Cov khoom lag luam
Kub - Rolled lub kaum ntse ntse steel yog cov qauv siv sib xyaw ua ke, cov tshuab sib txuas, tshuab, thiab loj} kev ntsuas kev tsim cov qauv loj.
Nws tuaj yeem tsim ntau hom load - bearing} Cov kabmob sib txuas thiab tseem ua cov khoom sib koom ua ke, muab cov kev siv siab ntau thiab ntau cov kev siv.
Cov Nta Tseem Ceeb
Kub -} rolled txheej txheem:Lub kaum ntse ntse yog tsim los ntawm high - kub kub rolling, kom muaj kev ntxhov siab qis, thiab kev ruaj khov.
Ntau qhov ntau thiab tsawg:Cov ceg ntev ntev li ntawm 25-200 mm, thickness ntawm 3-20 mm, thiab ntev tuaj yeem kho tau raws li cov neeg siv khoom.
Cov Khoom Siv Neeg Kho Tshuab(Piv txwv rau Q235B kub - rolled lub kaum ntse ntse steel):
Paib lub zog:Ntau dua los yog sib npaug rau 235 MPa
Lub zog tensile:375-500 mpa
Elongation:Ntau dua los yog sib npaug rau 20%
Peev Xwm Txuas:Yuav tuaj yeem sib sau nrog bolts, vuam, lossis lwm txoj hauv kev, ua rau nws yooj yim rau daim ntawv thav duab, txhawb nqa, lossis cov cim nkhaus.
