Q420HD steel plate is a steel plate for nuclear power. Consider receiving the effect of neutron radiation for a long time, because the more alloy elements, the weaker the overall anti-neutron radiation ability. Generally, the sparse alloy element steel with strong anti-radiation ability is selected. Mn-Ni-Mo series low-alloy high-strength steel.
Application:
Because Q420HD steel plate has suitable strength, high toughness and low brittle transition temperature (NDT), good structure stability, weldability, cold and hot workability and fatigue strength, this Q420HD steel plate will be frequently used in Manufacturing of nuclear power equipment.
