2.6mm 302 SCO Soap-Coated Bright Stainless Steel Spring Wire

Product Introduction

2.6mm 302 SCO Soap-Coated Bright Stainless Steel Spring Wire is a cold-drawn stainless steel wire designed for spring manufacturing, wire forming and other applications requiring a defined wire diameter and controlled surface condition.

Made from AISI 302 stainless steel, this spring wire is available with a bright or soap-coated surface. The nominal diameter of this product is 2.6mm, with an available diameter range of 0.15–12mm for different spring and wire-forming requirements.

AISI 302 is an austenitic stainless steel grade commonly used for spring wire. Its cold-working characteristics make it suitable for applications where the wire needs to be formed into springs or other wire components.

For spring production, the appropriate wire condition should be selected according to spring geometry, working load, forming process, required mechanical properties and service environment.

Product Specifications

302 Stainless Steel Spring Wire

AISI 302 stainless steel is a commonly used austenitic grade for stainless steel spring wire. The material can be cold worked to obtain mechanical properties suitable for different spring manufacturing requirements.

For a 2.6mm spring wire, the final specification should not be determined by diameter alone. Spring geometry, load requirements, deflection, forming equipment and required mechanical properties should also be considered when selecting the wire condition.

Soap-Coated and Bright Surface Options

The 2.6mm 302 spring wire is available with either a bright surface or soap-coated surface.

Bright Surface

The bright surface provides a clean metallic appearance and can be selected for applications where surface condition and appearance are important.

Soap-Coated Surface

Soap coating can be considered for wire-forming and spring-making processes where the surface condition needs to be matched with the customer's forming equipment and production process.

The appropriate surface should be selected according to the forming method, tooling and downstream processing requirements.

0.15–12mm Diameter Range

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

The 2.6mm diameter is suitable for spring and wire-forming applications requiring a medium wire diameter. Other diameters within the 0.15–12mm range can also be specified according to the customer's spring design and production requirements.

For customized orders, buyers can provide the required diameter, material grade, surface condition, tensile strength and applicable standard for technical confirmation.

Applications

Compression Springs

2.6mm 302 stainless steel spring wire can be used for compression spring production when the wire condition and mechanical properties match the spring design.

Typical applications include industrial equipment, hardware components and stainless steel spring assemblies.

Extension Springs

The wire can be processed into extension springs where the specified wire diameter, tensile properties and forming requirements are suitable for the spring design.

Torsion Springs

For torsion spring applications, wire selection should consider the spring geometry, forming process, working load and required mechanical properties.

Wire Forms and Clips

The 2.6mm wire can also be processed into:

• Wire Forms

• Clips

• Hooks

• Retaining Components

• Brackets

• Fasteners

• Hardware Components

Product Advantages

AISI 302 Stainless Steel

AISI 302 provides a commonly used stainless steel material option for spring manufacturing and cold wire forming.

2.6mm Defined Diameter

The 2.6mm nominal diameter provides a specific starting point for spring design and wire-forming applications.

Bright and Soap-Coated Options

Two surface options are available to accommodate different downstream forming and processing requirements.

0.15–12mm Diameter Availability

The wider diameter range allows buyers to source different sizes of stainless steel spring wire from the same product range.

Cold-Drawn Manufacturing

Cold drawing is used to control the wire diameter and develop the mechanical condition required for spring-wire applications.

Quality Control and Inspection

Quality control for stainless steel spring wire can include:

• Chemical Composition Verification

• Wire Diameter Inspection

• Surface Inspection

• Tensile Strength Testing

• Dimensional Inspection

• Coil or Spool Weight Verification

• Material Test Certificate

• Inspection Report According to Order Requirements

For orders with specific technical requirements, buyers can provide the required grade, diameter, tensile strength, surface condition and applicable standard before production.

Applicable Standards

Stainless steel spring wire specifications can be defined according to applicable international standards such as AISI, ASTM, EN, DIN and JIS.

For spring-wire applications, the applicable standard should be confirmed according to the customer's required material grade, wire diameter, mechanical properties and inspection requirements.

Packaging and Supply

The 2.6mm 302 stainless steel spring wire can be supplied in coils or spools according to the wire diameter, production equipment and customer requirements.

Available packaging specifications can be discussed according to:

• Coil or Spool Type

• Coil Weight

• Wire Diameter

• Surface Condition

• Order Quantity

• Customer Handling Requirements

How to Specify 302 Spring Wire

When purchasing 302 stainless steel spring wire, it is recommended to provide complete technical information rather than only the wire diameter.

A typical purchasing specification includes:

Grade + Diameter + Surface + Tensile Strength / Condition + Standard + Quantity

For example:

AISI 302 + 2.6mm + Soap Coated + Required Tensile Strength + Applicable Standard + Required Quantity

Providing these parameters helps the supplier confirm the appropriate wire condition for the customer's spring-making or wire-forming process.
