What are the core mechanical properties of Q195?
Yield Strength: ≥195MPa for ≤16mm, ≥185MPa for 16-40mm
Tensile Strength: 315-430MPa
Elongation (δ5): ≥33% for ≤16mm, ≥32% for 16-40mm
7. What are the plasticity and toughness of Q195?
Extremely high plasticity, elongation ≥33%, easily cold-bent and stamped; good toughness, strong impact resistance at room temperature, suitable for complex processing.
8. What are the weldability of Q195?
Excellent weldability, low carbon content reduces the risk of welding cracks, suitable for conventional processes such as arc welding, gas welding, and resistance welding, with stable weld joint strength.
9. Is Q195 suitable for cold working or hot working?
It is suitable for both cold and hot working, with superior cold working performance (bending, stamping, cold drawing), which is its core advantage; hot working (hot rolling, forging) can also be performed normally.
10. What is the machinability of Q195?
The machinability is average. Due to its high plasticity, it is prone to tool sticking, making it suitable for low-speed cutting. Appropriate tool selection and cutting parameters are necessary during machining.
