Product Specification

2.2mm 302 Soap Coated Stainless Steel Spring Wire for Reliable Spring Forming

Product Introduction

2.2mm 302 Soap Coated Stainless Steel Spring Wire is designed for spring manufacturing, wire forming and industrial components requiring AISI 302 stainless steel with a soap-coated surface.

Made from AISI 302 / SUS302 stainless steel, this spring wire has a nominal diameter of 2.2mm, with an available diameter range of 0.15–12mm. The soap-coated surface can be selected for spring forming processes where wire surface condition needs to match coiling equipment, tooling and downstream processing.

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

Product Specifications

Applications

Compression Springs

2.2mm 302 stainless steel spring wire can be used for manufacturing compression springs for mechanical equipment, industrial assemblies and other spring applications.

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, the appropriate wire specification should be evaluated together with spring dimensions, working load, operating cycles and forming requirements.

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.

Wire diameter, spring geometry, torque requirements and forming conditions should be considered during material selection.

Wire Forms and Industrial Components

The wire can also be processed into various formed-wire products, including:

• Clips

• Hooks

• Retaining components

• Fasteners

• Wire forms

• Industrial formed-wire parts

Product Advantages

AISI 302 Stainless Steel

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

2.2mm Spring Wire

The nominal diameter of this product is 2.2mm, suitable for spring designs requiring this wire size.

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

Soap-Coated Surface

The soap-coated surface can be selected for spring forming processes where the wire surface needs to work with coiling equipment and tooling.

The suitable surface condition should be confirmed according to the customer's forming process and equipment.

Wide Application Range

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

The final specification should be determined 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 2.2mm. 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.
