Steel Plates According to EN 10025-2

EN 10025 : 2004 is the new six-part European standard for hot-rolled structural steel. The information here covers the steels in part 2 of that standard, which are grades manufactured by Corus Strip Products UK.

The new standard designates grades differently from the previous standards for these steels. This leaflet shows the grades and their mechanical properties from the new standard together with the nearest equivalent grades from former standards. It also contains advice about specifying these steels when ordering.Details of the dimensional range are available from Corus.

The most commonly used structural steels having minimum yield strength min. 235 MPa and guaranteed weldability that can be used for low demanding steel structures for bridges, halls, parts of railway and motor vehicles, etc.

1) CEV= ; valid for thickness up to 30 mm, for higher thickness refer to the standard

2) Valid for thickness up to 16 mm, for higher thickness refer to the standard

3) Higher thickness on agreement

4) Under standard

5)This grade has been removed from the standard because it does not offer a guaranteed minimum impact performance, which is required

by the EU Construction Products Directive (CPD 89/106/EC). The lowest grade offered is the JR version for each yield strength variation.

6) Corus will only verify the specified impact value for this grade if asked to do so at the time of the enquiry and the order.

7)1 MPa=1 N/mm2
