Product Specification

1.6mm 304H Soap-Coated Stainless Steel Spring Wire | 0.15–12mm

Product Introduction

TOPONE 1.6mm 304H Soap-Coated Stainless Steel Spring Wire is manufactured from AISI 304H stainless steel for spring manufacturing, wire forming and selected industrial applications.

The standard product specification is 1.6mm diameter, with an available diameter range of 0.15–12mm. The wire can be supplied with a soap-coated or bright surface, allowing the surface condition to be matched with different spring coiling and forming processes.

For this product specification, the listed tensile strength is 1750–2000 MPa and the diameter tolerance is ±0.015mm. These values provide measurable technical references for buyers evaluating the wire for spring production. Final mechanical requirements should be confirmed according to diameter, temper, spring design and applicable standard.

* Mechanical properties and dimensional tolerances should be confirmed according to the specific diameter, production condition and purchase specification.

Key Product Features

304H Stainless Steel Material

304H is a member of the 304 stainless steel family with a higher carbon designation than standard 304. For industrial spring-wire purchasing, specifying the exact grade helps buyers align the material with their required chemical composition and manufacturing conditions.

Material selection should be based on the required grade, mechanical properties, forming process and service environment rather than relying only on the general term "304 stainless steel."

1.6mm Spring Wire with 0.15–12mm Availability

The featured product is supplied in 1.6mm diameter, while TOPONE's available range for this product family is 0.15–12mm.

Diameter selection should be considered together with spring geometry, wire-forming equipment, required tensile strength and the intended working conditions.

1750–2000 MPa Tensile Strength

The listed tensile strength for the 1.6mm specification is 1750–2000 MPa.

For spring manufacturing, tensile strength should be evaluated together with wire diameter, spring index, forming method and required working load. A higher tensile value alone does not determine whether a particular wire is suitable for a specific spring design.

Soap-Coated Surface

The soap-coated surface is intended for wire-forming processes where the surface condition and lubrication during spring coiling need to be considered.

The appropriate surface should be selected according to the customer's coiling equipment, tooling, forming process and subsequent cleaning or finishing requirements.

Bright Surface Option

A bright surface is also available when the production process requires a different surface condition.

For industrial procurement, surface finish should be specified clearly together with material grade, diameter, tensile strength and applicable standard.

Applications

Compression Springs

The 1.6mm 304H stainless steel spring wire can be considered for compression spring production where the specified material and mechanical properties match the spring design.

Extension Springs

The wire can also be used for selected extension spring applications. Final suitability should be evaluated according to spring dimensions, required load and working conditions.

Torsion Springs

For torsion spring manufacturing, buyers should evaluate wire diameter, tensile strength, spring geometry and forming requirements together before selecting the material.

Wire-Formed Components

304H stainless steel spring wire can also be considered for selected wire-forming applications where the specified material, diameter and surface condition are suitable.

Technical Selection Guide

When purchasing 1.6mm 304H stainless steel spring wire, buyers should provide more than the basic material and diameter.

The following information is recommended:

1. Material grade: 304H

2. Wire diameter: 1.6mm or required size

3. Diameter tolerance

4. Required tensile strength

5. Temper or mechanical condition

6. Surface finish: soap coated or bright

7. Spring type

8. Spring dimensions and drawing

9. Applicable technical standard

10. Working environment and temperature

11. Required coil weight and packaging

This specification-based approach allows the wire supplier to evaluate the product against the customer's actual spring manufacturing requirements.

Quality Control

For stainless steel spring wire, quality should be evaluated using measurable production and inspection parameters.

Depending on the order specification, quality control may include:

Raw Material Verification

The stainless steel grade and relevant material documentation can be checked against the agreed specification.

Diameter Inspection

The wire diameter can be measured to verify compliance with the specified nominal diameter and tolerance.

Tensile Strength Testing

Tensile strength can be tested according to the applicable technical specification.

For the listed 1.6mm product, the specified tensile strength is 1750–2000 MPa.

Surface Inspection

The soap-coated or bright surface can be inspected for the required surface condition before shipment.

Coil and Packaging Inspection

Coil dimensions, coil weight and packaging condition can be checked before dispatch according to the agreed order requirements.

Standards and Documentation

The applicable standard should be confirmed according to the exact material, diameter, mechanical condition and customer specification.

The current product page lists ASTM A313, ASTM A580, JIS G4314 and EN 10270-3 as applicable standards. These standards should not be treated as interchangeable; the specific standard and grade designation should be agreed before production.

For B2B procurement, technical documentation may include:

• Material specification

• Chemical composition documentation

• Diameter inspection

• Tensile test report

• Surface inspection

• Mill Test Certificate (MTC), when required

FAQ

What is 1.6mm 304H stainless steel spring wire?

It is stainless steel spring wire manufactured from AISI 304H material with a nominal diameter of 1.6mm. It is intended for selected spring manufacturing and wire-forming applications.

What diameter range is available?

The available diameter range is 0.15–12mm, with 1.6mm as the featured specification.

What is the tensile strength of the 1.6mm wire?

The listed tensile strength for the 1.6mm specification is 1750–2000 MPa. The actual required tensile strength should be confirmed according to the production condition and customer's technical specification.

Related Stainless Steel Spring Wire Selection

For customers comparing different stainless steel spring wire grades, TOPONE can provide product options including 302, 304, 304H, 316 and 430 series materials.

The appropriate grade should be selected according to:

Material → Diameter → Tensile Strength → Surface → Spring Type → Working Environment → Applicable Standard

This approach provides a more practical basis for industrial spring-wire selection than comparing material grades by name alone.
