Common domestic standards include GB/T 342-2017 (Cold-Drawn Round Steel Wire), GB/T 4357-2009 (Carbon Spring Steel Wire), and GB/T 2103-2017 (General Requirements for Inspection, Packaging, Marking and Quality Certificates for Steel Wire). Export products must comply with international standards such as ASTM and JIS.

Surface scratches (mould or equipment issues), cracks (raw material defects or improper heat treatment), neck-down (unsuitable drawing parameters), bending (uneven winding tension), oxidation discolouration (poor annealing atmosphere). Strict raw material inspection and process control can minimise defects.

Both are essentially identical, referring to steel wire formed by drawing at ambient temperature. Within the industry, ‘cold-drawn wire’ is typically used for ordinary carbon steel wire, while ‘cold-drawn steel wire’ places greater emphasis on the drawing process and dimensional accuracy, commonly employed in high-precision products such as springs and fasteners. In practical applications, the terms are sometimes used interchangeably.

Production processes must treat pollutants such as pickling waste liquids and phosphating residues to meet environmental standards. Cleaner processes like cyanide-free zinc plating and chromium-free passivation should be prioritised. Environmentally friendly lubricants should be selected to reduce VOC emissions. Products compliant with international environmental directives such as RoHS and REACH possess greater market competitiveness.

Fatigue performance is critical for components like springs and steel ropes. Residual stresses and surface defects introduced during cold drawing affect fatigue life. Appropriate annealing processes, surface polishing, and shot peening enhance fatigue performance, improving product reliability and service life.

Low-carbon cold-drawn wire exhibits good weldability and can be processed via resistance welding or arc welding. Medium-to-high-carbon cold-drawn wire, with its elevated carbon content, is prone to cracking during welding. Preheating and controlled cooling are required, or suitable electrodes must be selected. For stainless steel cold-drawn wire, inert gas shielded welding is recommended to preserve corrosion resistance.

General-purpose grade permits greater diameter deviation for standard applications; medium precision grade is suitable for nails, wire mesh, etc.; fine tolerance grade is used for high-precision products such as springs and fasteners. Specify the required grade when purchasing.

Straightness is a critical parameter directly affecting machining precision. Standard cold-drawn wire must not exceed specified bending tolerances per metre (e.g., 3mm/m), with stricter requirements for high-grade wire. Production employs straightening machines or tension control during drawing to ensure product performance.

Drawing speed must be determined based on material, diameter, and equipment conditions, typically ranging from 5m/min to 60m/min. Finer gauges require slower speeds, while coarser gauges may tolerate higher speeds. Excessive speed generates heat, compromising quality; insufficient speed reduces efficiency. Modern production lines predominantly employ variable frequency speed control for precise regulation.

Common treatments include oil coating for rust prevention, electrogalvanising, hot-dip galvanising, chromium plating, phosphating, and polishing. Oil coating is suitable for short-term rust prevention; galvanising significantly enhances corrosion resistance; chromium plating increases hardness and wear resistance; polishing achieves a mirror finish; phosphating is primarily used for lubrication during the drawing process.
