Product Specification

304Cu S-Coated Stainless Steel Nail Wire for Cold Heading

Product Introduction

TOPONE Wire supplies 304Cu S-coated stainless steel nail wire for nail manufacturing, screw production, bolt forming and other cold-heading applications. Made from copper-containing austenitic stainless steel, this wire is designed for fastener production processes that require controlled material specifications and suitable surface lubrication.

The material specification includes 304Cu with a minimum copper content of 3%. The available wire diameter range is 0.15–12mm, allowing manufacturers to select dimensions according to the finished fastener design and forming equipment.

The wire features a soap-coated surface and skin-pass processing. These surface and processing conditions can be specified for selected cold-forming operations, depending on tooling, lubrication requirements and production methods.

For fastener manufacturers, material grade, copper content, wire diameter, tensile strength, dimensional tolerance and surface condition should be evaluated together to determine whether the wire meets the requirements of the intended production process.

Product Specifications

Exact tensile strength, elongation, dimensional tolerance and applicable material standard should be confirmed according to the selected diameter and customer requirements.

Product Advantages

1. 304Cu Material for Fastener Manufacturing

304Cu is a copper-containing austenitic stainless steel grade used in selected cold-heading and fastener manufacturing applications.

The specified minimum copper content of 3% provides a defined compositional requirement for material selection. Buyers should confirm the applicable material standard and chemical composition documentation when purchasing.

2. S-Coated Surface for Cold Forming

The soap-coated surface provides lubrication for selected wire-forming and cold-heading processes.

Surface lubrication can influence wire feeding, tooling contact and forming conditions. The suitable coating should be selected according to the forming equipment, die design, deformation requirements and subsequent processing steps.

3. Skin-Pass Surface Processing

Skin-pass processing is part of the specified surface preparation for this product. For applications with close dimensional or surface requirements, buyers should confirm the final diameter tolerance, surface condition and inspection criteria before production.

4. 0.15–12mm Diameter Range

The 0.15–12mm diameter range covers a broad selection of wire sizes for different nail and fastener designs.

The appropriate diameter depends on the finished component dimensions, forming allowance, tooling and production process. Nominal diameter and tolerance should be specified together.

5. Application-Specific Material Selection

Material grade, copper content, diameter, mechanical properties and surface condition can be specified according to the intended fastener application. Providing the finished-part drawing and forming requirements helps determine a suitable wire specification.

Applications

Stainless Steel Nail Manufacturing

304Cu S-coated wire can be used as raw material for stainless steel nail production when its material properties and mechanical condition meet the forming requirements.

Screw Manufacturing

The wire can be considered for screw production involving cold heading and subsequent threading or finishing operations. Diameter, mechanical condition and lubrication requirements should match the manufacturing process.

Bolt and Fastener Production

Suitable 304Cu wire specifications can be used for selected bolts, pins, studs and other cold-formed stainless steel fasteners.

Industrial Metal Components

The material can also be evaluated for other cold-formed components requiring a defined stainless steel grade and specified wire dimensions.

How to Select 304Cu S-Coated Nail Wire

1. Confirm the Material Grade

Specify SUS 304Cu and the required copper content according to the applicable material specification. Request relevant chemical composition documentation when necessary.

2. Select the Wire Diameter

Choose the nominal diameter within the 0.15–12mm range according to the finished nail, screw or fastener dimensions. Confirm the required dimensional tolerance before production.

3. Define Mechanical Properties

Specify the required tensile strength, elongation and mechanical condition based on the forming process and finished-part requirements. Do not assume one set of mechanical properties applies to every diameter.

4. Confirm the Surface Condition

Specify S-coated / soap-coated wire with skin-pass processing where required. Confirm compatibility with the production equipment, lubrication system and subsequent cleaning or finishing operations.

5. Provide Finished-Part Details

For accurate material selection, provide the fastener dimensions, forming method, tooling requirements, applicable standard, target mechanical properties and required coil weight.
