Standard: EN10028-2

Material:P355GH

Equivalent: Chinese grade Q345R in GB713-2014

EN10028-2 P355GH is the European grade of high temperature pressure vessel plate. It belongs to normalized weldable fine grain steel plate. This carbon steel welding material can be used for welding.

Chemical composition(%)

C: ≤0.20, Si: ≤0.55, Mn: 1.20—1.70, P: ≤0.025, S: ≤0.010, Cu: ≤0.30, Ni: 080.08, Nb: ≤0.050 V ≤ 00.050, Ti: ≤0.030, Alt: ≥0.020, Cu + Ni + Cr + Mo≤0.70

Delivery state of P355GH plate: hot rolling, controlled rolling or normalizing/AR, CR or N.

P355GH plates should be widely used in the manufacture of steam-water separators, high-pressure heaters, deaerators, evaporators, voltage regulators and other conventional islands and motor key equipment.
