P460QH pressure vessel plate
P460QH vessel steel plate belongs to a kind of European standard alloy vessel plate, the implementation of the technical standard is EN10028-6, often used in the manufacture of pressure vessels.
P460QH boiler steel plate is generally delivered in different states such as quenched+tempered (i.e. tempered), normalised and so on, and can be delivered in different states according to customers' specified requirements.
The yield strength and mechanical strength parameters of P460QH pressure vessel steel can meet the requirements of the EN10028 technical standard, and can be produced in fixed laminations according to the corresponding values.
