Product Specification

1.4mm 302 Soap Coated Stainless Steel Spring Wire for Smooth Spring Forming

Product Introduction

1.4mm 302 Soap Coated Stainless Steel Spring Wire is designed for spring manufacturing, wire forming and industrial components that require a stainless steel wire with a soap-coated surface.

Made from AISI 302 / SUS302 stainless steel, this spring wire has a nominal diameter of 1.4mm, with available sizes from 0.15–12mm. The soap-coated surface is suitable for applications where surface condition and forming performance need to match downstream coiling equipment and tooling.

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 conditions.

Product Specifications

Applications

Compression Springs

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

Wire diameter, tensile strength and spring geometry should be selected according to the required load, deflection and working conditions.

Extension Springs

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

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

Torsion Springs

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

The appropriate wire diameter and mechanical condition depend on the required torque, spring geometry and forming process.

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 wire-forming applications.

Its suitability for cold forming makes it a practical material option for various spring and formed-wire designs.

Soap-Coated Surface

The soap-coated surface is designed for spring forming processes where the wire surface needs to work with coiling equipment, tooling and downstream processing.

Surface condition should be selected according to the customer's forming equipment and production requirements.

0.15–12mm Diameter Range

The available diameter range is 0.15–12mm, covering fine stainless steel wire through larger spring wire specifications.

The nominal diameter of this product is 1.4mm.

Suitable for Different Spring Designs

The wire can be considered for compression, extension and torsion springs, as well as other formed-wire components.

The final specification should be determined based on spring dimensions, load requirements, forming method and operating environment.

Flexible Supply Forms

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

Quality Control

For stainless steel spring wire, product quality should be assessed 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, standard, quantity and packaging requirements.

How to Select Soap Coated 302 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 1.4mm. Other sizes within 0.15–12mm can be supplied according to the application and spring design.

3. Confirm Mechanical Requirements

Tensile strength and wire condition should be selected according to the spring design, forming process, working load and required operating conditions.

4. Confirm the Surface Condition

Soap coating can be selected when the wire surface needs to be compatible with the customer's spring forming equipment and tooling.

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.
