Q345 is a kind of steel. It is a kind of low alloy steel, which is widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment, etc. where "Q" means yield strength, 345 means that the yield strength of this steel is 345mpa. The yield value of Q345 will decrease with the increase of material thickness, and the domestic one may be less than 345mpa, so the strength must be less than 345mpa in mechanical design, otherwise there will be problems. Q235 - metal structural parts, carburized or cyanide parts with low core strength requirements, pull rods, connecting rods, hooks, couplers, bolts, nuts, sleeves, shafts and weldments
Q345 -- good comprehensive mechanical properties, low temperature performance, good plasticity and weldability. It can be used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. It can be used in hot rolling or normalizing state. It can be used for various structures in cold areas above - 40 ℃。
