Product Specification

0.5mm AISI 304 Soap-Coated Stainless Steel Spring Wire

Product Overview

The 0.5mm AISI 304 Soap-Coated Stainless Steel Spring Wire is a fine stainless steel wire designed for spring manufacturing, wire forming and other applications requiring a defined small wire diameter.

Made from AISI 304 stainless steel, this wire is supplied with a soap-coated surface for downstream processing where a lubricated wire condition is required. The 0.5mm diameter provides a fine-wire option for small springs and formed-wire components.

For spring manufacturing, the appropriate wire condition should be selected according to the required tensile strength, spring geometry, forming process and working conditions. Diameter, tolerance and surface condition should be confirmed according to the customer's drawing or applicable material specification.

Product Specifications

AISI 304 Stainless Steel for Spring Wire

AISI 304 is an austenitic stainless steel grade widely used in stainless steel wire products and various industrial forming applications.

For spring wire, material grade is only one part of the selection process. The final suitability of 0.5mm wire depends on the wire condition, diameter tolerance, tensile strength, surface condition and requirements of the finished spring.

When ordering 0.5mm 304 spring wire, buyers should consider:

• Nominal wire diameter

• Diameter tolerance

• Tensile strength

• Wire condition

• Surface finish

• Spring type

• Forming method

• Applicable material standard

• Inspection requirements

This specification-based approach provides a clearer basis for matching the wire to the customer's production process.

0.5mm Fine Wire Diameter

The 0.5mm diameter is a fine-wire specification for applications where a relatively small stainless steel wire size is required.

For spring production, wire diameter should be considered together with the complete spring geometry. Important parameters may include:

• Wire diameter

• Mean spring diameter

• Number of active coils

• Working load

• Spring deflection

• Forming method

• Required mechanical condition

A specific wire diameter should therefore be selected from the actual spring design rather than from diameter alone.

Soap-Coated Surface

The soap-coated surface provides a lubricated condition for selected downstream wire processing and forming operations.

This surface may be considered when the manufacturing process requires lubrication between the wire and forming equipment. The appropriate coating condition should be confirmed according to the customer's production process, equipment and subsequent cleaning requirements.

For applications where a clean metallic surface is preferred, a bright surface can also be supplied as an alternative configuration.

Typical Applications

Small Compression Springs

0.5mm 304 stainless steel spring wire can be used for selected compression spring applications when the wire condition and mechanical properties match the spring design.

Extension Springs

For extension springs, the wire specification should be selected according to the spring geometry, working load, forming process and required mechanical condition.

Torsion Springs

The wire can be considered for selected torsion spring applications where the 0.5mm diameter and specified material condition are appropriate for the finished component.

Wire Forms

0.5mm stainless steel wire can be processed into formed-wire components requiring a fine wire diameter and specified surface condition.

Small Industrial Components

The wire may also be used for selected small formed components where stainless steel material and a defined wire diameter are required.

Product Advantages

0.5mm Fine Diameter

The 0.5mm nominal diameter provides a defined fine-wire option for small spring and wire-form applications.

AISI 304 Material

AISI 304 provides a commonly used stainless steel material option for wire products and forming applications. The final wire condition should be selected according to the required mechanical and processing characteristics.

Soap-Coated Surface

The soap-coated surface provides a lubricated condition for downstream processing where additional surface lubrication is required.

Flexible Wire Conditions

Hard or soft wire conditions can be discussed according to the customer's required mechanical specification and forming process.

Alternative Surface Available

In addition to soap-coated wire, a bright surface can be discussed when the downstream application requires a clean metallic surface without a soap coating.

Bright vs. Soap-Coated Surface

Surface selection should be based on the actual manufacturing process.

For this product, soap coated is the primary surface specification. Bright surface can be considered when the customer's processing requirements are different.

Quality Control

For fine stainless steel spring wire, quality should be assessed using measurable specifications.

Recommended inspection items include:

• Material grade

• Chemical composition

• Wire diameter

• Diameter tolerance

• Tensile strength

• Surface condition

• Coil or spool weight

• Material traceability

• Packaging condition

• Required inspection documentation

For spring applications involving repeated loading, the finished spring should be evaluated according to its actual design and operating conditions.

How to Select 0.5mm 304 Spring Wire

1. Confirm the Diameter

Specify the required nominal diameter and dimensional tolerance.

2. Confirm the Material Grade

Specify AISI 304 or the applicable equivalent material standard.

3. Select the Surface

Choose soap coated when the downstream process requires a lubricated surface condition. Bright surface can be discussed for alternative processing requirements.

4. Confirm the Mechanical Condition

Provide the required tensile strength, hardness or wire condition where applicable.

5. Specify the Application

Indicate whether the wire will be used for compression springs, extension springs, torsion springs, wire forms or another component.

6. Confirm Packaging

Coil, spool or pallet packaging can be selected according to the customer's production and handling requirements.

Ordering Information

For technical confirmation and production planning, buyers are recommended to provide:

• Diameter: 0.5mm

• Material: AISI 304

• Surface: Soap Coated

• Required quantity

• Tensile strength or hardness

• Application

• Applicable standard

• Packaging requirement

• Inspection or certification requirements

Providing these details allows the wire specification to be matched more closely to the customer's downstream manufacturing process.
