304 Stainless Steel Spring Wire 0.15–12mm for Precision Springs

Product Specification

TOPONE Wire supplies 304 stainless steel spring wire for precision spring manufacturing, wire forming, and industrial component production.

Made from AISI 304 / SUS304 stainless steel, this wire is available in diameters from 0.15mm to 12mm. Bright and soap-coated surface options are available according to processing requirements and application needs.

304 stainless steel spring wire can be used to manufacture compression springs, extension springs, torsion springs, retaining springs, and other formed-wire components. The appropriate wire diameter, tensile strength, and mechanical condition should be selected according to the spring design, forming process, and working environment.

For customized orders, buyers can specify the material grade, diameter, surface finish, mechanical properties, applicable standard, and packaging requirements.

Product Specifications

Note: Final mechanical properties, dimensional tolerances, and applicable standards should be confirmed before production.

Product Advantages

1. AISI 304 Stainless Steel

AISI 304 is an austenitic stainless steel grade commonly used for industrial wire and spring manufacturing. Its suitability depends on the required corrosion resistance, mechanical properties, and operating environment.

2. Wide Diameter Range: 0.15–12mm

The 0.15–12mm diameter range supports different spring designs and wire-forming requirements, from fine wire to larger industrial spring wire.

The required diameter and tolerance should be selected according to the spring geometry, working load, and production equipment.

3. Bright and Soap-Coated Surface Options

Bright wire provides a clean metallic surface, while soap-coated wire provides a lubricated surface condition that can be considered for suitable spring-coiling and cold-forming processes.

Surface selection should be based on tooling, lubrication requirements, and the intended manufacturing process.

4. Suitable for Different Spring Designs

Depending on the selected wire diameter and mechanical condition, 304 stainless steel spring wire can be used for compression springs, extension springs, torsion springs, retaining springs, and customized wire forms.

5. Customized Specifications

Buyers can specify wire diameter, surface finish, mechanical properties, packaging, and applicable standards according to their manufacturing requirements. Providing a technical drawing or detailed specification helps clarify the required wire properties.

Applications

Compression Springs

Used in selected mechanical assemblies and industrial equipment where the specified wire properties meet the spring design requirements.

Extension Springs

Suitable for extension spring production when wire diameter, tensile properties, and mechanical condition match the required load and working extension.

Torsion Springs

Can be considered for torsion spring manufacturing, with wire diameter, spring geometry, and mechanical properties evaluated together.

Precision Wire Forms

Can be processed into clips, hooks, retaining components, and other formed-wire parts according to the required design.

How to Select the Right 304 Stainless Steel Spring Wire

Before ordering, buyers should confirm the following:

• Material Grade: Specify AISI 304 / SUS304 or the required equivalent designation.

• Wire Diameter: Confirm the required diameter and dimensional tolerance.

• Tensile Strength: Provide the target range or applicable technical specification.

• Surface Finish: Select bright or soap-coated wire according to the forming process.

• Spring Type: Identify compression, extension, torsion, or other wire-forming requirements.

• Applicable Standard: Confirm the required material standard and inspection criteria.

• Packaging: Specify coil or spool requirements and preferred unit weight.

These details help establish a clear technical basis for product selection and quotation.

Quality Control for Precision Spring Wire

For precision spring applications, product quality should be evaluated using measurable specifications.

Relevant inspection items may include:

• Material grade and chemical composition

• Wire diameter and dimensional tolerance

• Surface condition

• Tensile strength and mechanical condition

• Coil dimensions and packaging

• Material traceability, where applicable

Inspection requirements should be agreed upon according to the customer's technical specification and applicable standard.
