Hot rolled hr plate S460QL1 carbon steel plate sheet 28mm plate stock

On October 16, 2019, the Board of Directors of the World Steel Association (worldsteel) elected the following new officers for 2019/2020 at the worldsteel General Assembly in Monterrey. The new S460QL1 carbon steel plate sheet officers are elected for a one-year period: Chairman - YU Yong, Chairman, HBIS Group Co., Ltd. Vice Chairman - Sajjan JINDAL, Chairman and Managing Director, JSW Steel Limited.

S460QL1 carbon steel plate sheet controlled rolling is that, on the basis of adjusting the chemical composition of S460QL1 carbon steel plate sheet, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of S460QL1 carbon steel plate sheet.

Chemical composition of Q390C steel plate: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.7, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.10, Al ≤ 0.015. The mechanical properties of Q390C steel plate are: yield strength ≥ 390 MPa, tensile strength 470-620 MPa, elongation after fracture ≥ 18%, impact energy 34J. S460QL1 carbon steel plate sheet, Q390C steel plate is used for bridges, vehicles, ships, workshops and other large structural parts, high and medium pressure Petrochemical vessels, boiler tubes, pipes, superheaters, pressure vessels, heavy machinery, etc. application.
