S460NL steel plate belongs to the alloy special steel, this grade of steel shall be supplied to the following grades as stipulated in the inquiry and ordering: the minimum value of impact energy shall be specified when the temperature is not less than -20℃, denoted by N.
When the temperature is not lower than -50℃, the minimum shock energy is specified and expressed in ML.
Normal rolling of S460NL steel plate:
A rolling process in which the material state is equivalent to the state obtained after normalizing within a certain temperature range, the values specified in the mechanical properties of S460NL steel remain the original values even after normalizing.
