EN10028-5 standard specification for weldable fine grain steels, thermomechanically rolled boiler steel plate. It covers steel grade P355M, P355ML1, P355ML2, P420M, P420ML1, P420ML2, P460M, P460ML1, P460ML2.
P355ML1 is a thermo mechanically rolled and weldable fine grain steels grade. The dimensions and tolerance on dimensions should be according to EN 10028-1. P355ML1 Grade usual be used for pressure equipments.
P…M mean the -20 degree and the impact energy is 27J
P…ML1 means the -40 temperature quality and the impact energy is 27J
P…NL2 means the -50 temperature quality and the impact energy is 27J
