Adopt Standard EN 10028-6
Gang steel Grade: P690QL2 steel grade is quenched and tempered steel grade for weldable fine grain pressure purposes.
P355Q,P355QH,P355QL1,P355QL2,P460Q,P460QH,P460QL1,P460QL2,P500Q,P500QH,P500QL1,P500QL2,P690Q,P690QH,P690QL1,P690QL2
P690QL2 Grade has a good weldable and used in high temperature equipment and pressure vessel.
P…Q means the -20 degree and the impact energy is 27J
P…QH means the -20 temperature quality and the impact energy is 27J
P…QL1 means the -40 temperature quality and the impact energy is 27J
P…QL2 means the -60 temperature quality and the impact energy is 27J
