Product Specification

302 Stainless Steel Wire for Precision Applications

Product Introduction

302 Stainless Steel Wire is an austenitic stainless steel wire used in precision wire forming, spring manufacturing and industrial component production.

Manufactured from AISI 302 / SUS302 stainless steel, this wire can be considered for applications requiring stainless steel wire with suitable cold-working and forming characteristics. The appropriate specification depends on the component design, wire diameter, mechanical requirements, surface condition and operating environment.

Available diameters range from 0.15–12mm, with the specific size and surface finish selected according to customer requirements.

For precision applications, material grade, dimensional tolerances, tensile strength and applicable standards should be confirmed before production to ensure the wire meets the intended manufacturing requirements.

Product Specifications

Applications

Precision Wire Components

302 stainless steel wire can be considered for precision components that require a specified wire diameter, surface condition and mechanical properties.

The required dimensional tolerance and material condition should be defined according to the component drawing and production process.

Spring Manufacturing

AISI 302 stainless steel is commonly used for spring wire applications. The wire can be considered for compression springs, extension springs, torsion springs and other formed-wire components, depending on the specified mechanical condition.

Wire diameter, tensile strength, spring geometry and working load should be evaluated together during material selection.

Industrial Wire Forming

The wire can be processed into formed-wire components such as clips, hooks, retaining parts and other industrial components.

The appropriate material condition should be selected according to forming complexity, tooling requirements and the finished component's intended use.

Product Advantages

Austenitic Stainless Steel Material

AISI 302 is an austenitic stainless steel grade used in wire forming and spring manufacturing. Its suitability depends on the required mechanical properties, processing method and service environment.

Multiple Diameter Options

The available diameter range is 0.15–12mm, allowing buyers to specify wire sizes according to different component designs and manufacturing requirements.

Surface Options for Different Processes

Bright and soap-coated surfaces can be considered according to the application and production process. The final surface specification should be confirmed before ordering.

Specification-Based Manufacturing

For precision applications, buyers can specify the material grade, wire diameter, dimensional tolerance, tensile strength, surface finish and applicable standard.

These details provide a clearer basis for evaluating whether the wire meets the component's manufacturing requirements.

Quality Control and Inspection

Stainless steel wire for precision applications should be evaluated using measurable technical requirements.

Depending on the order specification, inspection may include:

• Chemical composition verification

• Wire diameter and dimensional tolerance measurement

• Surface condition inspection

• Tensile strength testing

• Material certificate review

• Coil or spool weight verification

• Inspection report preparation

Inspection items and acceptance criteria should be agreed upon before production.

How to Select Stainless Steel Wire for Precision Applications

1. Confirm the Material Grade

Specify AISI 302 / SUS302 or the exact material designation required by the engineering drawing.

2. Define the Diameter and Tolerance

Confirm the nominal wire diameter and permissible dimensional deviation. Precision applications may require tighter tolerances than general-purpose wire products.

3. Specify Mechanical Properties

Provide the required tensile strength, wire condition and forming requirements. These parameters should be confirmed against the intended application.

4. Select the Surface Finish

Choose the appropriate surface condition according to forming equipment, tooling, appearance and downstream processing requirements.

5. Confirm the Applicable Standard

Identify the relevant ASTM, JIS, EN, DIN or other material specification and confirm that the supplied wire meets the required grade and condition.

Packaging and Supply

Stainless steel wire can be supplied in coils or spools according to the confirmed product specification and customer requirements.

Packaging, coil weight and labeling should be agreed upon before production to support handling, identification and downstream processing.
