0.8mm SUS 304Cu Stainless Steel Cold Heading Wire with Bright Surface

0.8mm SUS 304Cu Stainless Steel Cold Heading Wire is designed for cold heading and cold forming applications where stainless steel wire is shaped into fasteners and precision metal components.

This product has a nominal diameter of 0.8mm, SUS 304Cu material, bright surface, and a coil inner diameter range of 250–1000mm.

ASTM A493 covers stainless steel wire and wire rod intended for cold heading and cold forging, including requirements related to chemical composition and mechanical properties.

ISO 4954-2:2024 also specifies technical delivery conditions for stainless steels intended for cold heading and cold extruding, including austenitic stainless steel sizes starting from 0.8mm.

Product Specifications

Key Features

Designed for Cold Heading

This stainless steel wire is positioned for cold heading and cold forming applications. The wire material, diameter, supply condition and mechanical properties should be matched with the forming process and final component design.

0.8mm Fine Diameter

The 0.8mm diameter is suitable for small fasteners and precision metal components requiring fine-gauge wire. For production applications, diameter tolerance and mechanical properties should be confirmed according to the forming equipment and tooling requirements.

Bright Surface

The bright surface provides a clean surface condition for applications where wire appearance and surface condition are part of the material selection criteria.

Flexible Coil Configuration

The listed coil inner diameter is 250–1000mm. The appropriate coil configuration can be selected according to the customer's decoiling and feeding equipment.

Applications

Fasteners

304Cu stainless steel cold heading wire can be used for manufacturing cold-formed fasteners such as:

• Screws

• Bolts

• Rivets

• Pins

• Studs

• Small precision fasteners

ASTM A493 specifically covers stainless steel wire and wire rod for cold heading and cold forging applications, including fastener production.

Precision Metal Components

The 0.8mm wire diameter can be considered for small metal components and precision parts produced through cold forming. Final suitability should be evaluated according to component geometry, deformation requirements and required mechanical properties.

Cold Forming

The product can be considered for cold heading, cold forging and related cold forming processes where stainless steel wire is used as the starting material.

Product Advantages

Defined Material Grade

SUS 304Cu provides a clearly specified stainless steel material grade for applications requiring stainless steel wire for cold forming.

Fine Wire Diameter

The 0.8mm nominal diameter makes the wire suitable for fine-gauge cold forming applications. Actual dimensional tolerance should be confirmed according to the applicable standard and production requirements.

Bright Surface

The bright surface condition is suitable for applications where wire surface appearance and condition are important during material selection.

Multiple Standards

The product page lists JIS, EN, ASTM, DIN and GB standards. The applicable standard should be confirmed according to the customer's technical specification and order requirements.

What Should Buyers Confirm Before Ordering?

For stainless steel cold heading wire, buyers should provide the following information:

1. Stainless steel grade

2. Wire diameter

3. Surface condition

4. Cold heading or cold forging process

5. Final component type

6. Required mechanical properties

7. Applicable material standard

8. Coil inner diameter

9. Packaging requirements

10. Quantity and delivery configuration

Providing these parameters allows the wire specification to be evaluated against the actual forming process instead of selecting material only by the broad keyword “304 stainless steel wire.”

Quality & Technical Documentation

For B2B engineering and purchasing evaluation, the product page can be supported with technical documentation such as:

• Material Test Certificate / MTC

• Chemical Composition

• Mechanical Properties

• Diameter Tolerance

• Surface Condition

• Coil Weight

• Coil Inner Diameter

• Applicable Standard

• Inspection Method

• Packing Specification

These technical details can provide stronger E-E-A-T signals and help engineers and purchasing teams evaluate the material for a specific manufacturing process.

Packaging

The wire can be supplied in coil packaging or special packing with a plate. The final packaging configuration can be confirmed according to coil dimensions, transportation requirements and customer handling equipment.

Technical Inquiry

For cold heading, cold forging or precision forming applications, buyers are recommended to provide the target component, wire diameter, material standard, forming process and mechanical property requirements when making an inquiry.
