S355JR Structural Steel Plate is a high-strength low-alloy European standard structural steel.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.
BBN Steel would offer S355JR and S355JR N steel plate under completely EN 10025-2 steel standard.
