Q390A steel plate is a low-alloy high-strength structural steel. Q in Q390A represents the yield point of the steel plate, and 390 and A represent the yield point value and quality grade.
Compared with the commonly used container plate Q345R steel plate, the strength level of Q390A steel plate has been improved, and it has higher comprehensive mechanical properties.
Delivery status of Q390A steel plate Q390A steel plate is generally delivered in the delivery state of normalizing, and can also be delivered in the state of hot rolling, controlled rolling, normalizing and tempering, cutting according to the drawing, and futures. The delivery status shall be indicated in the contract.
Application of Q390A steel plate
Q390A steel plate has good welding, cold and hot processing and corrosion resistance, and is widely used in large ships, bridges, petrochemical containers, pressure vessels, boilers, pipelines, machinery and high-load welded structural parts and other industries and has been widely praised.
