Q195's impact toughness?
A: Good impact toughness at room temperature, suitable for cold working such as stamping and bending at room temperature.
Q195's weldability?
A: Excellent weldability, carbon equivalent <0.3%, thin plate welding at room temperature requires no preheating, can be done with E43 series welding electrodes and CO₂ gas shielded welding.
Q195 is suitable for which welding methods?
A: Applicable to conventional methods such as arc welding, resistance welding, CO₂ welding, argon arc welding, and submerged arc welding.
Q195's cold working performance?
A: Limiting deep drawing coefficient is approximately 0.55, minimum bending radius is 0.5t, easy to stamp, draw, and bend, suitable for deep-drawn parts.
Q195 requires heat treatment?
A: Usually delivered in hot-rolled condition without heat treatment; only for special requirements (such as stress relief) can low-temperature annealing (500~650℃) be performed.
