P355GH steel

P355GH steel plate, 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.the following are EN10028P355GH steel plate's Chemical composition and mechanical properties.
