304H Stainless Steel Spring Wire 0.15–12mm for Spring Forming

Product Introduction

TOPONE 304H stainless steel spring wire is designed for manufacturers producing springs, formed-wire components and other industrial products.

Made from AISI 304H stainless steel, this cold-drawn round wire is available in diameters from 0.15mm to 12mm. Bright and soap-coated surface options are available according to different processing and application requirements.

304H is a high-carbon austenitic stainless steel grade. Its material characteristics make it an option for applications requiring specific mechanical properties and corrosion resistance.

For spring manufacturing, wire diameter, tensile strength, mechanical condition and surface finish should be selected according to the spring design and production process.

Product Specifications

What Is 304H Stainless Steel Spring Wire?

304H is a high-carbon version of 304 austenitic stainless steel. The higher carbon content distinguishes it from standard 304 and 304L grades.

It can be considered for industrial applications where the specific material composition and mechanical properties meet the requirements.

When selecting 304H spring wire, buyers should consider the material standard, wire diameter, tensile strength, mechanical condition and working environment together.

Product Features

1. 304H Stainless Steel Material

304H provides a distinct material option within the 304 stainless steel family. Its chemical composition should be verified against the applicable material standard and inspection requirements.

2. Wide Diameter Range

Available in diameters from 0.15mm to 12mm, covering different spring manufacturing and industrial wire-forming requirements.

3. Cold Drawn Processing

Cold drawing reduces the wire diameter and develops the required mechanical condition through controlled deformation. Final tensile strength and other properties depend on the material, diameter and drawing process.

4. Bright and Soap-Coated Surfaces

Bright wire is available for applications requiring a clean metallic surface. Soap-coated wire can be considered for selected drawing and spring-forming processes where surface lubrication is required.

5. Multiple Supply Forms

Coil and spool packaging options are available to accommodate different production equipment and handling requirements.

Applications of 304H Stainless Steel Spring Wire

Compression Springs

304H wire can be considered for compression spring production where its material properties meet the spring design and operating requirements.

Extension Springs

The wire can be evaluated for extension spring manufacturing according to the required tensile properties, spring geometry and working load.

Torsion Springs

For torsion spring applications, material grade and mechanical condition should be matched with the required torque, spring dimensions and operating conditions.

Industrial Wire Forms

304H stainless steel wire can also be used for selected formed-wire components, screws and other industrial products, subject to processing requirements.

Fishing Components

The wire can be considered for selected fishing equipment components, including spring mechanisms and other formed-wire parts.

How to Select 304H Stainless Steel Spring Wire

1. Confirm the Material Grade

Specify AISI 304H or the applicable equivalent designation. Material composition should be checked against the required standard.

2. Choose the Wire Diameter

TOPONE supplies diameters from 0.15mm to 12mm. The required size should match the spring drawing and production equipment.

3. Define Mechanical Properties

Provide the required tensile strength, hardness and elongation where applicable. These properties depend on the wire diameter and delivery condition.

4. Select the Surface Finish

Choose bright or soap-coated wire according to the spring-forming process, tooling and surface requirements.

5. Confirm the Packaging

Specify the preferred coil or spool form, coil weight and packaging requirements before production.

Quality Control Considerations

For 304H stainless steel spring wire, the following parameters should be included in the technical specification:

• Material grade and chemical composition

• Wire diameter and tolerance

• Tensile strength

• Hardness and elongation, where required

• Surface condition

• Coil weight and packaging

• Applicable material standard

Material test certificates and inspection requirements should be confirmed with the supplier before production.

Frequently Asked Questions

What is 304H stainless steel spring wire?

It is spring wire made from 304H high-carbon austenitic stainless steel, used for selected spring manufacturing and industrial wire-forming applications.

What is the difference between 304 and 304H?

304H has a higher carbon content than standard 304. The two grades have different material specifications and should not be treated as interchangeable without checking the applicable standard and application requirements.

What diameters are available?

TOPONE supplies 304H stainless steel wire in diameters from 0.15mm to 12mm.

What surface finishes are available?

Bright and soap-coated surface options are available, subject to the required product specification.

Can 304H wire be used for compression and torsion springs?

It can be evaluated for these applications. The suitability depends on the spring design, required mechanical properties and working environment.

What information is needed for a quotation?

Please provide the material grade, diameter, tensile strength, surface finish, spring type, quantity, applicable standard and packaging requirements.
