The company has allocated special environmental protection facilities for all ASTM A514 QT steel plate pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, ASTM A514 QT steel plate steel mill scale, environmental protection dust has reached 100%.
Grade A ship steel is mainly used for the internal frame of the ship and the outer plate bearing general stress. Grade B, Grade D and Grade E ship steel ASTM A514 QT steel plate can be used for important structures in high stress areas such as hull outer plate and main deck. The Grade E ship steel has good low temperature performance, which is suitable for the hull outer plate, deck, etc. According to the minimum yield strength, the high-strength ship steel is divided into four grades: A, D, E and F. The commonly used high strength ship steels are AH32, DH32, EH32, etc.
ASTM A514 QT steel plate, Strip steel has obvious characteristics. First, it is thin and easy to bend, convenient for logistics and transportation, and saves logistics costs. Second, the surface quality of strip steel is good. Third, the strip steel is easy to process, and it can be processed only by straightening the bent part. Fourth, the strip steel has high precision and it is a good raw material for processing blades and saw blades. Strip steel is widely used in the manufacture of welded pipes, clamps, washers, spring blades, saw blades and other fields.
The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in ASTM A514 QT steel plate etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.
As to the Chemical composition, the different content is a main on carbon content, while the carbon content of ASTM A514 QT steel plate, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 grade D is 230MPa (33 ksi).
