304 Stainless Steel Spring Wire
We provide full-spec 304 stainless steel spring wire with wire diameters from 0.1mm to 8.0mm. Consistent cold drawing and annealing processes stabilize mechanical parameters and surface smoothness for every 304 stainless steel spring wire.
Material Characteristics
Excellent rust resistance
Contains 18% chromium and 8% nickel, effectively resisting oxidation and corrosion in normal water and atmospheric environments.
Stable elastic performance
Uniform cold working and heat treatment fix elastic modulus, ensuring consistent rebound for finished springs.
Excellent moldability
Moderate plasticity supports coiling into compression, extension and torsion springs of all complex shapes.
Smooth surface
Bright and matte surface options are available without scratches or burrs to elevate finished product appearance.
Hardness & Strength Grade
Light drawn, half hard and full hard tempers are optional. Tensile strength ranges from 1500MPa to 2200MPa, adjustable based on wire diameter and processing state to match different spring production processes.
Application Scope
Widely used to fabricate stainless steel springs, hardware fasteners and wire mesh, covering hardware, electronics, machinery, medical devices and food processing equipment industries.
Complete Raw Material Quality Control System
Baoding Zhongxin Spring Manufacturing Co., Ltd. implements strict full-process inspection for 304 stainless steel spring wire. All raw steel coils are sourced from certified large steel mills with chemical composition and mechanical property sampling before production. Every production procedure has fixed process standards to lock dimensional tolerance, surface finish and tensile strength. Finished wire undergoes random sampling testing before delivery to fully meet national industry standards.
