S355J2 low alloy steel plate adopts the European standard EN10025-2, which is compiled by the technical committee of ECISS/TC10 Grading and Quality of Structural Steel. S355J2 low alloy steel plate is roughly equivalent to GB's Q345D S355J2, J2 means that the delivery state is normalized, and the impact energy at -20°C is 27J.
Chemical composition:
Carbon C: ≤0.22; Silicon Si: ≤0.55; Manganese Mn: ≤1.60; Phosphorus P: ≤0.025; Sulfur S: ≤0.025; Cu: ≤0.55;
S355J2 low alloy steel plate has good comprehensive mechanical properties, low temperature impact toughness, cold stamping, machinability, and is widely used in welded structures subjected to dynamic loads, such as bridges, vehicles, ships, pipelines, boilers, large containers, oil tanks, heavy machinery and equipment.
