General grades A, B, D and E are distinguished according to the impact temperature of the steel. The impact value of each grade of steel is the same. Preheating requirements for high strength hull structural steel: for the thickness of ABS EH36 steel plate greater than 30mm, the butt joint should be preheated to 120 ~ 150C before welding.
The ABS EH36 steel plate dimensions range
Thickness Range: 5 mm -150 mm
Width Range: 1500 mm - 3900 mm
Length Range: 6 m, 12 m, coils
The thickness of ABS EH36 steel plate is 30mm, and the ambient temperature is below 5℃ and preheated to 75℃; when the ambient temperature is below 0℃, preheat the ABS EH36 steel plate to 75 ~ 100℃.
For ABS EH36 steel plate, good low temperature toughness and good welding performance are required. The production of ABS EH36 steel plate needs to be standardized by controlled rolling and controlled cooling or heat treatment process, and the equipment is more complete. At the same time, the purity of steel inside the billet is required to be high, especially the content of S, P, N, O, H in ABS EH36 steel plate is strictly controlled.
