Fine Stainless Steel Wire 0.15–12mm for Precision Components

Product Specification

TOPONE Wire supplies fine stainless steel wire for precision components, wire forming, spring manufacturing, and industrial production.

Available in diameters from 0.15mm to 12mm, the product range includes stainless steel grades such as 201, 302, 304, 316, and 316L, subject to the required specification. Bright and soap-coated surface options are available for different processing requirements.

For precision manufacturing, selecting the right wire involves more than choosing a nominal diameter. Material grade, dimensional tolerance, surface condition, mechanical properties, and processing requirements should be considered together to match the wire to the finished component.

TOPONE Wire supports specification-based customization to help manufacturers select suitable stainless steel wire for their production processes.

Product Specifications

Note: Confirm the available material grade, wire condition, mechanical properties, dimensional tolerance, and applicable standard for the selected specification before ordering.

Product Advantages

1. Fine Diameter Selection from 0.15mm to 12mm

The wide diameter range supports different wire-processing requirements, from fine-wire components to larger industrial wire products.

For precision applications, nominal diameter and dimensional tolerance should be specified separately according to the component drawing or applicable standard.

2. Multiple Stainless Steel Grade Options

Different stainless steel grades offer different combinations of corrosion resistance and mechanical properties.

• 201: Considered for applications where its specific material properties meet the requirements.

• 302: Commonly used in selected spring-wire applications.

• 304: Widely used for general industrial wire and formed components.

• 316 / 316L: Considered for applications requiring enhanced corrosion resistance in suitable environments.

The final grade should be selected according to the operating environment, forming process, and technical requirements of the finished component.

3. Bright and Soap-Coated Surface Options

Bright wire provides a clean metallic surface for applications where surface appearance and condition are important.

Soap-coated wire provides a lubricated surface condition that may be suitable for certain drawing and forming operations.

The appropriate surface should be selected according to tooling, lubrication requirements, downstream processing, and finished-product specifications.

4. Specification-Based Mechanical Properties

Tensile strength, elongation, hardness, and wire condition can influence forming behavior and finished-component performance.

For precision manufacturing, these properties should be confirmed according to the selected grade, diameter, processing condition, and applicable standard.

5. Coil and Spool Packaging Options

Coil or spool packaging can be selected according to wire diameter, handling equipment, production-line feeding requirements, and transportation needs. Packaging format and unit weight should be confirmed before ordering.

Applications

Precision Wire Components

Fine stainless steel wire can be processed into small metal components where material grade, diameter, and surface condition need to meet defined manufacturing requirements.

Spring Manufacturing

Selected stainless steel wire grades and mechanical conditions can be used for small springs and other spring components when the wire specification matches the spring design.

Custom Wire Forms

Fine stainless steel wire can be formed into clips, hooks, retaining components, and other custom wire forms according to the required geometry.

Cables and Wire Assemblies

Suitable stainless steel wire can be used in selected cable and wire-assembly applications, depending on the required construction, material properties, and end-use conditions.

Kitchen and Household Wire Products

Depending on the selected grade and surface finish, stainless steel wire can be used for racks, baskets, holders, and other kitchen or household wire products.

How to Select Fine Stainless Steel Wire

1. Confirm the Material Grade

Specify the required grade according to corrosion exposure, mechanical properties, and application requirements.

2. Define the Wire Diameter and Tolerance

Confirm the nominal diameter and acceptable dimensional tolerance. For fine wire applications, dimensional accuracy can be a critical part of the component specification.

3. Choose the Surface Finish

Select bright or soap-coated wire according to the forming process, lubrication method, and required surface condition.

4. Specify Mechanical Properties

Define the required tensile strength, elongation, hardness, or wire condition where applicable. These values should be based on the intended processing method and finished-product requirements.

5. Confirm the Applicable Standard

Identify the required material or product standard and inspection criteria. The applicable standard should match the selected grade and product specification.

6. Select the Packaging

Specify coil or spool packaging, preferred unit weight, and any special handling requirements.

Quality Inspection

For precision wire applications, quality requirements should be defined using measurable technical parameters.

Depending on the order specification, inspection may include:

• Material grade verification

• Wire diameter and dimensional tolerance

• Surface condition

• Tensile strength and other specified mechanical properties

• Packaging and product identification

• Batch traceability, where applicable

The inspection method and acceptance criteria should be agreed upon before production.
