   Q460-made high-strength steel

      Q460 is a high-strength low-alloy steel. Q represents the strength of steel, 460 representatives of 460 MPa, trillion is 10 ^ 6, Pa is the pressure unit Pascal. Q460 is the steel strength of 460 MPa stress will occur when the plastic deformation, that is, when the external vent out, the steel can only maintain the shape of the force can not reply to the prototype, the strength of steel than is generally large. Q460 to ensure low carbon equivalent, based on an appropriate increase in the micro-alloying element content. Good welding performance requirements of steel with low carbon equivalent, while the increase in micro-alloying elements increase the strength of steel, it would also increase the steel's carbon equivalent. Fortunately, the increase in carbon equivalent, but very little, so it will not affect the weldability of steel.
