P235GH steel

P235GH steel plate, EN10028 P235GH steel plates is a kind of material for boiler and pressure vessel steel. EN10028 P235GH steel plates is characterised by a minimum yield strength of 170-230MPa and by good weldability,so P235GH steel is mainly used to  for manufacturing boilers, pressure vessels and pipes transporting hot liquids.the following are EN10028 P235GH steel plate's Chemical composition and mechanical properties
