Product Specification

AISI 302 Stainless Steel Spring Wire 0.15–12mm for Fencing Applications

Product Introduction

AISI 302 stainless steel spring wire is an austenitic stainless steel wire commonly selected for spring and formed-wire applications where mechanical performance and corrosion resistance are required.

TOPONE supplies AISI 302 stainless steel spring wire in diameters from 0.15 to 12 mm. The wire can be produced through controlled cold drawing and heat treatment processes according to the required material condition, diameter, mechanical properties, and application.

For fencing systems and other outdoor wire components, material selection should consider the required wire diameter, spring performance, corrosion environment, forming process, and service conditions.

The actual tensile strength and mechanical condition should be confirmed according to the specified diameter, production condition, and applicable standard.

Product Specifications

Specific tensile strength, elongation, dimensional tolerance and surface condition should be confirmed according to material grade, diameter, standard and application.

AISI 302 Stainless Steel Spring Wire

AISI 302 stainless steel is an austenitic stainless steel grade widely used for wire and spring applications.

When processed into spring wire, the material condition can be adjusted through cold drawing and appropriate heat-treatment procedures according to the required mechanical properties.

For spring manufacturing, the wire specification should not be selected by material grade alone. Diameter, tensile condition, spring geometry, forming method and working environment should also be considered.

Cold Drawing and Heat Treatment

Cold Drawing

Cold drawing is used to reduce the wire diameter and control the dimensional condition of stainless steel wire.

For spring-wire applications, the drawing condition is closely related to the required mechanical properties and subsequent forming process.

Heat Treatment

Heat treatment can be used as part of the production process to obtain the required material condition for specific applications.

The appropriate process depends on the stainless steel grade, wire diameter, target mechanical properties and applicable production specification.

For this reason, the final mechanical condition should be confirmed against the buyer's technical requirements rather than assumed solely from the material grade.

Applications

AISI 302 stainless steel spring wire can be considered for applications including:

• Stainless steel fencing components

• Spring-loaded fencing parts

• Compression springs

• Torsion springs

• Extension springs

• Wire clips

• Retaining components

• Formed-wire components

• Industrial springs

• Custom spring components

For fencing applications, the selection should take into account outdoor exposure, required spring force, forming geometry, wire diameter and expected service conditions.

Product Advantages

0.15–12 mm Diameter Range

The available diameter range of 0.15–12 mm covers fine stainless steel spring wire as well as larger-diameter wire requirements.

AISI 302 Material

AISI 302 provides an established stainless steel option for spring and formed-wire applications where a combination of corrosion resistance and mechanical performance is required.

Controlled Drawing Process

Cold drawing allows the wire diameter and material condition to be controlled according to the required specification.

Application-Oriented Material Selection

The wire can be specified according to diameter, mechanical condition, surface requirement, forming process and application rather than relying only on the stainless steel grade.

Suitable for Fencing and Spring Components

AISI 302 spring wire can be used for fencing-related spring components and various industrial formed-wire applications when the wire condition is matched to the required forming and service conditions.

How to Select Stainless Steel Spring Wire

Before selecting AISI 302 spring wire, buyers should confirm the following parameters:

1. Wire diameter: 0.15–12 mm

2. Material grade: AISI 302 / SUS 302

3. Required tensile strength or mechanical condition

4. Spring type: compression, torsion, extension or custom spring

5. Surface requirement: bright, matte or other specified condition

6. Forming method: automatic coiling, CNC forming or other forming process

7. Working environment: indoor, outdoor, moisture or corrosive conditions

8. Applicable standard: ASTM, AISI, JIS, EN or customer specification

9. Required dimensional tolerance

10. Packaging requirement: coil, spool or customized packaging

These parameters help determine whether the selected wire condition is suitable for the actual spring-forming process.

Stainless Steel Spring Wire vs. General Stainless Steel Wire

Stainless steel wire should not be classified as spring wire simply because it is made from stainless steel.

Spring applications normally require a specific combination of material grade, diameter, mechanical condition and forming requirements.

For example, the same stainless steel grade may be supplied in different material conditions for different applications. Therefore, buyers should specify the intended application and mechanical requirements when requesting stainless steel spring wire.
