The raw material of Q460D steel plate is carbon steel, which belongs to the low alloy series in category, and the impact temperature is -20°C. Q460D steel plate is a low-alloy high-strength material. The steel number of Q460 steel plate is prefixed with "Q", which represents the yield point of the steel plate, and the number behind it indicates the value of the yield point, and the unit is MPa. D is -20 degree impact.
The Q460 steel plate is subjected to the heat treatment process of hot rolling.
The implementation specification of Q460 steel plate is GB/T 3274-2007 carbon structural steel and low alloy structural steel hot rolled thick material and steel strip.
Specification for chemical composition of Q460 steel plate: GB/T 1591-2008 low-alloy high-strength structural steel.
This kind of raw material is generally more in the steel structure. Q460 steel plate has high comprehensive mechanical properties after quenching and tempering treatment.
Q460 steel plate is mainly used in various large engineering structures and light structures requiring high strength and heavy load.
