Mechnical property for Q460C low alloy structural steel:

Chemical composition for Q460C low alloy structural steel (Heat Analysis Max%):

Q460 steel is a Chinese steel grade of Low Alloy High Strength Structural Steel, Yield Strength is 460 MPa, data is tested with 16mm diameter steel bars or steel plates, tensile strength is 550-720 Mpa, test with steel bar Ø≤40mm.
Q460 steel has much higher strength and has high comprehensive mechanical properties in normalizing, normalizing plus tempering, or quenching plus tempering, all of which are deoxidized with aluminum. It is used for large-scale engineering structures and lightweight structures that require high strength and large loads.
