VL E460 steel: is a structural steel plate for ships and offshore engineering."VL" stands for the abbreviation of "DNVGL", which is a standard certified by the two classification societies of DNV (Norway) and GL (Germany). The yield strength is 460. Different classification society certifications, different grade requirements and different yield strengths can be selected according to different needs.

Oxygen is a harmful element in marine grade LR FH40 hull steel plate steel. With the increase of oxygen content, the strength of marine grade LR FH40 hull steel plate steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of marine grade LR FH40 hull steel plate steel.
