Product Specification

0.6mm 302 Soap Coated Stainless Steel Spring Wire for Precision Spring Forming

Product Introduction

0.6mm 302 Soap Coated Stainless Steel Spring Wire is designed for precision spring manufacturing, wire forming and industrial components requiring a stainless steel spring wire with a soap-coated surface.

Made from AISI 302 / SUS302 stainless steel, this wire has a nominal diameter of 0.6mm, with an available diameter range of 0.15–12mm. The soap-coated surface is suitable for spring forming processes where the wire surface condition needs to match coiling equipment, tooling and downstream processing requirements.

AISI 302 is an austenitic stainless steel grade commonly used for spring wire and formed-wire applications. The final wire specification should be selected according to material grade, diameter, mechanical requirements, spring design, forming process and operating environment.

Product Specifications

Applications

Compression Springs

0.6mm 302 stainless steel spring wire can be used for manufacturing compression springs in mechanical equipment, industrial assemblies and other applications requiring fine spring wire.

The wire diameter, mechanical condition and spring geometry should be selected according to the required load, deflection and forming process.

Extension Springs

The wire can be formed into extension springs and other tension-loaded components.

For extension spring applications, wire diameter, spring dimensions, working load and operating conditions should be considered when selecting the appropriate specification.

Torsion Springs

302 soap coated stainless steel spring wire can also be used for torsion springs and other formed-wire components subjected to rotational loading.

The appropriate wire specification depends on the required torque, spring geometry, forming process and mechanical requirements.

Wire Forms and Small Components

The 0.6mm wire can also be processed into various formed-wire components, including:

• Clips

• Hooks

• Retaining components

• Fasteners

• Wire forms

• Small industrial components

Product Advantages

AISI 302 Stainless Steel

AISI 302 is an austenitic stainless steel grade commonly used for spring wire and formed-wire applications.

Its cold-working characteristics make it suitable for various spring forming and wire forming processes.

0.6mm Precision Wire

The nominal diameter of this product is 0.6mm, suitable for spring and wire-forming applications requiring a relatively fine wire specification.

The available diameter range of 0.15–12mm also provides options for different spring designs and production requirements.

Soap-Coated Surface

The soap-coated surface is designed for spring forming processes where surface condition needs to be considered together with coiling equipment, tooling and downstream processing.

The appropriate surface condition should be confirmed according to the customer's production process.

Flexible Application

302 stainless steel spring wire can be considered for compression springs, extension springs, torsion springs and various formed-wire components.

The final selection should be based on spring geometry, mechanical requirements, forming method and operating environment.

Coil or Spool Supply

The wire can be supplied in coils or spools according to wire diameter, production equipment, handling requirements and customer specifications.

Quality Control

For stainless steel spring wire, product quality should be evaluated through measurable technical parameters.

Depending on order requirements, inspection may include:

• Chemical composition verification

• Wire diameter measurement

• Surface inspection

• Tensile strength testing

• Dimensional inspection

• Coil or spool weight verification

• Material certificate

• Inspection report

For customized orders, buyers can specify the material grade, diameter, surface condition, tensile strength, applicable standard, quantity and packaging requirements.

How to Select 302 Soap Coated Spring Wire

1. Confirm the Material Grade

Specify AISI 302 / SUS302 or the required equivalent designation according to the applicable standard.

2. Confirm the Wire Diameter

The nominal diameter of this product is 0.6mm. Other sizes within 0.15–12mm can be selected according to the spring design and application.

3. Confirm Mechanical Requirements

Tensile strength and wire condition should be selected according to spring geometry, forming method, working load and operating requirements.

4. Confirm the Surface Condition

Soap coating can be considered when the wire surface needs to be compatible with spring coiling equipment, tooling and downstream processing.

5. Confirm the Applicable Standard

ASTM, JIS, EN, DIN, GB or equivalent specifications can be considered according to the customer's technical requirements.

Packaging and Supply

302 soap coated stainless steel spring wire can be supplied in coils or spools.

Packaging configuration can be selected according to wire diameter, coil weight, production equipment, handling requirements and transportation conditions.

For customized orders, packaging requirements should be confirmed together with the wire specification.
