302 Soap-Coated Stainless Steel Spring Wire | Low Friction

302 Soap-Coated Stainless Steel Spring Wire

TOPONE 302 Soap-Coated Stainless Steel Spring Wire is an AISI 302 austenitic stainless steel wire designed for spring manufacturing, wire forming and other applications requiring controlled wire diameter and suitable mechanical properties.

The wire is available in 0.15–12mm diameter and can be supplied with a soap-coated or bright surface according to the forming process and end-use requirements. Coil and spool packaging are available for different production lines.

For buyers specifying stainless steel spring wire, the appropriate diameter, temper, tensile strength and surface condition should be selected according to the spring design and forming equipment rather than using one specification for all applications.

Product Specifications

Note: Mechanical properties, dimensional tolerance and surface requirements should be confirmed according to the specified diameter, temper and applicable standard. Inspection documents can be provided according to order requirements.

Why Choose Soap-Coated 302 Stainless Steel Wire?

1. Soap-Coated Surface for Wire Forming

The soap-coated surface is suitable for manufacturing processes where controlled wire feeding and forming are required. Surface selection can be discussed according to the customer's coiling, forming and subsequent processing equipment.

For applications requiring a cleaner or more visible metallic surface, a bright finish can also be supplied.

2. AISI 302 Stainless Steel Material

AISI 302 is an austenitic chromium-nickel stainless steel grade commonly used in wire and spring applications. Its material composition provides a combination of corrosion resistance, ductility and cold-working capability.

The actual mechanical performance depends on wire diameter, cold reduction, temper and specified standard, so these parameters should be considered together when selecting spring wire.

3. 0.15–12mm Diameter Range

TOPONE supplies 302 stainless steel wire in diameters from 0.15mm to 12mm, covering fine wire and larger-diameter wire requirements.

Different diameters can be matched with different spring designs, wire-forming processes and equipment requirements. For customized orders, buyers can provide the required diameter, tolerance, surface and quantity for specification confirmation.

4. Coil and Spool Supply

The wire can be supplied in coil or spool form. Packaging can be selected according to wire diameter, coil weight, transportation requirements and the customer's production equipment.

For automated wire forming and spring production, packaging and unwinding requirements should be confirmed before production.

Typical Applications

Spring Manufacturing

302 stainless steel spring wire can be used for the production of various stainless steel spring components, including:

• Compression springs

• Extension springs

• Torsion springs

• Small industrial springs

• Custom spring components

The required wire diameter and temper should be selected according to spring load, dimensions, forming method and working conditions.

Wire Forming

The wire can also be used for forming applications where stainless steel wire is bent, coiled or shaped into finished components.

Typical products include:

• Wire forms

• Clips

• Retaining components

• Fasteners

• Hardware components

Industrial and General Hardware

302 stainless steel wire is also applicable to selected industrial hardware and components where stainless steel material and controlled wire dimensions are required.

How to Select 302 Stainless Steel Spring Wire

When requesting a quotation or technical confirmation, buyers should provide the following information:

1. Grade: AISI 302 or required equivalent

2. Diameter: Required wire diameter within 0.15–12mm

3. Tolerance: Required dimensional tolerance

4. Surface: Soap coated or bright

5. Temper: Hard or soft annealed, according to application

6. Application: Spring, wire forming, clip, hardware or other use

7. Quantity: Required weight or coil quantity

8. Packaging: Coil, spool or customized packaging

9. Standard: Required ASTM, EN, DIN, JIS, GB or other applicable standard

Providing these parameters allows the material, mechanical properties and production condition to be evaluated against the actual application.

Quality and Documentation

For B2B industrial orders, product specifications should be confirmed before production. Depending on the order requirements, documentation may include material certificates, inspection reports and applicable quality documentation.

TOPONE can discuss material grade, diameter, surface condition, packaging and inspection requirements with buyers before production.

FAQ

What is 302 soap-coated stainless steel wire used for?

It is mainly used for spring manufacturing, wire forming and selected hardware applications where AISI 302 stainless steel wire is required.

What diameter range is available?

The standard product range is 0.15–12mm. Specific diameter tolerance should be confirmed according to the required size and applicable specification.

What is the difference between soap-coated and bright stainless steel wire?

Soap-coated wire has a surface treatment intended to support wire processing and forming, while bright wire provides a cleaner metallic surface. The suitable finish depends on the forming process and final application.

Can the wire be supplied on spools?

Yes. Coil and spool packaging can be discussed according to wire diameter, weight and production equipment.

What information should I provide for a quotation?

Please provide the grade, diameter, tolerance, surface, temper, quantity and application. Packaging requirements can also be specified if needed.
