316 Stainless Steel Spring Wire
We supply high-performance 316 stainless steel spring wire with wire diameters ranging from 0.2mm to 6.0mm. Stable smelting and drawing technology ensures uniform molybdenum distribution and consistent anti-corrosion performance of each 316 stainless steel spring wire.
Superior Corrosion Resistance
Outstanding anti-corrosion capacity
2%–3% molybdenum content delivers strong protection against chloride, sulfuric acid and phosphoric acid media.
Acid & alkali tolerance
Resists erosion of various acidic and alkaline solutions, ideal for chemical industry matching parts.
Excellent salt spray performance
Outperforms SUS304 obviously in coastal, marine and salt-containing environments to avoid pitting corrosion.
Optional low-carbon variant
316L low-carbon grade (carbon ≤0.03%) effectively prevents intergranular corrosion for welding and long-term high-temperature service.
Surface & Temper Options
Light drawn, half hard and full hard tempers are available; tensile strength ranges 1400MPa–2000MPa. Bright and matte surface finishes can be selected per customer demands.

Application Scope
Suitable for anti-corrosion springs, marine equipment accessories, medical devices and chemical fittings with strict anti-rust requirements.
