Grade DH36 ship steel plate is a high-strength ship plate. Shipbuilding steel generally refers to the steel used for hull structure. It refers to the steel used for manufacturing the hull structure produced in accordance with the requirements of the classification society construction codes. A514 Gr P QT steel plate, DH36 ship steel plate is often ordered, scheduled, and sold as special steel. We can supply various sizes and shapes of ship steel like plates , steel angles, bulb flat, steel channel and section steel.
Our company has A514 Gr P QT steel plate strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply A514 Gr P QT steel plate deep processing service for products A514 Gr P QT steel plate like cutting, drilling, bending, welding and grinding.
A514 Gr P QT steel plate annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of A514 Gr P QT steel plate annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. A514 Gr P QT steel plate annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
Alloy steel plate is formed by adding alloy elements into steel. In this process, the basic elements of steel, namely iron and carbon, will have a certain effect with the newly added alloy elements. Under this effect, the structure and material in the steel will have certain changes, and the overall performance and quality of steel will also be improved. Therefore, the output of A514 Gr P QT steel plate, alloy steel plate is increasing, and its application range is more and more extensive.
