Q345 steel is one kind of Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, used for a number of manufacturing purposes. To some extent, the Q345 possesses the same property and composition of ASME A572, namely the Q345 is equivalent to A572.
Q345 has good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. It is used as the structure, mechanical parts, building structure, general metal structural parts, heat, etc. bearing dynamic load for medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations, bridges, etc Used in rolling or normalizing state, it can be used for various structures in cold area below – 40 ℃.
Q345 can be divided into Q345A, Q345B, Q345C, Q345D and Q345E by grade. What they represent is that the impact temperature is different. Q345A, no impact; Q345B, impact at 20 ° normal temperature; Q345C, 0 degree impact; Q345D, is – 20 degree impact; Q345E, is – 40 degree impact. At different impact temperature, the impact value is different.
