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).
