Which steel grade is best equivalent to structural steel S355J2+N according to DIN EN 10025 2

S355J2+N under DIN EN 10025-2 standard is a common structural steel material with excellent mechanical properties and a wide range of applications. When searching for equivalent materials, the closest ones may be ASTM A572 Grade 50 (American standard) or JIS SM490A (Japanese industrial standard). These two materials are similar in performance and usage to S355J2+N.

ASTM A572 Grade 50 is a commonly used high-strength low-alloy structural steel in the United States, with good weldability and mechanical properties, suitable for various engineering and construction projects. JIS SM490A is a universal structural steel in Japanese industrial standards, which has high yield strength and toughness and is widely used in manufacturing and construction industries.

Although these materials are in different standard systems, they are similar in performance and usage to S355J2+N and can be used as reference and alternative choices for equivalent materials. Designers and engineers can determine the most suitable material based on specific project requirements and regional standards when selecting materials to ensure the safety and stability of the structure.
