rau hauv cov haujlwm tsim dav dav, suav nrog kev tsim cov khoom siv thiab ntau yam khoom siv uas xav tau cov khoom siv muaj zog thiab muaj zog.
Kev Siv Tshuaj Ntau Yam Khoom ntawm S235JR Me Hlau H nqaj
Cov pa roj carbon (c): Cov ntsiab lus carbon yog kwv yees li {{0} {{- 0. 20% siab kawg.
Manganese (MN): Cov ntsiab lus manganese feem ntau ntawm {{0}}}. 30% thiab 0.60%.
Phosphorus (p) thiab Sulphorur (s): phosphorus cov ntsiab lus yog txwv rau ntau kawg ntawm {{}}}}}. 045%, thiab cov Sulfur cov ntsiab lus yog txwv rau ntau tshaj plaws ntawm 0.045%.
Silicon (Si): Feem ntau txog 0. 10% - 0. 35}. 35/00.
Cov Khoom Siv Neeg Kho Tshuab Ntawm S235JR Cov Hlau Hlau H Be Be
Paib lub zog: qhov tsawg kawg nkaus los lub zog yog 235 MPA.
Lub zog tensile: lub zog tensile feem ntau yog ntawm 360 thiab 510 MPa.
Elongation: qhov tsawg kawg nkaus elongation yuav tsum yog 25% ntawm 5.65sibs₀.
Kev Cuam Tshuam Cov Khoom Siv: Kev cuam tshuam zoo ntawm chav tsev kub.
Cov txheej txheem tsim ntawm S235jr H Beam Steel qauv
Kub Rolling: Lub billet yog thawj zaug ua kom sov rau qhov kub thiab maj mam zoo, thiab maj mam zoo li tus yam ntxwv h-zoo li tus cwj pwm los ntawm ib qho ntawm cov xaub mills.
Txias thiab ua tiav: tom qab kub dov, lub H-nqaj txias txias hauv txoj kev tswj hwm. Tus nqi cua txias cuam tshuam rau microstructure thiab cov khoom ntawm cov hlau. Tom qab, H-Beam yuav raug cov kauj ruam kev ntxiv xws li ncaj qha los ua kom muaj qhov ntev, thiab kev kho deg kom txhim kho nws cov tsos thiab kev kho mob corrosion. Cov kev kho hauv cov tshuaj saum npoo xws li cov xim pleev xim, galvanizing, lossis thov cov tshuaj tiv thaiv tiv thaiv xeb.
GNEE siv cov txheej txheem tswj hwm nruj kom ntseeg tau tias cov qauv siv tshuaj tsis zoo, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam los ntawm cov txheej txheem tsis zoo, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam los ntawm cov txheej txheem tsis zoo, thiab kev cuam tshuam los ntawm cov txheej txheem tsis zoo, thiab kev cuam tshuam los ntawm cov txheej txheem tsis zoo, thiab kev cuam tshuam los ntawm cov txheej txheem tsis zoo, thiab kev cuam tshuam ntawm cov kev ntsuas tsis zoo, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam nyuaj, thiab kev cuam tshuam los ntawm cov txheej txheem tsis zoo los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau sab hauv lossis saum npoo av.
