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:
-
Stainless steel grade
-
Wire diameter
-
Surface condition
-
Cold heading or cold forging process
-
Final component type
-
Required mechanical properties
-
Applicable material standard
-
Coil inner diameter
-
Packaging requirements
-
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.”
