S355J2 (+N) (1.0570 (dubl)) , S355J2G3 (European old, EN ) - European (EU, EN) and wordwide Steel equivalent grades. These comparison table is only intended as an indication of the closest khown equivalent grades. The source standarts should always be checked for the specific purpose for each material, in case of doubt. ST52-3 High Strength Structure Steel S355J2G3 EN 1.0570Besides S355J2G3 grade, there are other grades in EN10025 such as S355J2G4, S355J2, S355J0 etc. For Grade S355J2G3, J2G3 means that the delivery status is normalized, the impact energy at -20 °C is 27J, and G3 is the means of characterizing the deoxidation method.
S355J2G3 Characteristic. S355J2G3 is a low carbon, high tensile strength structural steel which can be readily welded to other weldable steel. With its low carbon equivalent, it possesses good cold-forming properties. The plate is produced by fully killed steel process and supplied in
