The difference between Q460NC steel plate and Q460C, the thickness performance of Q460NC steel plate is more than 80
The difference between Q460NC steel plate and Q460C is that the thickness of Q460NC steel plate is more than 80, and the normalized rolling plate Q460NC steel plate is a low-alloy high-strength steel. The Q in the grade of Q460NC represents the yield strength of the steel. Capital letters; 460 stands for 460 MPa, mega is 10 to the 6th power, and Pa is the pressure unit Pascal; Q460 means that plastic deformation will only occur when the mechanical strength of the steel reaches 460 MPa, that is, when the external force is released, Steel can only maintain the shape of the force and cannot return to its original shape, which is stronger than ordinary steel. N stands for normalizing or normalizing rolling, C—quality grade is C (grades are divided into C, D, E).
