What are the mechanical properties of Q195?
Yield strength: Thickness ≤ 16mm ≥ 195MPa, 16mm < Thickness ≤ 40mm ≥ 185MPa
Tensile strength: 315-430MPa
Elongation after fracture: ≥ 33%
Cold bending performance: No cracking after 180° cold bending
How is the weldability of Q195?
Excellent weldability, carbon equivalent < 0.3%, low tendency to weld cracks, suitable for various building welding processes such as manual arc welding, submerged arc welding, and gas welding.
How is the cold working performance of Q195?
Excellent cold bending, stamping, and shearing performance, easily processed into complex components such as purlins, wire mesh, and color steel plates for construction. Strength can be increased by 20%-40% after cold working.
How is the corrosion resistance of Q195?
Moderate corrosion resistance, prone to rust when exposed. Surface anti-corrosion treatments such as galvanizing and painting are required for building applications. Not suitable for highly corrosive building environments. What is the hardness of Q195?
It has a Brinell hardness of HB≤55, meaning it has low hardness and good plasticity, making it easy to cut and bend on-site during construction.
