P355NL2 steel plate is a European standard container steel plate that implements EN10028 standard. It belongs to the brand of Wugang Science and Technology Department and can be welded by normalizing fine grain steel plates. There are four grades: P355N (room temperature), P355NH (high temperature), P355NL1 (low temperature), and P355NL2 (special low temperature). P355NL2 container plates are commonly used in petroleum, chemical, boiler and other industries to manufacture reactors, separators, boiler drums and other equipment and structural parts.
