P355GH P295GH Pressure Vessel steel plate and sheet

Source:Yusheng steel

 

Under EN 10028-2,there are two main steel grades P355GH and P295GH are mainly used as pressure vessel and boiler steel plates and sheets by end users.With the yiled strength at 355 Mpa,P355GH steel plates shall be done heat treatment under Normalised.For the additional technicals,SPWHT-Simulated Post Welded Heat treatment and Ultrasonic test,P355GH steel is normally adopted.

 

P295GH steel plate is at minimum 295 Mpa for yield strength,and tensile strength shall be within 460-580 Mpa for the thickness belows 100 millimeters.The delivery condition of steel P295GH shall be under Normalized when rolling.Now YUSHENG STEEL give customers the details of steel property for P355GH steel sheet:
