What is the Q460C steel meaning?

Q460C steel plate is a low-alloy high-strength steel. Q represents the strength of steel, and 460 represents 460MPa. Q460C means that the plastic deformation of steel will only occur when the strength of the steel reaches 460 MPa, that is, when the external force is released, the steel can only maintain the shape of the force and cannot return to its original shape. This strength is greater than that of ordinary steel.

Q460C steel meaning:

Q—The first letter of the Chinese Pinyin of "qu" for the yield strength of steel;

460—Yield strength value, unit MPa;

C—The quality grade is D grade (the grade is divided into C, D, E).

When the client needs the steel plate to have thickness direction performance, add the symbol representing the thickness direction (Z direction) performance level after the above-mentioned grade, for example: Q460CZ15.
