Product Specification

1.6mm 304H Soap-Coated Stainless Steel Spring Wire for High-Tensile Forming

Product Introduction

1.6mm 304H soap-coated stainless steel spring wire is designed for spring manufacturing, wire forming and industrial components requiring defined mechanical properties and controlled forming performance.

Manufactured from AISI 304H stainless steel, this spring wire is suitable for applications where wire diameter, tensile strength, surface condition and forming process need to be considered together.

The standard specification of this product is 1.6mm diameter, while the available stainless steel spring wire range is 0.15–12 mm according to production requirements.

The wire can be supplied with a soap-coated or bright surface. The soap-coated surface provides a lubricated condition that can be considered for spring coiling, wire drawing and forming processes where surface lubrication is required.

For the 1.6mm specification, the reference tensile strength is 1750–2000 MPa, with a diameter tolerance of ±0.015mm according to the applicable production specification.

Product Specifications

*Final tensile strength, tolerance and mechanical requirements should be confirmed according to diameter, production condition and applicable standards.

Why Choose 304H Stainless Steel Spring Wire?

AISI 304H Stainless Steel Material

AISI 304H stainless steel is selected for spring wire applications where a defined stainless steel grade and mechanical condition are required.

For spring manufacturing, the final component performance depends on multiple factors, including material grade, wire diameter, forming process, surface condition and working environment.

Therefore, wire selection should be based on the complete spring design rather than tensile strength alone.

High Tensile Strength Specification

For the listed 1.6mm specification, the reference tensile strength is 1750–2000 MPa.

This measurable parameter provides a technical reference for spring manufacturers evaluating the wire for forming applications.

The suitable tensile range should be confirmed according to the spring design, forming equipment and required working conditions.

Soap-Coated Surface for Spring Forming

Lubricated Surface Condition

The soap-coated surface provides a lubricated wire condition that can be considered for spring coiling and wire-forming processes.

During forming, the interaction between wire surface, tooling and lubrication system can influence the production process.

The suitable surface condition should be selected according to:

• Spring coiling equipment

• Tooling design

• Forming speed

• Lubrication requirements

• Final product requirements

Bright Surface Option

Bright surface 304H stainless steel spring wire is also available for applications requiring a clean metallic appearance.

The choice between soap-coated and bright surface should be based on the forming process and finished component requirements.
