S355Nl steel yog lub siab - lub zog, qis} {{{{2} {{2} { Cov qib hlau no tau paub txog nws cov kws kho zoo heev thiab yog ib feem ntawm European Cov Qauv Txheej Txheem Kawm 10025.
Cov yam ntxwv tseem ceeb thiab kev siv ntawm S355NL hlau muaj xws li:
High xa tawm lub zog: S355NL muaj tsawg kawg yog lub zog ntawm 355 MPa, ua kom haum rau cov ntawv thov tshwj xeeb load {{bearing} cov kabmob muaj peev xwm. Nws yog nquag siv nyob rau hauv kev tsim kho ntawm cov tsev, choj, thiab kev lag luam machinery.
Siv cov qauv txheej txheem: S355Nl feem ntau ua haujlwm hauv cov ntawv thov cov txheej txheem vim nws txoj kev ntseeg tau ua ke. Nws ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov khoom hnyav thiab muab kev ruaj khov hauv kev tsim kho cov haujlwm.
Txhim kho cov tawv tawv: Ib qho ntawm cov yam ntxwv txawv ntawm S355NL yog nws cov kev ua kom nruj, tshwj xeeb ntawm cov kub tsawg. Qhov no ua rau nws haum rau siv nyob rau hauv ib puag ncig txias lossis kev siv uas tuaj yeem ntsib cov khoom siv tsis sib haum.
Weldability: S355NL cov hlau yog paub rau nws cov txiaj ntsig zoo weldability, pab txhawb kev ua ke ntawm welded qauv thiab cov khoom siv nrog yooj yim. Welded cov pob qij txha siv S355NL tswj lawv cov qauv kev ntseeg siab thiab kev ua kom ruaj khov.
Formancion: S355NL yog tsim nyog, tso cai rau ntau yam duab xws li dabtsi yog khoov, dov, thiab kev ua kom txias. Cov cuab yeej no yog qhov tseem ceeb rau kev tsim cov duab ua ke thiab cov khoom pov thawj xav tau hauv kev tsim kho thiab tsim.
