Product Specification

Multi-Grade Stainless Steel Wire for Industrial Applications

Product Introduction

TOPONE multi-grade stainless steel wire is available in 201, 202, 304, 304L, 316, 316L, 410, 420 and 430 grades for industrial wire forming, springs, fasteners, mesh and other stainless steel component applications.

The available diameter range is 0.15–12mm. Different grades, mechanical conditions and surface finishes can be selected according to the forming process, corrosion environment and final application.

For stainless steel wire purchasing, material grade should be evaluated together with diameter, surface condition, mechanical properties and applicable standard. A clear specification helps manufacturers select wire that matches their production process rather than choosing only by nominal grade.

Product Parameters

Exact diameter tolerance, tensile strength, hardness and surface condition should be confirmed according to the selected grade and application.

Stainless Steel Grades

200 Series Stainless Steel Wire

201 and 202 stainless steel wire can be considered for applications where the required material characteristics and corrosion environment are compatible with the selected grade.

These grades can be evaluated for general wire-forming and hardware applications according to the required specification.

304 and 304L Stainless Steel Wire

304 and 304L are widely used stainless steel grades for general industrial applications.

They can be considered for wire forming, fasteners, springs, mesh and other components where the required corrosion resistance and forming characteristics are appropriate.

316 and 316L Stainless Steel Wire

316 and 316L stainless steel wire can be considered for applications where greater corrosion resistance is required under specific service conditions.

Material selection should take into account exposure to moisture, chemicals, salt and other environmental factors.

410 and 420 Stainless Steel Wire

410 and 420 are martensitic stainless steel grades. They can be considered for applications where the required combination of mechanical properties, hardness and corrosion resistance is compatible with the service environment.

430 Stainless Steel Wire

430 is a ferritic stainless steel grade commonly considered for applications requiring suitable corrosion resistance and material characteristics without the need for an austenitic grade.

0.15–12mm Stainless Steel Wire

TOPONE supplies stainless steel wire in diameters from 0.15–12mm.

The appropriate diameter should be determined according to the finished component and production process.

Important selection factors include:

• Finished component dimensions

• Required wire tolerance

• Forming method

• Mechanical condition

• Surface requirement

• Wire feeding equipment

• Applicable material standard

For fine wire, dimensional control and surface condition can be important during automated processing. For larger diameters, forming equipment and mechanical condition should be considered together with the wire size.

Surface Options

Bright Surface

Bright stainless steel wire provides a clean metallic surface and can be selected where surface appearance and wire condition are important.

Soap Coated Surface

Soap-coated wire provides a lubricated surface condition that can be considered for forming operations where friction between the wire and tooling needs to be managed.

Matte Surface

Matte surface wire can be selected where a non-bright finish or specific processing condition is required.

The suitable surface should be determined according to the forming equipment, tooling and lubrication system.

Applications

Spring Manufacturing

Suitable stainless steel grades can be used for compression, extension and torsion springs according to the required material and mechanical condition.

Screw and Fastener Manufacturing

Stainless steel wire can be specified for screw and fastener production where the selected grade and wire condition are compatible with cold heading or other forming processes.

Wire Forming

The wire can be processed into clips, hooks, brackets, retaining components and other formed-wire products.

Wire Mesh

Selected stainless steel grades and diameters can be used for mesh and woven-wire applications according to the required corrosion and mechanical characteristics.

Industrial Hardware

Stainless steel wire can also be used for hardware, appliance components and general industrial metal products.

Product Advantages

Multiple Grade Options

TOPONE provides a broad range of stainless steel grades from 201 and 202 to 304, 304L, 316, 316L, 410, 420 and 430, allowing material selection according to different application requirements.

0.15–12mm Diameter Range

The 0.15–12mm diameter range covers fine stainless steel wire through larger wire sizes for different industrial processing requirements.

Multiple Surface Conditions

Bright, soap-coated and matte surfaces can be selected according to the forming process, tooling and final application.

Different Mechanical Conditions

Annealed and soft conditions can be specified where required, while the final mechanical condition should be confirmed according to the selected grade and production process.

Multiple International Standards

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

How to Select the Right Stainless Steel Wire

1. Identify the Application

Determine whether the wire will be used for springs, fasteners, wire forms, mesh, hardware or another application.

2. Select the Material Grade

Choose the stainless steel grade according to corrosion exposure, mechanical requirements and forming characteristics.

3. Confirm the Diameter

Define the required diameter and tolerance based on the finished product and production equipment.

4. Select the Mechanical Condition

Annealed, soft or other specified conditions should be selected according to the forming process and required mechanical properties.

5. Confirm the Surface

Bright, matte or soap-coated surfaces should be evaluated according to tooling, lubrication and final product requirements.

6. Define the Standard

Confirm the applicable AISI, ASTM, DIN, EN, GB or JIS specification before production.
