Q690D material is a Chinese standard high-strength welded structural steel. What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. BV DH40 oil carrier steel, Q690D steel has high yield strength and tensile strength.
Compared with BV DH40 oil carrier steel, ordinary steel plate, ship plate has better resistance to wind and wave. In the ocean, there are often big winds and big waves. If the performance advantage of ship plate is not prominent, it is easy to be damaged by big waves. The service life of ship plate is longer than that of ordinary steel plate. Because of its excellent performance, the ship plate can be used for a long time. Some waste ships can remove the ship plate for recycling. The price of ship plate is higher than ordinary steel plate.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of BV DH40 oil carrier steel nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of BV DH40 oil carrier steel steel, can be used as an alloying element of low alloy steel.
