Q195 Surface Quality and its Impact on Nail Making?
No scabs, no cracks, and a thin iron oxide scale (≤0.02mm); otherwise, the drawing die wears quickly, resulting in more wire breakage and a poor finished product surface.
Q195 Thickness/Specification Selection?
Wire: 5.5–6.5mm wire rod cold-drawn to 1.2–10mm; Steel Plate: 1.5–3mm cold-rolled/hot-rolled plate, used for stamping nails/steel strip wire cutting.
Q195 Wire Rod → Nail Manufacturing Process?
Wire rod → Pickling/Shelling → Multiple Cold Drawings (to target diameter) → Straightening and Cutting → Cap Making/Pointing → Surface Treatment → Packaging.
Q195 Cold Drawing Requires Annealing?
Large deformation (e.g., 5.5→1.2mm) requires intermediate annealing to eliminate work hardening and prevent wire breakage; small deformation can be directly cold-drawn.
Q195 Cap Making is Less Prone to Cracks.
It has good plasticity and high elongation, low stress in the transition zone between the nail shank and the cap, and a fracture rate of <0.1%, making it suitable for high-speed nail making machines.
