Product Specification

Micro Stainless Steel Wire 0.15–12mm | Bright Surface Stainless Steel Spring Wire

Product Introduction

Micro stainless steel wire is used for precision wire applications where wire diameter, surface condition, material grade, and mechanical properties need to match the requirements of the finished component.

TOPONE supplies stainless steel wire in 0.15–12 mm diameters, with bright surface options and multiple stainless steel grades including 304, 304L, 316 and 316L. The wire can be specified according to the required material standard, mechanical condition, surface finish, and application.

For spring applications, the wire specification should be selected according to spring geometry, required load, forming process, working environment, and mechanical requirements rather than diameter alone.

Product Specifications

Specific tensile strength, elongation, dimensional tolerance and mechanical condition should be confirmed according to the selected grade, diameter, standard and application.

Stainless Steel Grade Selection

304 Stainless Steel Wire

304 stainless steel wire is a common choice for general-purpose stainless steel wire applications. It can be considered for formed-wire components and spring applications where corrosion resistance and mechanical requirements are suitable.

304L Stainless Steel Wire

304L is a low-carbon version of 304 stainless steel. It can be considered where the application or subsequent processing requires the characteristics associated with a low-carbon stainless steel grade.

316 Stainless Steel Wire

316 stainless steel wire can be selected for applications requiring enhanced corrosion resistance compared with common 304-grade applications, particularly where the working environment needs additional consideration.

316L Stainless Steel Wire

316L is a low-carbon 316 stainless steel grade used in applications where corrosion conditions and material requirements make this grade appropriate.

The final material grade should be selected according to the actual service environment, forming process, mechanical requirements, and applicable standard.

Bright Surface Stainless Steel Wire

The bright surface option provides a cleaner and more reflective wire appearance compared with matte or soap-coated surfaces.

Bright stainless steel wire can be considered for applications where the wire surface is visible or where the production process requires a clean surface condition.

For forming operations where lubrication is important, a soap-coated surface may be more appropriate. Surface selection should therefore be based on both the finished component requirement and the forming process.

Diameter Range: 0.15–12 mm

The current standard diameter range for TOPONE stainless steel wire products is 0.15–12 mm.

The appropriate diameter depends on the finished component and processing requirements.

For spring applications, wire diameter should be evaluated together with:

• Spring type

• Coil diameter

• Working load

• Deflection

• Number of coils

• Forming method

• Required mechanical condition

• Working environment

Therefore, selecting a spring wire only according to nominal diameter may not provide enough information for accurate material selection.

Applications

Micro and fine stainless steel wire can be used in a variety of wire-processing and industrial applications, including:

• Stainless steel spring components

• Precision wire forms

• Small wire-formed parts

• Cable components

• Clothes hangers

• Dish racks

• BBQ mesh

• Industrial wire components

• Clips and retaining parts

• Custom wire products

For spring manufacturing, the selected material grade, diameter, surface, and mechanical condition should be matched to the required spring design.

Product Advantages

Wide Diameter Selection

The 0.15–12 mm range provides options for fine-wire applications as well as larger stainless steel wire components.

Multiple Material Grades

304, 304L, 316 and 316L grades provide different options for corrosion environment and application requirements.

Bright Surface Available

The bright surface is suitable for applications where surface appearance and surface condition are important considerations.

Multiple Applicable Standards

The wire can be specified according to AISI, ASTM, DIN, EN, GB, JIS and corresponding material requirements.

Application-Based Specification

Material grade, diameter, surface, mechanical condition and applicable standard can be evaluated together to select a wire specification suitable for the intended application.

How to Select Micro Stainless Steel Wire

Before ordering micro or fine stainless steel wire, buyers should confirm:

1. Required diameter: 0.15–12 mm

2. Material grade: 304, 304L, 316, 316L or other specified grade

3. Surface: Bright or soap coated

4. Mechanical condition: According to application requirements

5. Tensile strength: If specified by the finished component

6. Dimensional tolerance

7. Application: Spring, wire form, cable, rack, hanger or other component

8. Applicable material standard

9. Packaging: Coil, spool or customized packaging

10. Working environment: Indoor, outdoor, moisture or corrosive conditions

For precision or spring applications, a technical drawing or detailed component specification is recommended.

Micro Stainless Steel Wire for Spring Applications

For spring manufacturing, the term "micro stainless steel wire" describes the relatively small wire size, but the wire must also meet the mechanical requirements of the spring.

The final selection should consider wire diameter, material grade, tensile condition, spring geometry and forming method.

For example, a 304 stainless steel spring wire and a 316 stainless steel spring wire may be considered for different service environments even when the nominal wire diameter is the same.

This application-based selection approach helps avoid choosing a wire specification based only on diameter.
