Product Introduction

2.2mm 302 Soap-Coated Stainless Steel Spring Wire is a cold-drawn stainless steel wire designed for spring manufacturing, wire forming and industrial components.

Manufactured from AISI 302 stainless steel, this spring wire features a soap-coated surface suitable for different spring coiling and wire-forming processes. The nominal diameter of this product is 2.2mm, with a diameter range of 0.15–12mm available for customized requirements.

AISI 302 is an austenitic stainless steel grade commonly used for stainless steel spring wire applications. Through cold drawing, the wire diameter and mechanical condition can be controlled to meet different spring manufacturing requirements.

For spring applications, material grade, wire diameter, surface condition, tensile strength and forming process should be selected according to the final component design and working conditions.

Product Specifications

AISI 302 Stainless Steel Spring Wire

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

The material is selected for applications requiring stainless steel characteristics combined with cold-worked mechanical properties.

For 302 spring wire selection, buyers should confirm:

• Stainless Steel Grade
• Wire Diameter
• Surface Condition
• Tensile Strength Requirement
• Spring Design
• Applicable Standard

These parameters help ensure the wire specification matches the customer's forming equipment and application requirements.

2.2mm Stainless Steel Spring Wire

The nominal diameter of this product is 2.2mm.

Compared with fine wire sizes, 2.2mm stainless steel spring wire is suitable for applications requiring a larger wire diameter and higher structural support.

When selecting 2.2mm spring wire, manufacturers should consider:

• Spring Outer Diameter
• Coil Diameter
• Number of Active Coils
• Working Load
• Deflection Requirement
• Operating Environment

The final wire condition should be confirmed according to the spring drawing and production requirements.

Soap-Coated Surface

The soap-coated surface provides a suitable surface condition for spring manufacturing and wire forming processes.

Surface selection should be based on:

• Automatic coiling equipment
• Tooling requirements
• Forming process
• Final component requirements

For applications requiring a bright metallic appearance, bright surface options can also be provided according to customer requirements.

Diameter Range: 0.15–12mm

TOPONE supplies stainless steel spring wire with diameters from 0.15mm to 12mm.

The size range covers:

• Fine Precision Spring Wire
• Industrial Spring Wire
• Wire Forming Wire

Compression Springs

2.2mm 302 stainless steel spring wire can be used for compression spring manufacturing where the wire specification matches the required spring design.

Common applications include:

• Industrial Equipment
• Mechanical Components
• Hardware Assemblies
• Stainless Steel Spring Parts

Extension Springs

The wire can be processed into extension springs used in mechanical assemblies.

The appropriate wire specification should be selected according to:

• Required Load
• Spring Dimensions
• Working Conditions
• Forming Process

Torsion Springs

302 stainless steel spring wire can also be used for torsion spring applications.

For torsion spring production, wire diameter, spring geometry and required torque should be considered together.

Wire Forms and Fasteners

The wire can also be processed into:

• Clips
• Hooks
• Retaining Rings
• Wire Forms
• Fasteners
• Hardware Components
