Q460 is a kind of high strength low alloy steel.. Q represents the strength of the steel, 460 on behalf of 460mpa, mega is 10 to the power 6, pa is PASCAL pressure units. Q460 is that steel occurs when the stress strength of 460mpa plastic deformation. That is to say when the external force drain off after the steel base can only maintain the shape of the stress and cannot be undone, this intensity is bigger than general steel.

On the bases of low carbon equivalent, Q460 appropriate to increase the content of micro alloying elements.Good welding performance of steel requires low carbon equivalent, and the increase of micro alloying elements in steel strength at the same time, also increase the carbon equivalent of steel.But fortunately, very few increase of carbon equivalent, so will not affect the weldability of steel.
