P460NL1 P460NL2 Boiler Quality Steel Plates
P460NL1 vessel plate is a kind of fine grain for welding low alloy high strength steel for ball tanks with minimum yield strength of 460MPa.P stands for pressure,460 stands for minimum yield strength.N indicates the delivery state of the steel plate is normalised,L1 indicates low temperature toughness series.P460NL1 vessel steel plate is one of the highest strength level of container steel developed in China at present.
P460NL2 is the pressure vessel steel plate for low temperature pressure vessel, it is the European standard vessel plate.P460NL2 is widely used in petroleum, chemical, power station, boiler and other industries, used to make reactor, heat exchanger, separator, ball tank, oil and gas tank, liquefied gas tank, boiler ladle, liquefied petroleum gas cylinders, hydroelectric power station high-pressure water pipe, turbine worm shell and other equipment and components.
