304 Stainless Steel Spring Steel Wire Key benefits Reliable corrosion resistance: Made from 304 stainless steel to resist rust and extend service life in humid or exposed environments. Consistent spring performance: Engineered for good elasticity so coils, clips, and wire forms retain shape and function under repeated load. Wide size range for precision work: Available in diameters from 0.4 mm to 2.0 mm to match small and medium spring and wire-forming needs. What this product does for you Solves premature failure from rust or loss of spring force by combining stainless corrosion protection with elastic spring properties. Provides a readily formable wire that holds dimensions after winding or bending, reducing rework and improving part reliability. Fits applications that require durable, corrosion-resistant spring wire without changing material or process. Key specifications Name: 304 stainless steel spring steel wire Material: 304 stainless steel Diameter range: 0.4 mm to 2.0 mm Main attributes: corrosion resistant, not easy to rust, good elasticity Practical applications (examples) Small compression and extension springs for consumer products, mechanical assemblies, and prototypes where rust resistance is needed. Clips, retainers, and wire forms used in automotive trim, appliances, or fixtures that require repeated flexing and exposure to moisture. Hobby, model-making, and DIY projects where precise diameters and reliable springiness are required for repeatable results. Compatibility and handling Suitable for spring coiling, manual forming, bending, and basic wire-forming tools. Confirm tooling tolerances for the chosen diameter. Available diameters (0.4–2.0 mm) cover many common spring and wire-form applications; choose the diameter that matches your design load and space constraints. Performance notes The 304 stainless base offers strong corrosion resistance and long-term dimensional stability in typical environments. Good elasticity supports repeated use; final performance depends on coil design, heat treatment, and working limits applied during forming. Order guidance Select the diameter that best fits your spring rate, load, and space needs within the 0.4 mm to 2.0 mm range. If you require specific lengths or forms, specify diameter and required length or drawing when ordering to ensure compatibility.
