Product Specification

1.6mm 302 Stainless Steel Spring Wire for Industrial Spring Making

Product Introduction

1.6mm 302 Stainless Steel Spring Wire is a round stainless steel wire designed for industrial spring manufacturing, wire forming and mechanical components.

Made from AISI 302 stainless steel, this wire is available in a 1.6mm nominal diameter and can be supplied with bright or soap-coated surface conditions according to the forming process and application requirements.

The wider stainless steel spring wire range is 0.15–12mm, allowing manufacturers to select different wire diameters for fine springs, general spring components and larger industrial applications.

For spring manufacturing, wire diameter should be selected together with spring geometry, working load, deflection, mechanical condition and forming equipment.

Product Specifications

Note: Final tensile strength, dimensional tolerance and mechanical condition should be confirmed according to the selected wire condition, applicable standard and purchase specification.

AISI 302 Stainless Steel for Spring Manufacturing

AISI 302 is an austenitic stainless steel grade commonly used for stainless steel wire and spring applications.

For industrial spring manufacturing, the material grade should be considered together with wire diameter and mechanical condition.

The appropriate specification depends on factors such as:

• Wire diameter

• Tensile strength

• Spring geometry

• Working load

• Working deflection

• Forming method

• Surface condition

• Service environment

This specification-based approach helps manufacturers select spring wire according to the actual component and production requirements.

1.6mm Diameter for Industrial Springs

The 1.6mm nominal diameter provides a defined wire size for industrial spring and wire-forming applications.

Wire diameter directly affects spring geometry, stiffness and the space required by the finished component. Therefore, the 1.6mm specification should be evaluated together with the complete spring design.

Before selecting the wire, manufacturers should confirm:

Spring Diameter

The required coil diameter should be compatible with the selected 1.6mm wire diameter and forming equipment.

Working Load

The required spring force should be considered when selecting wire diameter and mechanical condition.

Working Deflection

The expected deflection should be considered together with the spring geometry and wire specification.

Number of Coils

The number of active coils affects the finished spring characteristics and should be considered during material selection.

Bright and Soap-Coated Surface Options

Bright Surface

The bright surface provides a clean metallic appearance and a defined surface condition for spring and wire-forming applications.

It can be selected when the forming equipment and downstream process are suitable for a bright wire surface.

Soap-Coated Surface

Soap-coated wire can be considered for forming processes where a lubricated wire surface is required.

The appropriate surface condition should be selected according to:

• Wire feeding system

• Forming equipment

• Tooling

• Lubrication requirements

• Forming speed

• Subsequent processing

Bright and soap-coated surfaces should therefore be selected according to the actual manufacturing process.

Hard and Soft Wire Conditions

The product can be supplied in different wire conditions according to application requirements.

Hard Condition

A hard wire condition can be considered for applications requiring a higher cold-worked mechanical condition.

The exact tensile strength should be confirmed according to the selected diameter, production condition and applicable standard.

Soft Condition

A softer condition can be considered where the forming process requires greater workability before or during subsequent processing.

The appropriate condition should be determined based on the customer's forming equipment and finished component requirements.

0.15–12mm Stainless Steel Spring Wire Range

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

The 1.6mm specification is one option within this product range.

These are general application references. The final diameter should be determined according to the finished spring drawing, required load and forming process.

Applications

Compression Springs

1.6mm 302 stainless steel spring wire can be used for compression spring production when the wire condition and mechanical properties match the required spring design.

Important parameters include:

• Spring diameter

• Free length

• Working load

• Working deflection

• Number of active coils

Extension Springs

The wire can also be evaluated for extension spring manufacturing.

Important considerations include:

• Required extension force

• Hook design

• Spring length

• Wire diameter

• Forming method

Torsion Springs

For torsion springs, wire diameter, coil geometry, working angle and required torque should be considered together.

The 1.6mm specification can be selected when it matches the required spring design parameters.

Industrial Wire Forms

The wire can also be considered for formed-wire components such as:

• Clips

• Hooks

• Retaining components

• Brackets

• Wire forms

• Industrial hardware

• AISI

• EN

• DIN

• JIS

• GB

• Equivalent customer specifications

The exact standard, diameter tolerance, tensile strength, wire condition, surface condition and inspection requirements should be confirmed before production.

How to Select 1.6mm 302 Stainless Steel Spring Wire

Selecting spring wire should start from the finished spring requirements rather than diameter alone.

Step 1: Define the Spring Type

Determine whether the component is a compression spring, extension spring, torsion spring or another wire-forming component.

Step 2: Confirm the Wire Diameter

Confirm whether 1.6mm matches the required spring geometry and forming equipment.

Step 3: Select the Wire Condition

Determine whether a hard or soft condition is appropriate for the forming process and required mechanical properties.

Step 4: Select the Surface

Choose bright or soap-coated surface according to the wire feeding system, forming equipment and lubrication requirements.

Step 5: Confirm the Standard

Specify the required ASTM, EN, DIN, JIS or other applicable standard.

Step 6: Confirm Packaging

For automated spring production, confirm coil weight, spool dimensions and unwinding requirements before ordering.
