EH32 Shipbuilding Steel Plate
EH32 steel grade is lower than FH32 in yield and tensile strength. It is a good material for shipbuilding in deck. EH32 Grade is in -40 impact test of 34J energy. All of thickness of EH32 material need normalize in delivery station.Shipbuilding grade EH32 is the high tensile strength steel, EH32 steel for shipbuilding and oil platform must be good toughness properties, higher strength, strong corrosion-resistance, the processing properties, and welding properties.
