Product Specification

304 Stainless Steel Spring Wire 0.15–12mm | 1.8mm Soap Coated

Product Introduction

TOPONE Wire supplies 304 stainless steel spring wire in diameters from 0.15 to 12 mm, including 1.8 mm spring wire, for spring manufacturing, wire forming and industrial components.

This product is supplied with a soap-coated surface according to the specified production condition. Soap coating can be used as a surface treatment for spring wire and may support wire handling and forming processes depending on the customer's equipment and manufacturing method.

304 stainless steel is widely used for spring wire applications where stainless steel corrosion resistance and the mechanical characteristics required for spring forming need to be considered together.

For purchasing, important specifications include stainless steel grade, wire diameter, tensile strength, dimensional tolerance, surface condition, coating condition and applicable standard.

Product Specifications

Technical note: Mechanical properties, dimensional tolerance and surface characteristics depend on wire diameter, production condition and applicable specification. Final values should be confirmed against the production specification or inspection document.

1.8mm 304 Stainless Steel Spring Wire

1.8 mm is a specific diameter within the available 0.15–12 mm range and can be used for spring and wire-forming applications where the spring design requires this wire size.

For 1.8 mm spring wire, buyers should confirm:

• Required tensile strength

• Diameter tolerance

• Spring type

• Surface condition

• Soap coating requirement

• Forming process

• Applicable material standard

• Required quantity and packaging

The correct specification should be selected according to the finished spring design and manufacturing process.

Bright Soap-Coated Surface

This 304 stainless steel spring wire is available with a bright soap-coated surface according to the specified production condition.

Bright Surface

A bright surface provides a cleaner metallic appearance and can be relevant when surface condition is an important part of the wire specification.

Soap Coating

Soap coating is a surface treatment commonly associated with certain spring-wire drawing and forming processes. Its suitability depends on the wire condition, forming equipment, lubrication system and subsequent processing.

For this reason, buyers should specify whether the required wire is soap coated, uncoated or supplied with another surface condition when requesting a quotation.

Why Choose 304 Stainless Steel Spring Wire?

304 stainless steel is a commonly selected austenitic stainless steel grade for spring and wire-forming applications.

For spring manufacturers, material selection should consider several factors together:

• Required spring load

• Wire diameter

• Spring geometry

• Working deflection

• Mechanical properties

• Corrosion environment

• Forming process

• Surface and coating requirements

The stainless steel grade alone does not determine the suitability of a spring wire. The final wire condition and mechanical specification also need to match the spring design.

Applications

304 stainless steel spring wire can be used for a variety of applications, including:

• Compression springs

• Extension springs

• Torsion springs

• Coil springs

• Wire forms

• Retaining clips

• Industrial springs

• Mechanical components

• Fastening components

• Electrical components

• Household hardware

• Customized spring components

The required grade, diameter and mechanical condition should be selected according to the actual application and service environment.

0.15–12mm Diameter Range

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

Different wire sizes may be selected according to spring dimensions and manufacturing requirements.

The ranges above are general application references. The final diameter should be determined by the spring design, required load, working deflection and production equipment.

Product Advantages

304 Stainless Steel

The product uses AISI 304 stainless steel, a commonly used stainless steel grade for general corrosion-resistant wire and spring applications.

0.15–12mm Supply Range

The available diameter range covers fine wire through larger industrial spring-wire requirements, with 1.8 mm available as a specific diameter.

Soap-Coated Surface

A soap-coated surface can be specified for applications where the wire drawing, handling or forming process requires this type of surface treatment.

Bright Surface Condition

The bright surface provides a defined surface condition for applications where wire appearance and surface characteristics are part of the purchasing specification.

Application-Based Specifications

Grade, diameter, tolerance, mechanical condition, surface treatment, coating and packaging can be specified according to the customer's production requirements.

How to Select 304 Stainless Steel Spring Wire

1. Confirm the Wire Diameter

The diameter should be selected according to the spring design and required mechanical characteristics. For this product, 1.8 mm is one available specification within the 0.15–12 mm range.

2. Confirm the Spring Type

Compression, extension and torsion springs have different designs and loading conditions. The wire specification should therefore be matched with the finished spring geometry.

3. Confirm Mechanical Properties

Tensile strength and mechanical condition are important parameters for spring wire. The required values should be confirmed according to the spring design and applicable specification.

4. Confirm Surface and Coating

If the production process requires a soap-coated wire, the coating condition should be clearly specified before production.

5. Confirm the Standard

Where an ASTM or customer-specific standard is required, the applicable specification should be confirmed before production.

Quality and Technical Documentation

For industrial spring-wire purchasing, product quality should be evaluated through measurable technical information.

Depending on project requirements, the product specification can include:

• Stainless steel grade

• Chemical composition

• Wire diameter

• Diameter tolerance

• Tensile strength

• Mechanical condition

• Surface condition

• Soap coating condition

• Applicable standard

• Inspection requirements

• Packaging specification

Where required, material and inspection documentation can be discussed before production.
