EN10028-2 P355GH Pressure Vessel Steel Plates
P355GH belongs to medium pressure boiler steel plate.P355GH vessel plate is the yield strength of 265-345MPa level of pressure vessel special plate, it has good comprehensive mechanical properties and process performance. Phosphorus, sulfur content is slightly lower than the low alloy high-strength steel plate, in addition to tensile strength, elongation requirements than the P355GH steel has improved, but also to ensure the impact toughness.
Delivery status of P355GH steel boiler plate: hot rolled, controlled rolled or normalized/AR, CR or N.
