Introduction of P355GH grade of European standard container plate

P355GH is a European standard container plate, the implementation standard: EN10028, according to the CEN/CENELEC internal regulations, the European standard container plate, the implementation standard: EN10028 (European steel plate standard for pressure vessels). P355GH belongs to the steel plate for medium pressure boiler, and P355GH belongs to the

steel plate for medium pressure boiler. It is a kind of steel plate for European pressure vessels, which is equivalent to the domestic Q345R (16MnR EN10028). According to the CEN/CENELEC internal regulations, the following countries implement the standard: EN10028 (European standard for steel plates for pressure vessels).
P355GH Steel Plate Delivery Condition: Hot Rolled, Controlled Rolled or Normalized/AR, CR or N.

(1): The Ca value is for reference only, not as an acceptance condition, and the Ca and O content can be replaced by the finished product analysis value.
(2): The formula for calculating carbon equivalent (CE) is as follows: CE=C+Mn/6+(Cu+Ni)/15+(Cr+Mo+V)/5.
(3): The data comes from the network, for reference

only, P355GH steel plate is a special plate for pressure vessels with a yield strength of 265-345MPa, which has good comprehensive mechanical properties and process properties. The phosphorus and sulfur content is slightly lower than that of low-alloy high-strength steel plate, in addition to the tensile strength and elongation requirements are higher than that of P355GH steel, and the impact toughness is also required to ensure that it has good plasticity, toughness, cold bending performance and welding performance, and is suitable for the manufacture of nuclear island steel containment, pressure vessels, and equipment components.
