S355NL normalized steel has different impact energy requirement for impact tests at different temperature environment. S355NL plate shall be done impacting test in longitudinal direction under -50℃ with the minimum energy 27J. When customers request done charpy_V notch test under -20℃,then the impacting energy shall be above 47J. For the transverse direction,the engery shall be above 16J under the temperature -50℃. The A573 Gr.58 steel and S275NL steel comparison, steel Grade S355NL making process shall according to EN10025-1.
