A131 AH420/DH420/EH420/FH420 steel plate/sheet


A131 AH420/DH420/EH420/FH420 apply to weldable high strength and tempered steel plates and wide flats up to 70 [mm] thickness. The application of these requirements for products with thicknesses above 70 [mm] and for product forms other than plates and wide flats such as sections and tubulars, are to be specially agreed.The steel covered by the scope of these requirements are divided into six yield strength levels of 420, 460, 500, 550, 620 and 690 [N/mm2]. For each yield strength level four grades AH, DH, EH and FH are specified, based on the impact test temperature.
