P355QH material is a hardenable and tempered weldable fine-grain steel, which is a basic steel plate. Standard: EN10028-6, digital number: 1.8867, P355QH is a professional alloy steel, steel for pressure equipment, with good plasticity, toughness, cold bending performance and welding performance.

The P355QH steel plates size, shape and allowable deviation of the steel plate should meet the requirements of EN10028-1 2007+A1:2009.
P355QH steel grade is quenched and tempered steel grade for weldable fine grain pressure purposes.
P355QH Grade has a good weldable and used in high temperature equipment and pressure vessel.
