What is the material of Q460C steel?

Q460C steel is a kind of low-alloy high-strength steel. The yield strength of Q460C steel is relatively high, and it can be plastically deformed when the force strength of the steel reaches 460 MPa, and it will maintain the force shape after the external force is removed. The content of microalloying elements in Q460 has increased, so the welding performance of this material is better and the strength is higher. Among them, Q represents the yield strength, 460 represents the value of the yield strength, which is 460 MPa, and C represents the quality level, which is C level. The quality level is divided into three levels: C, D, and E.

Q460C steel has higher strength, and has higher comprehensive mechanical properties during normalizing, normalizing and tempering, or quenching and tempering, all of which are deoxidized with aluminum. Q460C steel is used for large engineering structures and light structures that require high strength and large load.
