Why is Q195 so ductile?
Its low carbon content gives it excellent cold bending, stamping, and tensile properties, making it less prone to cracking and suitable for bending and forming processes.
How is the weldability of Q195?
It has excellent weldability. Its low carbon content and low impurities result in a low tendency for weld cracking, making it suitable for arc welding, resistance welding, etc., producing reliable joint strength.
Can Q195 be heat-treated?
Generally, quenching is not recommended (as the effect is poor). Strength can be increased through cold rolling and cold drawing, but this will reduce ductility.
How is the corrosion resistance of Q195?
It has moderate atmospheric corrosion resistance and is prone to rusting in humid environments, requiring surface treatments such as galvanizing and painting.
How do the properties of Q195 change after cold working?
Cold drawing/cold rolling increases strength but decreases ductility, commonly used for making steel wire and cold-rolled sheets.
