Cold Drawn Wire for Nail Production
Cold drawn wire is a steel wire product manufactured by cold drawing process of wire drawing machine. It has high strength and surface quality and is usually used to manufacture fasteners, springs, wire ropes and various construction and industrial purposes.
Cold drawn wire used to produce nails must have specific mechanical properties and surface quality to meet the production requirements and use performance of different types of nails. Commonly used cold drawn wires in nail production are Q195, #45, #60, SAE1008, SAE1018, SAE1026, SAE1035, 08AL, C1022 and 304 stainless steel, etc. Different steel wire and processes need to be selected according to the type and use of nails. The following are the cold drawn wire material selection and characteristics for several common nail types:
- Common Wire Nails
Material: Q195, SAE1008, and SAE1018 low carbon steel.
Features:
Q195: Carbon content is about 0.06-0.12%, with good ductility and toughness, easy to process.
SAE1008: Carbon content is about 0.08%, suitable for making small, flexible nails.
SAE1018: Carbon content is about 0.18%, which is higher strength than SAE1008 and is suitable for making larger nails.
- Concrete Nails
Material: #45 or #60 high carbon steel
Features:
#45 steel: Carbon content is about 0.45%, with high hardness and strength after quenching, suitable for harder materials.
#60 steel: Carbon content is about 0.60%, has higher strength, and is suitable for hard concrete.
- Screw Nails
Material: 08AL, C1022, 304 stainless steel
Features:
08AL: Low carbon steel, low carbon content (about 0.08%), easy to cold form, suitable for making ordinary screws.
C1022: Medium carbon steel, carbon content is about 0.22% and has high strength and corrosion resistance after heat treatment.
304 stainless steel: Excellent corrosion resistance, containing 18% chromium and 8% nickel, suitable for humid and corrosive environments.
Nail Production Process Steps
- Wire Selection
Choose appropriate wire rod (such as Q195, #45, 08AL, etc.) according to the purpose of the nail.
- Wire Drawing Process
The straight line wire drawing machine is used to draw the steel wire to the required diameter through a series of gradually reduced wire drawing dies to ensure the surface finish and dimensional accuracy.
- Annealing Treatment (if necessary)
Annealing is performed after wire drawing to soften the cold drawn wire and improve toughness, such as high carbon steel cold drawn wire for concrete nails.
- Nail Making Process
Use a nail making machine to process the cold-drawn wire into nails.
- Heat Treatment (if necessary)
Heat treatment is performed on nails that need to improve hardness and strength (such as concrete nails) – the nail is heated to a high temperature and then quickly cooled to harden it and improve its strength..
- Surface Treatment (if necessary)
Galvanizing, plastic coating, and other surface treatments are performed as needed to improve the corrosion resistance of the nails.
Conclusion
When choosing cold drawn wire for nail production, the mechanical properties of the material, the processing technology, and the final use must be considered comprehensively to ensure that the nails meet their use requirements.
