0.15–12mm 304H Tempered Stainless Steel Spring Wire for Fishing Hook and Reel

Product Specification

304H Tempered Stainless Steel Spring Wire for Fishing Hook and Reel Springs

304H tempered stainless steel spring wire is designed for spring-forming applications where the wire requires a defined material grade, diameter and mechanical condition.

The wire is available in diameters from 0.15 mm to 12 mm and can be supplied in a hard or tempered condition according to the required spring-forming and mechanical specifications. Bright and soap-coated surface options can be selected according to the subsequent processing requirements.

For fishing equipment applications, 304H spring wire can be used for components such as fishing hook springs, fishing reel springs and other small spring mechanisms where the wire diameter, spring geometry and mechanical properties need to match the finished component design.

Customers can provide the required wire diameter, spring type, tensile strength, surface condition, forming requirements and application for technical evaluation before production.

Product Specifications

Note: Tensile strength, elongation, diameter tolerance and other mechanical properties should be confirmed according to the specific wire diameter and applicable technical standard.

304H Stainless Steel for Spring Wire

Material Characteristics

304H is a high-carbon version of 304 stainless steel. For spring-wire applications, material selection should be considered together with the required wire diameter, cold-working condition, tensile strength and final spring design.

The appropriate specification should be established according to the actual spring application rather than selecting the material grade independently from the finished component requirements.

For fishing hook and reel spring applications, buyers should consider:

• Wire diameter
• Spring type
• Spring index
• Coil diameter
• Number of active turns
• Required load
• Working deflection
• Operating environment
• Surface condition
• Required fatigue performance

This parameter-based approach provides a more practical basis for selecting stainless steel spring wire.

Tempered and Hard Spring Wire

Wire Condition for Spring Forming

The wire condition directly affects how the material behaves during spring forming.

For 304H spring wire, the supplied condition can be specified according to the required mechanical properties and forming process.

Important parameters include:

• Tensile strength
• Elongation
• Diameter
• Diameter tolerance
• Surface condition
• Spring-forming method

The final wire condition should be selected according to the spring manufacturing process and required finished-spring properties.

Diameter Range: 0.15–12 mm

The available diameter range is 0.15–12 mm, covering fine spring wire through larger-diameter spring-wire requirements.

Different wire diameters can be selected according to the spring design and required load conditions.

For fishing hook and reel spring applications, the wire diameter should be evaluated together with:

• Spring outside diameter
• Spring inside diameter
• Coil pitch
• Number of turns
• Spring type
• Required working load
• Available installation space

The actual wire diameter and tolerance should be confirmed according to the finished spring drawing or technical specification.

Surface Options

Bright Surface

Bright stainless steel spring wire can be considered when the surface appearance of the wire or finished spring is important.

The bright surface can also be selected for applications where the wire will undergo additional forming or assembly processes that require a defined surface condition.

Soap-Coated Surface

Soap-coated spring wire provides a lubricated surface condition that can be suitable for subsequent spring forming processes.

The appropriate coating condition should be selected according to the customer's spring-forming equipment and production process.

For high-speed or automated spring production, the surface condition should be confirmed with the actual forming equipment before production.

Applications

Fishing Hook Springs

304H stainless steel spring wire can be used for small spring components associated with fishing hook mechanisms.

The wire diameter and mechanical condition should be selected according to the spring geometry, required opening or closing force and available installation space.

Fishing Reel Springs

The wire can also be used for spring components in fishing reels where compact spring dimensions and defined mechanical properties are required.

Depending on the reel design, the finished spring may operate under compression, torsion or other loading conditions.

Compression Springs

304H spring wire can be used for compression spring production when the material grade and mechanical condition are suitable for the required design.

Important design parameters include free length, outside diameter, wire diameter, number of coils and working load.

Torsion Springs

For torsion springs, the wire diameter, coil diameter, leg configuration and required torque should be evaluated together when selecting the spring wire.

Extension Springs

The material can also be considered for extension spring applications where the wire specification matches the required spring geometry and working conditions.

The product can be developed for fishing hook springs, fishing reel springs and other small spring components according to customer drawings or samples.

Spring Wire Selection Guide

What Parameters Should Be Confirmed?

Selecting spring wire based only on the material grade is not sufficient. The finished spring design should also be considered.

This information helps determine whether the selected spring wire is suitable for the actual spring-forming process.

Manufacturing Process

304H Stainless Steel Spring Wire Production

The production process can include:

Raw Material → Wire Drawing → Surface Treatment → Diameter Control → Mechanical Testing → Surface Inspection → Coiling → Final Inspection → Packaging

During production, relevant inspection items can include:

• Material grade
• Wire diameter
• Diameter tolerance
• Tensile strength
• Elongation
• Surface condition
• Coil condition
• Packaging condition

For customized requirements, inspection criteria can be agreed according to the customer's technical specification or applicable standard.

Quality Control for Spring Wire

Dimensional Control

Wire diameter and tolerance are important parameters for spring production because they directly affect the geometry of the finished spring.

Mechanical Property Control

Tensile strength and elongation should be evaluated according to the specified diameter, wire condition and applicable standard.

The tensile strength should not be treated as one fixed value for the complete 0.15–12 mm range. Different diameters and specifications may require different mechanical-property ranges.

Surface Inspection

The wire surface can be inspected according to the agreed surface specification, such as bright or soap-coated condition.

Packing Inspection

Spring wire can be supplied in coils, spools or other agreed packaging formats according to the customer's production and transportation requirements.

OEM and Custom Spring Wire

For customized 304H spring wire requirements, customers can provide a technical drawing, finished spring sample or wire specification.

The following information is recommended:

For non-standard spring-wire requirements, the final specification should be confirmed before production.
