EN S355J2 material is hot rolled structural steel specified in standard EN10025-2. In S355J2, S indicates structure steel, 355 means minimum yield strength of 355 N/mm² for S355J2 steel plates below 16mm thickness. And J2 symbol charpy v-notch impact tested longitudinal 27J at -20 ˚C under 150mm thickness.
What is EN S355J2 material equivalent steel grade in China? The answer is Q345D steel, which has a lot in common with EN S355J2 material.
