P355GH steel plate application:
EN10028 P355GH steel plates is a kind of material for boiler and pressure vessel steel. EN10028 P355GH steel plates is characterised by a minimum yield strength of 280-355 MPa and by good weldability,so P355GH steel is mainly used to for manufacturing boilers, pressure vessels and pipes transporting hot liquids.
