1.5mm 302 Bright Stainless Steel Spring Wire for Precision Forming

Product Introduction

1.5mm 302 Bright Stainless Steel Spring Wire is a cold-drawn stainless steel wire designed for spring manufacturing, wire forming and precision components.

Manufactured from AISI 302 stainless steel, this spring wire is available with a bright surface finish and a diameter range of 0.15–12mm. The 1.5mm diameter is suitable for applications requiring a defined wire size for spring forming and wire-forming processes.

AISI 302 stainless steel is an austenitic grade commonly used for spring wire applications. Its cold-working characteristics allow the wire to achieve mechanical properties suitable for different spring designs and forming requirements.

For specific spring applications, wire grade, diameter, tensile strength, surface condition and applicable standard should be selected according to the spring design, forming process and service conditions.

Product Specifications

AISI 302 Stainless Steel Spring Wire

AISI 302 is an austenitic stainless steel grade widely used for stainless steel spring wire. The material can be cold worked to obtain the mechanical properties required for different spring applications.

When selecting 302 spring wire, buyers should consider more than the nominal diameter. Spring design, working load, deflection, forming method, tensile strength and service environment should all be considered when defining the wire specification.

Bright Surface Stainless Steel Wire

The bright surface provides a clean and uniform appearance for applications where wire surface condition is important.

For automated spring coiling and wire forming, surface condition should be considered together with wire diameter, mechanical properties and forming equipment. The required surface finish can be confirmed according to the customer's production process.

Diameter Range: 0.15–12mm

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

The wide diameter range allows manufacturers to source fine stainless steel wire and larger-diameter spring wire for different production requirements.

For customized orders, the required diameter, material grade, surface condition and mechanical properties can be specified before production.

Applications

Spring Manufacturing

302 stainless steel spring wire can be used for manufacturing:

• Compression Springs

• Extension Springs

• Torsion Springs

• Small Precision Springs

• Industrial Springs

• Stainless Steel Spring Components

The appropriate wire specification should be selected according to spring dimensions, working load, deflection and forming requirements.

Wire Forming

The wire can also be used for various formed-wire components, including:

• Wire Forms

• Clips

• Hooks

• Retaining Components

• Brackets

• Hardware Components

Precision Components

1.5mm stainless steel spring wire can be considered for precision components where controlled wire diameter, stainless steel material and defined mechanical properties are required.

Product Advantages

AISI 302 Stainless Steel

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

1.5mm Nominal Diameter

The 1.5mm diameter provides a defined wire size for spring manufacturing and wire-forming processes.

0.15–12mm Diameter Range

The available diameter range covers fine-wire applications through larger industrial wire requirements.

Bright Surface

The bright surface is suitable for applications where wire appearance and surface condition are important to downstream processing.

Cold-Drawn Manufacturing

Cold drawing is used to control wire diameter and develop the mechanical properties 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 requiring specific standards or mechanical properties, buyers can provide the required material grade, diameter, tensile strength, surface condition and applicable standard for technical confirmation.

Applicable Standards

For stainless steel spring wire applications, specifications can be defined according to applicable international standards such as ASTM, AISI, EN, DIN or JIS.

ASTM A313/A313M is a commonly referenced specification for stainless steel spring wire. When a specific standard is required, the material grade, wire diameter, mechanical requirements and inspection requirements should be confirmed according to the purchase specification.

Packaging and Supply

Stainless steel spring wire can be supplied in coils or spools according to wire diameter, production equipment and customer requirements.

Customized supply specifications can include:

• Material Grade

• Wire Diameter

• Surface Condition

• Tensile Strength

• Coil or Spool Type

• Coil Weight

• Applicable Standard

• Order Quantity

How to Specify 302 Stainless Steel Spring Wire

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

The basic purchasing specification should include:

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

For example:

AISI 302 + 1.5mm + Bright Surface + Required Tensile Strength + ASTM A313 + Required Quantity

Providing these parameters helps suppliers confirm whether the wire condition is suitable for the customer's spring manufacturing or wire-forming process.
