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.
Under pressure vessel steel standard EN 10028-3, steel grade P460NL1 shall be done normalization and low temperature impacting test.
