S355j2 steel plate: material properties, application
S355J2 steel is a carbon manganese,high yield non alloy steel. It is called S355 because of the average minimum yield for this material is 355 Mpa.As a structural steel,it has excellent strength and weldability.It can be readily welded to other weldable steel. For its low carbon equivalent, it possesses good cold-forming properties. S355J2 is generally supplied in a normalized condition.
The table below show the mechanical properties of grade S355J2
