S235JR yog qhov qis-} carbon, siab}}}}}}}}}} lub zog steel dav siv hauv kev tsim kho, engineering, thiab machinery manufacturing. Qhov "JR" (Joule ntsuam xyuas) qhia cov khoom siv lub zog muaj peev xwm ua qhov kev ntsuas cuam tshuam, cuam tshuam nws cov kev nruj thiab kav ntev.
S235JR muaj lub zog los ntawm ntau dua lossis sib npaug nrog rau ntau dua lossis sib luag ntawm 27 @ J-1e -20 degree, ua rau nws muaj kev ntseeg siab thiab muaj kev sib raug zoo.
Cov hlau no muaj kev zoo heev machinability thiab tuaj yeem ua tiav los ntawm kev txiav, khoov, tswj arc vuam), tswj lub zog siab thiab tawv me ntsis tom qab vuam.
S235JR lub kaum sab xis steel yog feem ntau siv nyob rau hauv kev ua haujlwm ntawm lub tsev, cov qauv hlau ua lub chaw tsim khoom, txuas hniav, machinery pab tau, thiab racks cia. Nrog nws cov siab tawv, kav ntev, thiab ua haujlwm zoo, S235JR tau dhau los ua cov khoom siv tsis taus thiab ntau yam hauv kev tsim kho.
