The yield strength of LR EH36 hull construction steel A32, D32, E32, F32 is not less than 315N/mm^2, and the tensile strength is 440~570N/mm^2. The grades A, D, E and F indicate that they can be 0 and -20 respectively. The impact toughness can reach -40℃, -60℃.
High strength steel is mainly used in offshore engineering, lifting equipment, construction machinery, container storage tank and other important steel structures with harsh working conditions, hoping to reduce weight. The application of LR EH36 hull construction steel, high strength steel can not only reduce material cost, transportation cost and production cost, but also save welding material consumption, welding work hour; reduce post welding stress, preheating temperature and post weld heat treatment requirements.
"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, LR EH36 hull construction steel Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach LR EH36 hull construction steel 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual LR EH36 hull construction steel production capacity: 3.5 million tons."
