1.2mm Diameter 304 Stainless Steel Spring Wire For Heavy Duty Applications

Bright/Soap-coated 200 / 300 /400 series Stainless Steel Spring Wire

Core Properties

304 Stainless Steel Spring Wire is a cold-drawn, austenitic alloy wire renowned for its excellent corrosion resistance, high tensile strength, and good fatigue life. Conforming to ASTM A313/ASTM A478, it is ideal for springs operating in corrosive or high-temperature environments up to 550°F (288°C).

Typical Uses Include

• Compression/Extension Springs in Marine Hardware

• Valve Springs for Chemical Equipment

• Medical Device Springs (ISO 13485 compliant)

• Food Industry Springs (FDA-compliant surfaces)

• Automotive Suspension Components

 Manufacturing Advantages)

Controlled Cold Drawing Process: Ensures uniform grain structure, consistent diameter tolerances (per ASTM E213), and enhanced surface finish (optional bright annealed). Available in diameters 0.01mm–12.0mm, with custom tempering options (e.g., 1/4 Hard to Full Hard).

Marketing Snippets

• Engineered Resilience: 304 SS spring wire – where precision meets corrosion defiance.

• From saline sprays to steam cycles: Trust 304 for springs that outlast.

• FDA-grade spring solutions for contamination-free performance.
