SUS304 316L Fine Stainless Steel Wire for Precision Applications

Product Introduction

TOPONE Wire supplies SUS304 and 316L fine stainless steel wire for precision wire processing, fine wire forming and industrial applications requiring small wire diameters and defined mechanical properties.

The product series covers stainless steel wire specifications from 0.15–12mm, with fine-wire examples including 0.18mm, 0.35mm and 0.5mm.

For applications requiring higher tensile strength, the wire specification should be selected according to the required diameter, material grade, mechanical condition, processing method and applicable standard.

304 and 316L provide different material options for industrial applications. The appropriate grade should be selected according to the service environment, corrosion requirements and final application.

Product Parameters

Technical Note: Tensile strength, elongation, hardness and dimensional tolerance should be confirmed according to the selected grade, diameter, applicable standard and customer's processing requirements.

Application Fields

Precision Wire Components

Fine stainless steel wire can be used for precision wire components where small wire diameter and controlled dimensional specifications are required.

The wire diameter and tolerance should be selected according to the finished component and processing method.

Fine Wire Drawing

SUS304 and 316L stainless steel wire can be used as material for further fine drawing and secondary wire processing.

For multi-stage drawing, the starting wire condition should be matched with the customer's equipment, reduction sequence and target diameter.

Industrial Wire Processing

The wire can be used in various industrial applications involving fine wire forming, cutting, bending or other secondary processing.

The material grade and mechanical condition should be selected according to the finished component and operating environment.

Fine Mesh and Wire Products

Small-diameter stainless steel wire can also be processed into fine mesh and other wire-based products.

For these applications, wire diameter, tolerance, surface condition and mechanical properties should be specified according to the finished product requirements.

Product Advantages

SUS304 and 316L Material Options

The product is available in SUS304 and 316L stainless steel, providing material options for different industrial applications.

The grade should be selected according to the required chemical composition, service environment and applicable material standard.

Fine Diameter Capability

The product series covers 0.15–12mm, with fine-wire specifications such as 0.18mm, 0.35mm and 0.5mm available for applications requiring small wire diameters.

For precision applications, diameter tolerance should be specified together with the nominal diameter.

High Tensile Strength Options

For applications requiring higher tensile strength, mechanical properties can be specified according to the selected material grade, diameter, processing condition and applicable standard.

The required tensile strength should be confirmed before production rather than using one fixed value for all diameters.

Controlled Surface Options

Available surface conditions can include:

• Bright

• Soap Coated

Surface selection should be based on the customer's downstream processing, tooling and lubrication requirements.

Specification-Based Customization

The wire specification can be defined according to:

• Stainless steel grade

• Diameter

• Diameter tolerance

• Tensile strength

• Mechanical condition

• Surface treatment

• Applicable standard

• Coil or spool requirements

• Packaging requirements

This provides a clearer technical basis for purchasing, production and incoming inspection.

Fine Stainless Steel Wire Selection Guide

1. Confirm the Finished Wire Diameter

The first step is to identify the required finished wire diameter.

The product series covers 0.15–12mm, while typical fine-wire specifications include 0.18mm, 0.35mm and 0.5mm.

For precision applications, the required diameter tolerance should be specified together with the nominal diameter.

2. Select SUS304 or 316L

The material grade should be selected according to the application environment and required material properties.

SUS304 can be considered for general stainless steel wire applications, while 316L can be considered where the application requires the characteristics associated with a molybdenum-containing stainless steel grade.

The final grade should be confirmed according to the applicable material standard and service environment.

3. Define Mechanical Requirements

If the application requires high tensile strength, the purchasing specification should define the required mechanical properties.

Depending on the application, buyers may need to specify:

• Tensile strength

• Elongation

• Hardness

• Mechanical condition

These values should correspond to the selected diameter and material grade.

4. Confirm Surface Condition

The surface can affect downstream processing, especially for fine wire drawing, forming and precision applications.

Available options include:

• Bright

• Soap Coated

The surface should be selected according to the customer's equipment, lubricant and processing sequence.

5. Confirm the Applicable Standard

The purchasing specification should identify the required standard, such as:

• ASTM

• JIS

• EN

• DIN

• GB

This provides a clear technical reference for material composition, mechanical properties and inspection requirements.

Quality and Specification Control

For fine stainless steel wire, measurable specifications are important for both production and incoming inspection.

For repeat orders, maintaining the agreed material grade, diameter, tolerance, mechanical condition, surface treatment and applicable standard provides a clear technical reference for production consistency.
