Cov khoom siv tshuaj ntawm S355N siab lub zog steel
S355N siab zog phaj ua raws li European tus qauv EN 10025-3 thiab belongs rau qeb ntawm cov hlau tsis tshua muaj siab zog steel.
S355N siab tensile steel phaj tseem tuaj yeem tswj cov kev cuam tshuam siab nyob rau hauv qhov kub thiab txias, thiab tseem tuaj yeem tswj cov yas zoo thiab tawv ntawm qhov kub thiab txias, thiab tsis yooj yim rau tawg thiab deform.
S355N siab zog alloy steel muaj kev ua haujlwm zoo thiab tuaj yeem ua tiav los ntawm kev txiav, vuam, khoov thiab folding.
S355N siab zog uas tsis muaj alloy muaj qhov zoo ntawm lub zog siab, zoo toughness thiab kev ua tau zoo, thiab yog dav siv nyob rau hauv ntau lub teb, xws li: kev tsim cov nkoj loj; choj kev tsim kho, xws li kev loj choj, railway choj, thiab lwm yam .; cov khoom siv fais fab, nruab nrab thiab siab siab boilers thiab cov hlab ntsha siab thiab lwm yam khoom siv.
