Q235 - What cutting methods are suitable?
A: Flame cutting, plasma cutting, laser cutting, shearing machine cutting, and excellent gas cutting performance.
Q235 - What are its cold bending properties?
A: Excellent. It can be cold-bent 180° without cracking, suitable for bending, rolling, and stamping.
Q235 - What are the precautions for stamping?
A: Low-carbon steel has good plasticity, but springback needs to be controlled; preheating is recommended for thick plate stamping.
Q235 - Is it prone to deformation during processing? How to control it?
A: Welding/cutting is prone to heat deformation; use segmented welding, fixture fixing, and cooling control to reduce deformation.
Q235 - Can it be heat-treated?
A: Generally, quenching/tempering is not done (low-carbon steel has poor hardenability); stress-relief annealing can be used only when stress relief is needed.
