Introduction and application of A514Grh steel plate grade
Introduction to A514Grh steel plate grades A514GrH and A514GrF belong to
high-strength weldable structural steel plates, with the same series of grades: A514 GrA, A514GrB, A514GrE, A514GrF, A514GrH, A514GrP, A514GrQ, A514Gr.S. A514GrH and A514GrF steel plates have high tensile and yield properties, and are often widely used in lifting gears for engineering vehicles and racks for offshore platforms

Note:
(1): In order to improve the properties of steel, other trace alloying elements other than those in the above table can be added; This value is only for WSD690D≤80mm; The data comes from the network and is for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the requirements of
GB/T222 A514Grh steel plate smelting The steel plate should be heat treated, and the steel plate should be heated to no less than 900, quenched in water or oil, and tempered at no less than 620. The heat treatment temperature should be recorded in the test report. The ordered steel plate is not heat treated according to rule 3.1 and should be strained by the manufacturer.
A514GrH, A514GrF steel plate materials and manufacturing steel should be calmed steel, and should meet the fine austenite grain size requirements of A6/A6M
