Product Specification

Custom Stainless Steel Spiral Springs for Reliable Wire Forming

Product Introduction

TOPONE supplies custom stainless steel spiral springs for industrial wire forming, mechanical assemblies, and customized formed-wire components.

The springs are manufactured from stainless steel wire with a wire diameter range of 0.15–12mm. Material grade, wire diameter, spring dimensions, surface condition, and forming geometry can be selected according to the application and technical requirements.

For customized spring projects, the final specification should be confirmed based on the required working conditions, technical drawing, or physical sample.

Product Specifications

Stainless Steel Material Selection

Material selection should be based on the application environment, forming requirements, operating conditions, and required material characteristics.

300 Series Stainless Steel

Grades such as 301, 302, 304, 304L, 304H, 304N, 316L, and 321 are available for different spring and wire-forming applications.

304 stainless steel is commonly considered for general industrial applications, while 316L can be considered for applications exposed to more demanding corrosion environments.

400 Series Stainless Steel

410, 420, and 430 stainless steel grades are available for applications requiring the characteristics of ferritic or martensitic stainless steel.

The appropriate grade should be confirmed according to the application, working environment, and applicable material standard.

Surface Options

Bright Surface

Bright stainless steel wire provides a clean metallic surface and can be selected when surface appearance and a defined wire surface condition are important to the finished component.

Soap-Coated Surface

Soap-coated stainless steel wire provides a lubricated surface condition that can be suitable for wire forming processes.

The appropriate surface should be selected according to the forming equipment, tooling, and production process.

Custom Spiral Spring Dimensions

Custom stainless steel spiral springs can be manufactured according to application-specific dimensions.

Important design parameters may include:

• Wire diameter

• Outer diameter

• Inner diameter

• Spring length

• Pitch

• Number of turns

• Forming direction

• End configuration

• Material grade

• Surface condition

For applications with strict dimensional requirements, a technical drawing or physical sample is recommended as the main production reference.

Applications

Industrial Mechanical Components

Custom stainless steel spiral springs can be used as formed-wire components in industrial mechanical assemblies where a stainless steel spring element is required.

Wire Form Components

The product can be customized for different formed-wire applications, including:

• Retaining components

• Clips

• Hooks

• Formed wire parts

• Spring assemblies

• Mechanical wire components

Spring Assemblies

Customized spring dimensions can be developed according to the required installation space and component geometry.

The final specification should consider the required load, movement, working environment, and installation conditions.

Industrial Equipment

Stainless steel spiral springs can be used in industrial equipment and mechanical assemblies when the selected stainless steel grade and spring geometry are suitable for the operating environment.

Product Advantages

1. Wide 0.15–12mm Wire Diameter Range

TOPONE supports stainless steel wire diameters from 0.15mm to 12mm, covering fine-wire forming and larger industrial wire-forming requirements.

2. Multiple Stainless Steel Grades

A range of 200, 300, and selected 400 series stainless steel grades is available.

Material selection can be based on the application environment, forming requirements, and required material characteristics.

3. Customized Spring Dimensions

Wire diameter, finished spring diameter, length, pitch, number of turns, and forming geometry can be specified according to customer drawings or samples.

This allows the spring design to be matched to different installation spaces and component requirements.

4. Multiple Surface Options

Bright and soap-coated surface options are available.

Surface selection can be matched to the wire-forming process, tooling, and final application requirements.

5. Drawing-Based Production

Customers can provide a technical drawing, physical sample, or detailed specification for customized projects.

The production requirements can then be confirmed based on material grade, wire diameter, finished dimensions, surface condition, and forming geometry.

Quality and Specification Control

For customized stainless steel spiral springs, product quality should be evaluated against clearly defined technical specifications.

Key inspection and specification items may include:

• Stainless steel grade

• Wire diameter

• Diameter tolerance

• Surface condition

• Finished spring diameter

• Spring length

• Number of turns

• Pitch

• End configuration

• Applicable standard

• Packaging requirements

For precision applications, the approved technical drawing or sample should be used as the primary reference for production and inspection.

How to Specify a Custom Spiral Spring

Before requesting a quotation, buyers can prepare the following information:
