S355 JRyog tus cwj pwm los ntawm nws qhov zoo weldability, machinability, thiab siab zog, ua rau nws yog ib qho kev xaiv nrov rau ntau yam kev siv cov qauv. Cov ntsiab lus tseem ceeb hauv S355JR suav nrog carbon (C), manganese (Mn), thiab silicon (Si), uas txhim kho nws lub zog thiab ductility. Cov ntsiab lus carbon raug txwv rau qhov siab tshaj plaws ntawm 0.20%, thaum cov ntsiab lus manganese nyob ntawm 1.0% txog 1.6%. Qhov kev sib xyaw no tso cai rau S355JR kom ua tiav qhov tsawg kawg nkaus lub zog ntawm 355 MPa, yog li lub npe "S355."

FAQ
S355JR sib npaug li cas?
S355JR cov qib sib npaug muaj cov tshuaj lom neeg zoo heev thiab cov khoom siv kho tshuab rau cov hlau S355JR. Ob lub S355JR sib npaug qib Q345B, A572 Gr 50, ST52-3, SM490B thiab S355JR steel yog cov khoom tseem ceeb ntawm BBN steel.
Cov yam ntxwv steel qib S355JR yog dab tsi?
S355JR steel muaj lub zog siab - rau - qhov hnyav piv, ua rau nws tsim nyog rau kev siv hauv kev thauj khoom- cov kabmob xws li txuas hniav, cov tsev, thiab cov qauv sab nrauv. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 355 N / mm², ua rau nws yog ib qho ntawm cov qib steel muaj zog tshaj plaws.
