EN10028-2 boiler pressure vessel steel plate

P235GH steel plate is belong to the EN 10028-2 boiler steel pressure vessel and boiler steel plate/coil. And P235GH steel plate is widely used in the fabrication of boilers and pressure vessel, such as petroleum, chemical, gas industry and power plants.

P235GH steel plate is also a heat-resistant pressure vessel steel defined in the EN 10028-2 boiler steel system. Similar to P235GH steel plate, but lower carbon content and higher manganese content. Compared with P235GH steel plate, the yield rate and tensile strength of P235GH steel plate are lower.
