EN10025-2 is Standard Specification for Structural Steel, for general structural purposes.
S355J2 structural steel specification in the following:
S355 – a structural grade steel with a minimum yield strength of 355 N/mm²
EN10025 S355 steel is often used in the most demanding environments such as the offshore industry S355, S355JR,
S355J2, S355J2+N steel in plate, round bar, flat bar and blocks.
S355 steel is a low carbon steel whose specifications offer high yield strength. The average minimum yield for S355 steel is 355 N/mm² giving its name: S355.
