Q460C steel plate is a low-alloy high-strength steel. Q in Q460C steel plate represents the yield strength of steel; 460 represents 460 MPa, mega is 10 to the 6th power, and Pa is the pressure unit Pascal; Plastic deformation will only occur at 460 MPa, that is, when the external force is released, the steel can only maintain the shape of the force and cannot return to the original shape. This strength is greater than that of ordinary steel. C—The quality grade is C grade (grades are divided into C, D, E).
The implementation standard of Q460C steel plate is GB/T1591-2018 low-alloy high-strength structural steel standard and GB/T16270-2009 high-strength structure quenched and tempered steel plate standard.
The delivery state of Q460C steel plate is delivered in the state of hot rolling, normalizing, normalizing rolling, thermomechanical rolling (TMCP) or quenching and tempering.
The smelting method of Q460C steel plate is that steel is smelted by converter or electric furnace, and can be refined outside the furnace if necessary.
