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

Product Introduction

TOPONE 1.6mm 304H Soap-Coated Stainless Steel Spring Wire is designed for spring manufacturing, wire forming, screws, fishing components, and other industrial applications requiring high-tensile stainless steel wire.

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

The wire is manufactured from AISI 304H stainless steel and can be supplied with a soap-coated or bright surface. The soap-coated surface provides a lubricated condition that can be considered for wire drawing and spring coiling processes where surface lubrication is required.

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

Product Specifications

*Reference values for the listed specification. Final tensile strength, tolerance, temper, and other mechanical requirements should be confirmed according to the actual grade, diameter, production condition, and applicable standard.

Why Choose 304H Stainless Steel Spring Wire?

AISI 304H stainless steel is used for applications requiring a stainless steel wire with a defined mechanical condition for spring and cold-forming processes.

For spring manufacturing, the final wire performance is affected by material grade, diameter, cold-working condition, tensile strength, surface condition, and forming process.

Therefore, the wire specification should be selected according to the finished spring design rather than tensile strength alone.

1.6mm Wire Specification

The standard product specification for this page is 1.6 mm 304H stainless steel spring wire.

The reference tensile strength is 1750–2000 MPa, while the listed diameter tolerance is ±0.015 mm.

These parameters can be used as the initial technical reference for spring manufacturers and wire-forming companies. For customized orders, the required diameter, tolerance, tensile strength, surface condition, and temper should be confirmed before production.

0.15–12 mm Diameter Range

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

Different diameters are suitable for different spring sizes and wire-forming requirements. The final selection should consider:

• Finished component dimensions

• Spring design

• Required load

• Forming equipment

• Tensile strength

• Diameter tolerance

• Surface condition

• Production process

For precision spring production, the nominal diameter and required tolerance should be specified separately.

Soap-Coated Surface

Soap-coated stainless steel wire provides a lubricated surface condition for certain wire drawing and spring-forming processes.

During spring coiling, surface lubrication can be relevant to contact between the wire, tooling, and forming equipment.

The appropriate surface condition should be selected according to the customer's:

• Spring coiling process

• Drawing process

• Tooling

• Lubrication system

• Surface appearance requirements

• Subsequent processing

For applications where a clean metallic appearance is required, a bright surface can be considered instead.

Bright Surface Option

Bright stainless steel wire is also available for applications where surface appearance and a clean metallic finish are important.

The choice between bright and soap-coated surface should be based on the forming process and finished product requirements rather than surface appearance alone.

Applications

Compression Springs

304H stainless steel spring wire can be used for compression spring manufacturing when the selected wire specification matches the spring design and required mechanical condition.

Extension Springs

The wire can be considered for extension springs and other tension-loaded spring components according to the required tensile condition and forming process.

Torsion Springs

For torsion springs, wire diameter, tensile condition, surface condition, and forming process should be evaluated together.

Wire Forming

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

Screw and Hardware Components

The product can be used for selected screw, hardware, and mechanical components where the required stainless steel grade and mechanical condition are suitable.

Fishing Components

304H stainless steel spring wire can also be used for selected fishing hooks, fishing reels, and related formed-wire components according to the required specification.
