Product Specification

3mm 304 Stainless Steel Spring Wire for Spring Making

Product Introduction

304 Stainless Steel Spring Wire is designed for spring manufacturing and other applications requiring stainless steel wire with suitable mechanical properties for coiling and forming.

This product is supplied in a 3mm diameter, with stainless steel 304 material selected for applications where corrosion resistance, wire forming, and spring manufacturing requirements need to be considered together.

TOPONE Wire supplies stainless steel spring wire in 0.15–12mm diameters, with different surface conditions and supply specifications available according to the application.

For spring production, wire diameter, stainless steel grade, tensile strength, surface condition, spring design, and forming process should be confirmed according to the finished spring requirements.

Product Parameters

Material Characteristics

304 Stainless Steel

AISI 304 is an austenitic stainless steel grade widely used in stainless steel wire applications.

For spring manufacturing, 304 stainless steel can be selected when the application requires a combination of stainless steel properties, spring forming requirements, and resistance to the intended working environment.

The final material grade should be selected according to corrosion exposure, spring design, operating conditions, and required mechanical properties.

3mm Spring Wire

The standard specification for this product is 3mm diameter, suitable for spring-making applications where this wire size matches the spring design and forming equipment.

The actual spring performance depends on factors including wire diameter, material condition, spring geometry, coiling process, and required working load.

Applications

Spring Making

304 stainless steel spring wire can be used to manufacture various formed springs according to the required spring design and production process.

Applications may include:

• Compression springs

• Extension springs

• Torsion springs

• Formed wire springs

• Industrial springs

The appropriate wire specification should be determined according to spring dimensions, working load, operating environment, and forming equipment.

Industrial Components

Stainless steel spring wire can also be processed into formed wire components used in industrial equipment and mechanical assemblies.

Wire Forming

The wire can be processed through coiling, bending, and other forming operations according to the selected wire condition and spring design.

Product Advantages

304 Stainless Steel Material

304 stainless steel provides a widely used material option for spring and wire-forming applications where stainless steel properties are required.

3mm Diameter for Spring Production

The 3mm specification provides a defined wire size for spring manufacturers designing components around this diameter.

0.15–12mm Supply Range

TOPONE Wire supplies stainless steel spring wire across a 0.15–12mm diameter range, allowing customers to select different wire sizes according to spring design and production requirements.

Suitable for Different Spring Designs

The wire can be considered for compression, extension, torsion, and other formed spring designs, subject to the required material condition, diameter, spring geometry, and mechanical properties.

Customizable Supply

Customers can confirm requirements for material grade, diameter, surface condition, mechanical properties, coil weight, packaging, and applicable standard according to the spring production process.

How to Choose Stainless Steel Spring Wire

1. Confirm the Stainless Steel Grade

Select the appropriate grade according to corrosion exposure, operating environment, spring requirements, and applicable material specification.

2. Determine the Wire Diameter

The wire diameter should be selected according to spring dimensions, required load, coil diameter, spring geometry, and production equipment.

For this product, the specified diameter is 3mm, while other stainless steel spring wire sizes are available within the 0.15–12mm range.

3. Confirm Mechanical Properties

Spring manufacturers should confirm the required tensile strength, spring condition, and other mechanical requirements before production.

These properties should be evaluated together with the wire diameter and spring design rather than considered separately.

4. Select the Surface Condition

Bright or matte surface conditions can be selected according to the spring manufacturing process and final application.

5. Confirm the Applicable Standard

For technical purchasing, confirm the required ASTM, AISI, DIN, EN, JIS, or other applicable standard together with grade, diameter, mechanical properties, and surface requirements.

Spring Wire Selection Checklist

Before ordering 304 stainless steel spring wire, buyers should provide:

• Stainless steel grade

• Wire diameter

• Spring type

• Spring dimensions

• Required mechanical properties

• Surface condition

• Quantity

• Coil or spool requirements

• Applicable standard

• Application environment

Providing these details helps match the stainless steel spring wire with the customer's spring design and manufacturing process.

Technical Information

For B2B spring-wire purchasing, the product should be evaluated using measurable technical specifications.

Depending on the application, buyers can confirm:

• Stainless steel grade

• Wire diameter and tolerance

• Tensile strength

• Spring condition

• Surface condition

• Applicable standard

• Coil weight

• Packaging specification

• Inspection requirements

For customized spring wire requirements, the technical specification should be confirmed before production.
