P355GH pressure vessel steel plate process and ordering instructions
The elongation at break of the high-temperature tensile test is recorded as a reference. The impact absorption energy at -20 and -40 of the impact test shall meet the requirements of Table I in the Annex. §8.6 Ultrasonic inspection must be carried out in accordance with AFNOR standard NF A04-305: ——For steel plates of class 1 equipment: the scan chart C standard in this standard must be used to inspect only parts with a minimum thickness of 12mm. In addition, as stated in 5.2.2 of the standard, a test must be performed in the weld zone on the same edge as the steel plate. ——For Grade 2 equipment steel plates: In accordance with this standard drawing and Grade B guidelines, only parts with a minimum thickness of 30mm are inspected.
