EN10025-6 S500QL1 steel plates is belong to EN10025-6 hot rolled products of structural steels Technical delivery conditions for flat products of high yield strength structural steels in the quenched and tempered condition
The S500QL1 steel making process shall be in accordance with EN 10025-1. If specified at the time of the order the steel making process shall be reported to the purchaser.
The S500QL1 steels specified in this document shall be fully killed. The steels shall have a fine grain structure containing nitrogen binding elements in amounts sufficient to bind the nitrogen.
The S500QL1 designation shall consist of:
− the number of this document (EN 10025-6);
− the steel name or the steel number; the steel name consisting of:
− the symbol S (for structural steel);
− the indication of the minimum specified yield strength for thickness ≤ 50 mm expressed in MPa1);
− the delivery condition Q;
− the capital letter L or L1 for the quality with specified minimum values of impact energy at temperatures not lower than -40 °C or -60 °C.
EXAMPLE S500 Structural steel (S) with a specified minimum yield strength at ambient temperature of 500 MPa1), in the quenched and tempered delivery condition (Q) :
Steel EN 10025-6 – S500QL1
When S500QL1 products are supplied with a control on Si e.g. for hot-dip zinc-coating so that there could be a need to increase the content of other elements like C and Mn to achieve the required tensile properties, the maximum carbon equivalent values of Table 4 shall be increased as follows:
− for Si ≤ 0,030 %, increase CEV by 0,02 %;
− for Si ≤ 0,25 %, increase CEV by 0,01 %.
S500QL1 Tolerances on dimensions and shape shall be in accordance with the requirements given in the order by reference to the relevant documents according to 2.2 and according to 2.2 and 7.7.1 of EN 10025-1:2004.
For hot rolled plate tolerances the basic requirements shall be in accordance with EN 10029, including thickness tolerances to class A, unless otherwise agreed at the time of the order.
