EN10113 S355N is european standard hot rolled steel products. Other materials with EN10113 S355N steel is S355JO steel, S355K2 steel, S355J2 steel, etc. S355N is alloy structural steel, 355 in S355N steel refers to the yield strength and N refers to normalization. The grade S355N is similar with Chinese standard Q345E. S355N steel plate is high strength plate. EN10113 S355N steel plate has high strength, especially in normalizing or normalized and tempered condition, S355N steel plate has higher comprehensive strength.
