P355GH Boiler grade plate
P355GH pressure vessel plate material is a kind of steel plate for high temperature pressure vessels produced according to European standard EN10028, which has excellent mechanical properties and a wide range of applications.
P355GH boiler plate has excellent mechanical properties, including:
Yield strength: between 280MPa and 355MPa depending on the thickness of the steel plate.
Elongation: P355GH boiler steel plate has good elongation properties, usually not less than 20%.
Impact toughness: P355GH steel plate can still maintain a good impact toughness.
