Q690D steel plate belongs to low-alloy high-strength structural steel plate. The implementation standard of Q690D steel plate is the special technical condition of GB/T1591-2008.
Q690D steel plate is delivered in quenched and tempered state, the yield strength of Q690D steel plate is greater than or equal to 690MPa, and the tensile strength is between 770MPa-940MPa. Q690D steel plate has good cutting and welding performance, and has strong anti-fatigue performance. It is often used as a special workpiece of mechanical equipment, or used as a spare part of high-frequency vibration equipment.
Q690D steel plate itself not only has very high strength but also has certain flexibility, wear resistance, fatigue resistance, impact resistance, easy processing and wear resistance.
Therefore, Q690D steel plates are often used in manufacturing industries, such as mining machinery, cranes, iron anchors, shield machines, hydraulic supports, port machinery, marine equipment bridge structures, etc.
