What is the density of Q195?
The density is 7.85 g/cm³, consistent with ordinary carbon steel. Construction weight calculations should be performed according to this standard.
What are the hot working properties of Q195?
It has good hot rolling properties and excellent plasticity at high temperatures, making it suitable for rolling thin plates, wire rods, welded pipes, and other profiles for construction.
What is the impact toughness of Q195?
It has good impact toughness at room temperature, but moderate toughness at low temperatures. It is not recommended for load-bearing structures in extremely cold regions and is only suitable for non-load-bearing building components.
What are the fatigue properties of Q195?
It has relatively low fatigue strength and is not suitable for dynamic load components in buildings (such as crane beams and vibrating equipment supports). It is only suitable for static load scenarios.
What is the dimensional accuracy of Q195?
The dimensional accuracy of hot-rolled profiles is generally moderate, while cold-rolled and galvanized products have higher accuracy. Dimensional tolerances for pipes and plates used in construction meet the requirements of GB/T 700 standard.
