According to the requirements of SEW 088/EN 10113/2-1993, the chemical composition of the provided fine grain structure steel must be checked by the manufacturer and indicated on the product test certificate.

Mechanical properties

The mechanical properties of fine grained structural steel according to SEW 088/EN 10113/2-1993 must also be checked by the manufacturer and indicated on the provided product test certificate. Under normal delivery conditions, this product must have a tensile strength of at least 370 N/mm2. Furthermore, it must have a yield point of at least 270 N/mm2, and the elongation must be at least 22%.

Weldability

The fine grained structural steel according to SEW 088/EN 10113/2-1993 is suitable for welding and has good weldability. Furthermore, it can be used in a variety of pressure resistant welding parts, such as pressure tanks and other pressure resistant parts.

Testing

When purchasing a product with fine grained structural steel according to SEW 088/EN 10113/2-1993, it is important to note that the manufacturer must check both the chemical composition and the mechanical properties of the steel. Furthermore, the manufacturer must provide a product test certificate with all relevant information. This product test certificate is crucial in ensuring that the steel product meets the necessary requirements of the SEW 088/EN 10113/2-1993 standard.

Conclusion

SEW 088/EN 10113/2-1993 is a standard for hot-rolled products with fine grained structural steel. In order to ensure that the material meets the necessary requirements, the manufacturer must check the chemical composition and mechanical properties as stated in the standard. Furthermore, the manufacturer must provide a product test certificate with all relevant information. As long as these requirements are met, the fine grained structural steel according to SEW 088/EN 10113/2-1993 is suitable for welding and has good weldability.

EN 10113/2 – 1993 Hot-Rolled Products of Fine-Grained Structural Steel Weldable – Chemical Composition and Mechanical Properties

EN 10113/2 – 1993 is a European standard that specifies the chemical composition and the mechanical properties of hot-rolled products of fine-grained structural steel weldable. The products specified in this standard include flat and long products such as: heavy plates, wide flats, hot-rolled strip, flat bars, and universal beams or columns.

This standard specifies the minimum values of the ultimate tensile strength and yield strength at room temperature as well as the value of the minimum yield point. It also specifies the values for the reduction of area, total elongation and the percent total elongation in 2 different directions. Furthermore, this standard contains information about the chemical composition of the specified steel, such as minimum and maximum carbon content, silicon and manganese content. It also specifies the maximum content for certain specified elements like phosphorus, sulfur and certain trace element, such as lead and bismuth.

EN 10113/2 – 1993 has the potential to improve the accuracy of mechanical properties measurements and increase the reliability of welded components. The chemical composition specified by this standard ensures that the steel will have an optimum combination of strength and ductility, while still having good weldability characteristics. In addition, it allows production facilities to use less energy in their production processes since the steel conforms to these mechanical properties in a more consistent way. This standard can thus help in reducing production costs and improving the quality of steel welded products.
