Q460E grade steel is used as high-strength steel structural parts for engineering and general structures that require impact performance at low temperature-40. Q460 is also a low-alloy high-strength steel with elongation ≥17%.
Q represents the strength of steel, and 460 represents 460MPa. Q460 means that the plastic deformation of steel will only occur when the strength of the steel reaches 460MPa, that is, when the external force is released, the steel can only maintain the shape of the force but cannot return to its original shape. This strength is greater than that of ordinary steel.
On the basis of ensuring low carbon equivalent, Q460E steel plate appropriately increases the content of microalloying elements. Good welding performance requires low carbon equivalent of steel, and the increase of microalloying elements will increase the strength of steel while also increasing the carbon equivalent of steel. Fortunately, the added carbon equivalent is very small, so it will not affect the weldability of the steel.
Application range:
Q460E steel plates are mainly used to manufacture bridges, ships, vehicles, boilers, high-pressure vessels, oil and gas pipelines, large steel structures.
