S355JR

 S355JR

About the named of S355JR steel,JR denotes the materials toughness by reference to Charpy_V impacting test at room temperature (20 C).In chinese steel standard GB,these is also one steel grade is the same as S355JR,it is Q345B and ST52-3 under DIN 17100.These steel grades owned similar chemical composition and mechanical property when rolling.Xinsteel would offer steel plate S355JR and S355JR N under completely EN 10025-2 steel standard.
