The standard specifies seven steel grades, and their yield strength at ambient temperature is different. All steel grades to be supplied in the following steps shall be established when required. The specified minimum value of impact energy when the weather is not lower than – 20 �� (no label). When the temperature is not lower than – 50 ��, the specified minimum value of impact energy is expressed in L. (except for s960), the minimum amount of impact energy set when the temperature is not lower than – 60 �� is defined as L1. In quenching and tempering delivery conditions (q) and grade L: Steel en 10025-6-s460ql; or steel en10025-6-1.8906.
