S355J0 siab zog steel kev ua tau zoo
S355J0 siab zog steel phaj yog European tus qauv qis alloy siab lub zog steel phaj, thiab tus qauv siv yog EN10025. "S" sawv cev rau cov qauv hlau, "355" txhais tau tias nws cov txiaj ntsig muaj zog yog 355MPa, thiab "J0" yog hais txog qhov cuam tshuam lub zog ntsuas kub ntawm 0℃12.
S355J0 hsla cov qauv hlau muaj lub zog tensile thiab compressive zoo heev thiab tuaj yeem tiv taus qhov hnyav hnyav. Txawm tias nyob rau hauv qhov kub thiab txias ib puag ncig, S355J0 siab zog ntawv hlau tseem tuaj yeem tswj kev ua haujlwm ruaj khov thiab muaj kev cuam tshuam siab. Qhov tshwj xeeb kho S355J0 siab zog phaj muaj cov huab cua zoo heev thiab yoog raws qhov chaw hnyav.
Daim ntawv thov teb ntawm S355J0 qis alloy steel phaj
Kev tsim kho thaj chaw: siv rau kev tsim kho ntawm siab- cov tsev nce siab, cov chaw tsim khoom loj, gymnasiums thiab lwm yam qauv kom muaj kev nyab xeeb ntawm cov qauv.
Choj teb: dav siv nyob rau hauv kev tsim kho ntawm txoj kev loj choj, railway choj, overpasses, thiab lwm yam.
