SparkX- Leading Stainless Steel Wire Manufacturer in China
Stainless steel wire is commonly used in springs, metal mesh and even medical devices and aerospace applications. SparkX provides stainless steel wire diameters of Ø0.10–8.00 mm (larger on request), with tempers from soft or annealed to spring hard. Surface options include bright drawn or bright annealed and soap-lubed. Certainly, we control diameter tolerance down to ±0.003–0.015 mm by size, and check cast and helix to ensure smooth string laying. We provide DIN spools or carrier coils with full traceability and EN 10204 3.1. Grades include 302/304/304L/316/316L/321/430, 302HQ(304Cu) for cold heading, and 17-7PH for high-strength springs. If you want to choose others, please contact us.
Our wire production is supported by upstream melting and wire-rod production within the group, followed by drawing, annealing, surface control and final inspection. This integrated route gives us greater flexibility for chemistry, temper, diameter tolerance and batch consistency requirements.

High strength wire commonly used for springs and forming, can maintain elasticity and fatigue performance in cold drawn conditions.
Widely used wire suitable for weaving and fabrication, 304L improves welding performance and reduces sensitization for welding.
High temperature stabilized wire, not easily sensitized after heating and maintains excellent performance in thermal cycling.
Ferritic wire with magnetic and good oxidation resistance, economical and suitable for straightening, bundling and general forming.
Specially designed for cold heading, has excellent screw, rivet and fastener forming properties and good heading stability.
Stainless Steel Wire Processing: Drawing, Annealing & Cleanliness
The stainless steel wire undergoes multiple cold drawing passes and precise lubrication. Followed by bright annealing or maintaining a bright drawn state as required. For spring and forming, a clean and uniform surface can avoid die galling and stabilize pitch. We can control residual lubricant to a target level and provide passivation when needed. For welding or braiding feed, tight cast and helix minimize birds nesting and cut scrap.
Stainless Steel Wire Tempers and Tolerances
Tempers range from soft, 1/4 hard, 1/2 hard, hard, to spring temper. We lock tensile windows suitable for CNC coilers. Typical tolerances ±0.003–0.005 mm at Ø≤0.30 mm, ±0.005–0.010 mm at Ø0.30–1.00 mm, ±0.010–0.015 mm at Ø1.00–3.00 mm, tighter by agreement. Cast and helix are checked according to ASTM A313/A580 or EN 10270-3 so your payoff is steady and tooling life is stable.
Stainless Steel Wire-Spools, Coil Weight & Packing
We supply DIN200, 250, 355, 400, 500 spools and Z2, Z3 spools or carrier coils 250-1000kg. Other small coils, such as 5-25kg, are also available. We mark each roll of product with the furnace batch, grade, tempering condition, diameter, batch number, and protect it with PE film and VCI anti-rust coating. Choosing the appropriate reel can reduce the number of line changes and ensure smooth feeding of the winding machine.
Typically, MOQ 200-500kg and small batch trial production can be conducted using stock spools. If you have any other needs, please feel free to contact us.
Main point is grade, Ni/Mo level, diameter, and tolerance, temper(soft/spring), surface and cleanliness(bright drawn, bright annealed, soap lubed, passivated), spool type, and coil weight. Definitely, tight tolerance, spring temper, bright annealed surface, and heavy spools are higher cost.
