Product Specification

302 Stainless Steel Spring Wire 0.15–12mm for Industrial Springs

Product Introduction

TOPONE Wire supplies 302 stainless steel spring wire in diameters from 0.15 to 12 mm for industrial springs, wire-formed components and applications requiring stainless steel spring wire with defined mechanical properties.

AISI 302 stainless steel is commonly used for spring applications because its mechanical condition can be adjusted through cold working and wire drawing. The final wire condition, diameter and mechanical properties should be selected according to the spring design, forming process and service requirements.

For precision spring manufacturing, important purchasing parameters include wire diameter, dimensional tolerance, tensile strength, surface condition, material grade and applicable standard. These specifications should be confirmed according to the actual spring design rather than relying on the material grade alone.

TOPONE Wire can supply 302 stainless steel spring wire in different diameters and technical conditions according to production requirements.

Product Specifications

Technical note: Tensile strength, dimensional tolerance and other mechanical properties vary according to wire diameter, cold-working condition and applicable specification. Final values should be confirmed against the production specification or inspection document.

Why Choose 302 Stainless Steel Spring Wire?

302 stainless steel is a chromium-nickel stainless steel grade commonly used for cold-worked wire and spring applications.

Its suitability for spring manufacturing depends on the supplied mechanical condition and the requirements of the finished component. For industrial spring production, the material should therefore be evaluated together with wire diameter, tensile strength, spring geometry, forming process and working environment.

This makes 302 stainless steel spring wire suitable for manufacturers looking for a stainless steel material for applications involving repeated spring action and wire forming.

Diameter Range: 0.15–12mm

TOPONE Wire supplies 302 stainless steel spring wire from 0.15 to 12 mm.

The required wire diameter should be selected according to the spring design and manufacturing process.

These diameter groups are application references rather than fixed limitations. The final diameter should be determined according to spring dimensions, load requirements, working deflection and forming equipment.

Applications

302 stainless steel spring wire can be used for a variety of industrial and mechanical components, including:

• Compression springs

• Extension springs

• Torsion springs

• Coil springs

• Wire forms

• Retaining clips

• Industrial spring components

• Mechanical fastening components

• Electrical components

• Precision wire-formed parts

• Customized stainless steel springs

• General industrial hardware

For applications involving corrosive environments, the material grade should be evaluated together with the actual operating conditions, including moisture, chlorides, chemicals and temperature.

Spring Wire Selection Guide

1. Confirm the Spring Type

Compression, extension and torsion springs have different geometries and loading conditions. The wire specification should therefore be selected according to the finished spring design.

2. Select the Wire Diameter

Wire diameter affects the geometry and mechanical behavior of the finished spring. TOPONE Wire supplies 0.15–12 mm302 stainless steel spring wire.

3. Confirm Mechanical Properties

For spring applications, tensile strength and mechanical condition are important purchasing parameters. The required values should be specified according to the spring design and manufacturing process.

4. Check Dimensional Tolerance

Precision spring production may require controlled wire diameter and dimensional tolerance. Buyers should provide the required tolerance when requesting a technical quotation.

5. Confirm Surface Condition

Surface condition should be selected according to the forming process, appearance requirements and subsequent manufacturing operations.

Product Advantages

302 Stainless Steel Grade

302 stainless steel provides a commonly used material option for stainless steel spring wire and cold-worked wire applications.

0.15–12mm Diameter Range

The diameter range covers fine spring wire through larger industrial spring-wire requirements.

Suitable for Cold-Worked Spring Applications

The mechanical condition of spring wire is related to the amount of cold working and the final production specification. This allows the wire condition to be matched with the required spring performance.

Suitable for Precision Spring Manufacturing

For precision applications, buyers can specify diameter, tolerance, mechanical properties, surface condition and applicable standards according to the spring design.

Application-Based Customization

Grade, diameter, tolerance, mechanical condition, surface requirement and packaging can be discussed according to the customer's production requirements.

Quality and Technical Information

For B2B spring-wire purchasing, product quality should be evaluated through measurable technical specifications.

Depending on the project, the product specification can include:

• Stainless steel grade

• Chemical composition

• Wire diameter

• Diameter tolerance

• Tensile strength

• Mechanical condition

• Surface condition

• Applicable standard

• Inspection requirements

• Packaging specification

Where required, material and inspection documentation can be discussed before production.

302 Stainless Steel Spring Wire vs. 304 Spring Wire

Both 302 and 304 are chromium-nickel stainless steel grades used in wire applications, but material selection should be based on the specific product specification and service requirements.

For spring manufacturers, the more important comparison may include:

The appropriate grade should be confirmed according to the required mechanical properties, corrosion environment, manufacturing process and applicable standard.
