EN 10025-5 is an international steel standard established by the European Committee for Iron and Steel Standardization (ECISS) in 2004. It is a harmonized document that provides technical specifications for the design and procurement of steel materials. Its purpose is to ensure uniform and efficient engineering throughout Europe, thereby increasing the competitiveness of steel users and suppliers. The document is regularly updated and includes five different classes of steel—namely S235, S355, S420, S450 and S500.

The corrosion resistance of EN 10025-5 1.8961 steel is due to its special alloying elements, which are resistant to the corrosive effects of water and other elements. This makes the material suitable for use in marine environments and other atmospheres where it may be exposed to moisture.

The EN 10025-5 S355K2W is a European technical specification that applies to hot-rolled products made from structural steels in all shapes and sizes. It also provides information on the weldability of the steel, physical and chemical properties and mechanical characteristics. The specification also includes a range of additional quality and performance requirements. It applies to both weldable and non-weldable structural steels and covers steel grades corresponding to all European standards.

EN 10025-5 1.8967 steel is known for its excellent thermal properties, which make it ideal for use in external applications exposed to high temperatures. This steel is heat resistant and can resist temperatures of up to 590°C without suffering any significant loss of properties or degradation. Furthermore, this steel grade has a high melting point of 1370°C, which makes it suitable for use in temperatures up to 800°C.

Impact strength measures the steel's resistance to impacts. The impact strength of EN 10025-5 1.8945 steel is rated between 20 and 40 J/cm2.

When considering the mechanical properties, it is important to note that the steel grade itself is not a property; it is a description of the material's performance characteristics. The mechanical properties of EN 10025-5 1.8959 steel include yield strength, tensile strength, elongation, ductility, hardness, and impact strength.

There are several types of EN 10025-5 steel, including: S355J0WP, S355J2WP, S355J2W, S355K2W, S355J2G2W, and S355K2G2W. Each type contains different levels of carbon, but all are hardened using a heat-treatment process known as quenching.
