A514 steel plate is high strength weldable steel quenched and tempered according to ASTM standard. ASTM A514 steel plate is mainly used in places where NV D container barge steel high tensile strength and high yield are required. The lifting gears of engineering vehicles, and racks for offshore platforms generally use A514 grade Q or A514 Gr Q. The NV D container barge steel hardness of A514 steel plate is between 235-290. A514 steel yield strength is more than 630MPa, and tensile strength is more than 700MPa. A514 steel plate is difficult to process. In the United States, the use of A514 steel plate is very large.

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, NV D container barge steel, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

The strength level of traditional spring steel is difficult to meet the requirements of modern industrial development. As we all know, the mechanical properties of NV D container barge steel, spring steel depend on the heat treatment process under the premise of material quality assurance, and the heat treatment process should also be determined according to the material itself. An important way to increase the strength of spring steel is to give full play to the role of alloying elements to achieve the best alloying effect.
