Product Overview
Stainless steel wire is manufactured from premium stainless steel rod coils through precision multi-pass cold drawing, annealing and surface polishing processes. Featuring accurate dimensional tolerance, smooth burr-free surface and stable mechanical properties, our wires are available in three main tempers: soft wire (annealed), medium hard wire, and full hard spring wire. We cover the full series of 200, 300 and 400 grade stainless steel.
All products comply with GB, ASTM/AISI and JIS standards. Material test reports (MTR) and spectrum inspection certificates are available upon request. Widely applied in chemical industry, marine engineering, medical devices, mesh weaving, spring manufacturing, architectural decoration, precision hardware, welding and high-temperature resistant equipment.

| Grade | Description & Application |
|---|---|
| 201 Stainless Steel Wire | High manganese and low nickel composition with cost advantage and basic anti-rust ability. Suitable for indoor decoration, binding wire, common mesh and shelf accessories. Not recommended for outdoor or coastal environments. |
| 304 Stainless Steel Wire (Best Seller) | Classic 18-8 formula with balanced corrosion resistance, weldability and bending performance. Widely used in indoor hardware, kitchenware, filter mesh, architectural railing, common springs and woven mesh. |
| 304L Low Carbon Wire | Ultra-low carbon content effectively prevents intergranular corrosion after welding. Ideal for welded parts, large equipment welds and storage tank welding wire. |
| 304HC Copper Alloy Wire | Copper element improves cold forging performance, specially developed for screws, nuts and fastener processing, effectively avoiding cracking during stamping. |
| 302 Hard Wire | Higher carbon content provides excellent tensile strength, suitable for manufacturing springs, shrapnel, buckles and high-strength fasteners. |
| 316 / 316L Molybdenum Series Wire | Molybdenum element greatly improves resistance to chloride ion corrosion. Perfect for marine equipment, coastal hardware, chemical pipelines, medical devices and swimming pool facilities. 316L is more suitable for mass welding processing. |
