S355NL steel plate is a European standard alloy structural high strength steel. S355NL steel plate is a normalized rolled weldable fine grain structure steel plate. S means structural steel, N means state. L indicates the grade of the minimum value of impact energy when the temperature is not lower than -50°C.
S355NL steel plate implements standard EN10025-3.
