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

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

Available in diameters from 0.15mm to 12mm, this wire can be specified according to the requirements of different spring designs and manufacturing processes. Bright and soap-coated surface options can be considered according to tooling, lubrication, and forming requirements.

AISI 304 stainless steel is commonly used in industrial wire applications where corrosion resistance and mechanical properties are important. The appropriate wire specification depends on the required tensile strength, wire diameter, surface condition, and working environment.

For spring manufacturers, selecting the right wire involves more than choosing a material grade. Diameter tolerance, mechanical condition, surface finish, and forming requirements should also be considered to match the wire to the intended production process.

Product Specifications

Note: Confirm the actual material grade, manufacturing condition, dimensional tolerance, and applicable standard before ordering.

Product Advantages

1. AISI 304 Stainless Steel

AISI 304 is an austenitic stainless steel grade used in a wide range of industrial wire applications. Its suitability for spring manufacturing depends on the required mechanical properties, corrosion exposure, and operating conditions.

2. Wide Diameter Range from 0.15mm to 12mm

The 0.15–12mm diameter range covers different wire-processing and spring-manufacturing requirements. Selecting the appropriate diameter and dimensional tolerance is important for achieving the intended spring geometry and assembly fit.

3. Bright and Soap-Coated Surface Options

Bright wire provides a bright metallic surface, while soap-coated wire has a lubricating surface layer that may help reduce friction during suitable wire-forming operations.

The appropriate surface finish depends on the forming equipment, tooling, lubrication method, and finished-component requirements.

4. Specification-Based Mechanical Properties

Tensile strength and wire condition influence how spring wire behaves during forming and in the finished component. Buyers should define the required mechanical properties according to the spring design and manufacturing process.

5. Suitable for Different Spring Designs

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

Applications

Compression Spring Manufacturing

Suitable 304 stainless steel spring wire can be used to produce compression springs for mechanical assemblies and industrial equipment when the wire specifications match the design requirements.

Extension Spring Manufacturing

For extension springs, wire diameter, tensile strength, and mechanical condition should be selected according to the required load and working extension.

Torsion Spring Manufacturing

Torsion spring production requires consideration of wire diameter, spring geometry, material properties, and forming conditions.

Precision Wire Forming

304 stainless steel wire can be used for selected clips, hooks, retaining components, and other formed-wire parts, depending on the required geometry and mechanical properties.

How to Select 304 Stainless Steel Spring Wire

Before placing an order, buyers should confirm the following details:

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

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

• Tensile Strength: Provide the target range according to the spring design.

• Surface Finish: Choose 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.

• Order Quantity: Confirm the required quantity and delivery requirements.

Providing these details helps clarify the technical requirements and supports more accurate product selection.

Quality Inspection

For precision spring wire, quality evaluation should be based on measurable specifications rather than general descriptions.

Relevant inspection items may include:

• Material grade and chemical composition

• Wire diameter and dimensional tolerance

• Surface condition

• Tensile strength and mechanical condition

• Packaging and product identification

• Batch traceability, where applicable

The inspection methods and acceptance criteria should be agreed upon according to the customer's technical specification and applicable standards.

Frequently Asked Questions

What diameters are available for 304 stainless steel spring wire?

The specified diameter range is 0.15–12mm. The required size and tolerance should be confirmed before production.

What is the difference between bright and soap-coated spring wire?
