What is EN 10025 steel grade?

EN 10025 is a European standard for hot-rolled structural steel products. It specifies technical delivery conditions for general structural steels, covering a wide range of grades and thicknesses. The standard is divided into several parts, each covering different aspects of the steel grades and their respective properties.

The main parts of EN 10025 include:

EN 10025-2: This part covers the technical delivery conditions for non-alloy structural steels. It includes grades such as S235, S275, S355, etc., which are widely used in various construction and engineering applications.

EN 10025-3: This part focuses on the technical delivery conditions for normalized/normalized rolled weldable fine grain structural steels. It includes grades like S275N, S275NL, S355N, S355NL, and others.

EN 10025-4: This part covers the technical delivery conditions for thermomechanical rolled weldable fine grain structural steels. It includes grades like S275M, S275ML, S355M, S355ML, and more.

EN 10025-5: This part specifies the technical delivery conditions for structural steels with improved atmospheric corrosion resistance. It includes grades such as S355J0W, S355J2W, S355K2W, etc.

EN 10025-6: This part focuses on the technical delivery conditions for flat products of high yield strength structural steels in the quenched and tempered condition. It includes grades like S460Q, S500Q, S690Q, etc.

The specific grade designation within EN 10025 indicates the minimum yield strength, tensile strength, impact energy, and other mechanical properties required for that particular grade.

EN 10025 steel grades are widely used in various industries, including construction, bridges, infrastructure, machinery, and more, providing structural integrity and strength to a wide range of applications.
