P460NL1 STEEL PLATE

Under pressure vessel steel standard EN 10028-3,steel grade P460NL1,P460NL1 steel plate,P460NL1 steel sheet shall be done normalised and low temperature impacting test.For all the steel plates for pressure vessels and boilers,such as P355NH,P355N,P460NH,P460NL2,our mill compulsively do the Ultrasonic examation at least according toA435/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.Other ultrasonic test standard also can offered by us as EN 10160 S0E1,S2E2,S2E3,S3E3,S3E4.
