P460NL1 and P460NL2 boiler steel plate
Source:Yusheng steel
Under EN10028_3 standard steel plate P460NL1 and P460NL2 are steels for pressure purposes and mainly used for
manufacturing pressure vessels and boilers and tanks.Weldable fine grain steels P460NL1 and P460NL2 have to be
done Normalized when processing in mill.Pressure vessel steel P460NL1 shall be done low temperature impacting test
at Minus 40 centi degree,Pressure vessel steel plate P460NL2 shall be done special low temperature impacting test 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.For the tensile strength of P460NL1 at thickness above 100 millimeters,
the values shall be specified in the purchase order by our customers.
