• Uniform Material Structure & Purity: Adopts high-purity stainless steel billets with low sulfur and phosphorus content (≤0.03%), ensuring a uniform austenitic/ferritic structure. The wire undergoes vacuum melting and refining to remove impurities, further enhancing corrosion resistance and mechanical properties. All materials comply with EU EN 10088, US ASTM A498, and ISO 6892 standards 25.
• Passivation Treatment for Enhanced Protection: All stainless steel wires undergo professional passivation treatment (using nitric acid or citric acid solution), forming a dense oxide film on the surface. This film significantly improves corrosion resistance, making the wire withstand 2000+ hours of salt spray corrosion (ASTM B117 standard) for 304 grade and 3000+ hours for 316 grade 46.

✅ High Tensile Strength & Mechanical Stability

• Precision Drawing & Heat Treatment: The stainless steel billets undergo 6-10 passes of precision diamond die drawing, achieving precise diameter (error ≤±0.01mm) and smooth surface. According to application needs, we provide different strength grades: soft (annealed), half-hard, and full-hard. The soft wire has excellent ductility for easy shaping; the full-hard wire has high tensile strength (≥1200MPa for 304 grade) for heavy-duty reinforcement scenarios47.
• Stable Performance in Extreme Conditions: The stainless steel wire maintains stable mechanical properties in extreme temperatures (-270℃ to 1200℃, depending on grade), avoiding brittle fracture in cold regions (Northern Europe, Canada) and softening in high-temperature environments (Middle East, Africa). It also has excellent fatigue resistance, withstanding repeated bending and tension without deformation 69.
• Consistent Quality Batch-to-Batch: Advanced production lines and strict quality control ensure uniform diameter, strength, and surface quality across batches. This consistency is critical for mass production industries such as electronics, automotive, and food processing 38.

✅ Hygienic & Environmentally Friendly & Versatile Specifications

• Hygienic & Easy to Clean: The smooth surface of stainless steel wire has no pores or cracks, preventing the growth of bacteria and microorganisms. It is non-toxic, tasteless, and complies with EU FDA and US NSF food safety standards, making it ideal for food processing, medical equipment, and pharmaceutical applications 79.
• Environmentally Friendly & Recyclable: Stainless steel is 100% recyclable, with no environmental pollution during production and use. Our production processes adopt environmentally friendly technologies, complying with EU RoHS and US EPA standards, meeting global green development requirements 35.

🏭 Core Manufacturing Process & Professional Surface Treatment

1. Core Manufacturing Processes: Precision Control from Melting to Drawing

• Vacuum Melting & High-Purity Billet Preparation: We adopt vacuum induction melting technology for high-purity stainless steel raw materials (chromium, nickel, iron, etc.). This process effectively avoids oxidation and impurity contamination during melting, ensuring the chemical composition of the molten steel is uniform and stable. The molten steel is then cast into billets through precision casting, and the billets are hot-rolled into wire rods with uniform diameter (error ≤±0.1mm) and dense internal structure, laying a solid foundation for subsequent drawing processing 47.
• Multi-Pass Precision Cold Drawing & Intermediate Annealing: The hot-rolled wire rods are subjected to multi-pass cold drawing using diamond dies (6-10 passes according to diameter requirements). Each pass of drawing is controlled by an intelligent computer system to ensure the wire diameter accuracy reaches ≤±0.01mm and the surface is smooth without burrs. Between drawing passes, intermediate annealing treatment is performed (1050-1150℃ for austenitic stainless steel such as 304/316L) in a protective atmosphere. This step eliminates internal stress generated during drawing, improves the ductility of the wire, and adjusts the mechanical properties to meet different strength requirements (soft, half-hard, full-hard) 26.
• Precision Cutting & Finishing Calibration: After drawing, the wire is cut into fixed-length straight wires (50mm-2000mm, length error ≤±0.1mm) by automatic precision cutting equipment or coiled into coils (1kg-50kg/coil) by an intelligent coiling machine. For high-precision application scenarios, additional finishing calibration is performed to ensure the straightness of the wire (straightness error ≤0.5mm/m) and the uniformity of the coil tension 68.

2. Professional Surface Treatment: Enhancing Corrosion Resistance & Aesthetics

3. Strict Quality Control for Manufacturing & Surface Treatment

• In-Process Inspection for Manufacturing: During the melting process, real-time monitoring of the chemical composition of molten steel is performed using a spectrometer; during drawing, the wire diameter is inspected every 30 minutes using a micrometer; the annealing temperature and time are strictly recorded and controlled to ensure consistent mechanical properties of the wire 68.
• Pickling & Derusting: Cleaning Surface Oxide Scale: The drawn wire first undergoes pickling treatment using a mixed acid solution (nitric acid + hydrofluoric acid) that is environmentally friendly and meets EU RoHS standards. This process effectively removes oxide scale, rust, and oil stains on the wire surface, ensuring the subsequent surface treatment effect. After pickling, the wire is rinsed with high-purity water multiple times to avoid acid residue 58.
• Passivation Treatment: Forming Protective Oxide Film: All stainless steel wires are subjected to professional passivation treatment, using either nitric acid or citric acid solution (selectable according to customer needs). Under controlled temperature and time conditions, a dense, uniform, and firmly bonded oxide film is formed on the wire surface. This film significantly enhances the corrosion resistance of the wire, enabling 304 grade to withstand 2000+ hours of salt spray corrosion (ASTM B117 standard) and 316L grade to withstand 3000+ hours 46.
• Optional Surface Finishing: Meeting Diverse Aesthetic & Precision Needs: According to application scenarios, we provide three surface finish options: ① Bright Finish: Achieved by polishing with a precision polishing wheel, the surface is bright and reflective, suitable for architectural decoration and handicrafts; ② Matte Finish: Obtained by sandblasting or chemical matting, the surface is smooth without glare, suitable for food processing equipment; ③ Precision Polishing: For high-precision scenarios such as medical equipment, the surface roughness Ra ≤0.2μm, ensuring hygiene and easy cleaning 27.
• Drying & Anti-Rust Protection: After surface treatment, the wire is dried in a constant-temperature oven (120-150℃) to ensure surface dryness. For coil products, a thin layer of food-grade anti-rust oil (optional) is applied to further protect the surface during storage and transportation 89.
• Surface Quality & Performance Testing: After surface treatment, the wire surface is inspected for defects such as scratches, pits, and uneven passivation film using a magnifying glass and a surface roughness tester. Corrosion resistance testing (salt spray test, ASTM B117) is performed on finished products to ensure the passivation effect. A 1% random sampling method is adopted for each batch, and only products that pass all tests are allowed to leave the factory 9.
