Supply EH40 shipbuilding plates

The composition of EH40 shipbuilding plates are designed and then simulating smelting in vacuum induction furnace. Three EH40 steel ingots which the composition meets the target requirement is got. The composition are average for：0.081wt% C,0.309wt% Si, 1.332wt% Mn, 0.0060wt% P, 0.0040wt% S, 0.0250wt% Als. 0.034wt% Nb, 0.014wt% Ti.

The properties of EH40 shipbuilding plates which produced by the optimum process meet the requirement of GB very well. The yield strength are 540MPa both in crosswise and lengthways, and the tensile strength are 620MPa in crosswise and 622MPa in lengthways, and the elongation are 25% in crosswise and 29.5% in lengthways, and the Akv are 196J at -20℃, 184J at -40℃, 159J at -60℃ in the crosswise and 243J at -20℃, 259J ate -40℃, 223J at -60℃ in the lengthways. And the microstructures are main polygons or quasi polygons ferrite, a small acicular ferrite and pearlite. Fracture morphology of low-temperature impact is all typical ductile fracture.

In order to adapt to the needs of development of marine industry, the shipbuilding plate, which owns high strength, good low-temperature impact toughness and good extension performance, is developed.
BBN steel is specialized in supplying EH40 shipbuilding plates. We have 17 years experience in the exportation of EH40 shipbuilding plates. and other steel such as AH36 also available. Please feel free to contact us.
