What is the S355N structural steel?

S355N series steel is a European standard hot-rolled structural steel product, other materials of the same series such as S355J0, S355K2, S355J2.

S355N material is alloy structural steel under EN10025-2 standard. S stands for structural steel, 355 stands for yield strength, and N stands for normalizing, which is equivalent to the national standard Q345E.
