What is P355NL2 steel plate

P355NL2 steel plate is European standard vessel steel plate, which is normalized and weldable fine grain steel plate. There are four grades: P355N (room temperature), P355NH (high temperature), P355NL1 (low temperature) and P355NL2 (special low temperature). P355NL2 vessel plate is often used in petroleum, chemical, boiler and other industries to manufacture reactor, separator, boiler drum and other equipment and structural parts.

The dimension, shape and allowable deviation of P355NL2 steel plate shall meet the requirements of 2007+A1:2009 in EN10028-1.
