P460ML1 and P460ML2 boiler steel plate
Source:Yusheng steel
Pressure vessel steel plate and sheet P460ML1 and P460ML2 under European standard EN 10028_6 shall be done heat
treatment with thermomechanically rolled when production.Until now,there is no sufficient data for the standardization
of the elevated temperature properties of steels P460ML1 and P460ML2.So if their use at such temperatures is intended
the conditions for this should be specially agreed between the interested parties.
For boiler steel plate P460ML1,low temperature impacting test shall be done at minus 40 centi degree,and boiler steel
plate P460ML2 have to be done at minus 50 centi degree.For all the steel plates for pressure vessels and boilers,our mill
compulsively do the Ultrasonic examation at least according to A435/A435M.This would be for safety end using.
