P355GH Pressure vessel steel plate which according to standard EN 10028-2 are mainly specified in elevated temperature working surroundings and normally used to low strength welded boilers and pressure tanks&vessels. P355GH is a pressure vessel steel grade as specified under the Euro Norm standard which has superseded British Standard and DIN standard equivalents.

With the yiled strength at 355 Mpa, EN 10028-2 P355GH Pressure vessel steel plate shall be done heat treatment under Normalised.For the additional technicals,SPWHT-Simulated Post Welded Heat treatment and Ultrasonic test,P355GH steel plate is normally adopted.
