304 Stainless Steel Spring Steel Wire (Diameter 0.4 mm – 2.0 mm) Key benefits Durable and corrosion resistant: Made from 304 stainless steel for long service life in humid or mildly corrosive environments. Reliable spring performance: Good elasticity and shape recovery make it suitable for small springs, clips, and retaining components. Versatile sizing: Available in diameters from 0.4 mm to 2.0 mm to fit a wide range of projects and assemblies. What this product solves Eliminates premature failure from rust or surface corrosion common with low-grade steel. Provides consistent elastic response for small mechanical parts where repeatable deflection and return are required. Simplifies material choice when a balance of formability, corrosion resistance, and spring behavior is needed. Specifications Name: 304 stainless steel spring steel wire Material: 304 stainless steel Available sizes: diameter 0.4 mm – 2.0 mm Key attributes: corrosion resistant, resists rust, good elasticity Performance and compatibility Suitable for forming into small springs, clips, pins, and bent parts; compatible with standard wire-working tools (bending, coiling, cutting) used for 0.4–2.0 mm wire. 304 stainless provides good formability and moderate strength; ideal where corrosion resistance is a priority and extremely high spring forces are not required. Can be finished or coated if additional surface protection or appearance is needed. Typical applications Small compression and extension springs for appliances, instruments, and consumer products. Wire clips, retaining rings, connectors, and fasteners used in electronics, automotive interiors, and mechanical assemblies. Hobby, model-making, and jewelry projects where corrosion resistance and reliable spring action are required. Usage tips Choose the appropriate diameter within the 0.4–2.0 mm range based on required load and space constraints; thicker wire increases stiffness. Use proper wire-forming tools and annealing if extensive bending is required to reduce cracking. Store in a dry environment to preserve surface condition, though 304 stainless is resistant to rust under normal conditions. Ordering note Confirm the required diameter to match your design specifications; contact your supplier for available lengths and packaging options.
