Product Specification

2.3mm 302 Stainless Steel Spring Wire for Reliable Spring Forming

Product Introduction

TOPONE supplies 302 stainless steel spring wire for compression, torsion, extension, and other formed spring applications.

This product features a 2.3mm wire diameter and is designed for spring manufacturers requiring stainless steel wire with a defined material grade and controlled dimensional specification.

The overall TOPONE stainless steel wire range covers 0.15–12mm, allowing different wire diameters to be selected according to spring dimensions, load requirements, forming processes, and installation conditions.

For customized spring projects, the required material grade, wire diameter, surface condition, mechanical requirements, and applicable standard should be confirmed before production.

Product Specifications

302 Stainless Steel Spring Wire

AISI 302 / SUS302 stainless steel is available for spring and wire-forming applications where a defined stainless steel material grade is required.

For spring production, material selection should be considered together with wire diameter, spring geometry, required load, working deflection, forming process, and operating environment.

The 2.3mm specification can be selected for spring designs requiring this wire diameter. The final specification should be confirmed based on the technical requirements of the finished spring.

0.15–12mm Wire Diameter Range

TOPONE provides stainless steel wire in a diameter range of 0.15–12mm.

This range covers different spring manufacturing requirements, from fine-wire components to larger industrial spring applications.

When selecting the wire diameter, buyers should consider:

• Spring outside diameter

• Spring inside diameter

• Mean coil diameter

• Free length

• Number of active coils

• Pitch

• Required load

• Working deflection

• Spring type

• Operating environment

Surface Options

Bright Surface

Bright stainless steel spring wire provides a clean metallic surface and can be selected where surface appearance and a defined wire surface condition are required.

Soap-Coated Surface

Soap-coated stainless steel wire provides a lubricated surface condition that can be suitable for certain wire-forming processes.

The appropriate surface should be selected according to the forming equipment, tooling, and production process.

Spring Applications

Compression Springs

302 stainless steel spring wire can be used for compression springs designed to resist compressive loads.

Wire diameter, coil diameter, free length, and number of active coils should be determined according to the spring design.

Torsion Springs

For torsion springs, the wire specification should be evaluated together with coil diameter, leg configuration, spring geometry, and required operating torque.

Extension Springs

302 stainless steel spring wire can also be formed into extension springs with customized coil dimensions and end configurations.

Industrial Spring Components

The wire can be used for customized spring components in mechanical assemblies, industrial equipment, and other applications requiring stainless steel spring wire.

Spring Wire Selection Guide

Material Grade

Confirm whether 302 stainless steel meets the required material characteristics and applicable standard for the spring application.

Wire Diameter

The required wire diameter should be selected according to spring dimensions, load, deflection, and available installation space.

The featured diameter is 2.3mm, while the overall available range is 0.15–12mm.

Spring Type

Identify whether the application requires a compression spring, torsion spring, extension spring, or another spring configuration.

Surface Condition

Select bright or soap-coated surface according to the forming equipment and production requirements.

Working Environment

Consider temperature, moisture, chemical exposure, load, movement, and installation conditions when selecting the spring wire specification.

Quality and Specification Control

For stainless steel spring wire, the final product should be evaluated against clearly defined technical specifications.

Important specification and inspection items may include:

• Stainless steel grade

• Chemical composition

• Wire diameter

• Diameter tolerance

• Surface condition

• Tensile strength

• Temper condition

• Applicable standard

• Coil or spool weight

• Packaging condition

Mechanical requirements should be confirmed according to the selected wire diameter, temper, and applicable standard rather than applying one fixed value to all spring wire sizes.
