Product Specification

0.85mm 302 Stainless Steel Spring Wire for Compression, Torsion and Extension Springs

Product Introduction

0.85mm 302 Stainless Steel Spring Wire is an austenitic stainless steel spring wire designed for the production of compression, torsion and extension springs.

With a nominal diameter of 0.85 mm, this spring wire is suitable for spring components requiring a defined fine wire size. AISI 302 stainless steel is commonly used for spring wire applications where stainless steel properties and cold-worked spring characteristics are required.

For spring manufacturing, wire diameter, material grade, tensile strength, surface condition and forming requirements should be considered together. These parameters affect the forming process and the mechanical behavior of the finished spring.

This 0.85mm 302 stainless steel spring wire is suitable for industrial spring manufacturers and wire-forming applications requiring a defined stainless steel spring wire specification.

Product Specifications

Note: Mechanical properties, dimensional tolerance, surface condition and applicable standards should be confirmed according to the specific production specification or purchase order.

Key Features of 302 Stainless Steel Spring Wire

1. Suitable for Spring Manufacturing

AISI 302 stainless steel is widely used for spring wire applications. Its cold-working characteristics make it suitable for producing wire with the mechanical properties required for various spring components.

The final spring performance depends on factors including wire diameter, tensile strength, spring design, forming process and operating conditions.

2. 0.85mm Controlled Wire Diameter

The 0.85 mm diameter is suitable for spring designs requiring a relatively fine wire size.

For spring manufacturing, maintaining the specified wire diameter is important because wire diameter directly affects spring geometry, forming conditions and the mechanical response of the finished spring.

3. Multiple Spring Applications

0.85mm 302 stainless steel spring wire can be used for producing:

• Compression springs

• Torsion springs

• Extension springs

• Small precision springs

• General industrial springs

• Wire-formed spring components

The appropriate wire condition should be selected according to the spring design, working load, deflection, forming method and service environment.

4. Stainless Steel Material

Type 302 is an austenitic stainless steel grade commonly used in stainless steel spring wire applications.

It can be considered for spring components where stainless steel material characteristics are required together with the mechanical properties obtained through cold working.

Material selection should always be evaluated according to the actual operating environment, especially for applications involving corrosive media or chloride exposure.

Applications

Compression Springs

0.85mm 302 stainless steel spring wire can be formed into compression springs designed to resist compressive loads in mechanical assemblies, equipment and industrial components.

Torsion Springs

The wire can be used for torsion spring production where the spring operates through twisting and rotational movement.

Extension Springs

302 stainless steel spring wire can also be formed into extension springs designed for tensile loading, subject to the required spring geometry and mechanical specifications.

Precision and Small Spring Components

The 0.85mm diameter is suitable for applications requiring relatively fine spring wire, including small mechanical components, equipment assemblies and precision spring parts.

Technical Considerations Before Ordering

When selecting stainless steel spring wire, material grade and diameter are only part of the specification.

Buyers should also consider:

• Stainless steel grade

• Wire diameter and tolerance

• Tensile strength or spring temper

• Surface condition

• Applicable material standard

• Spring type

• Forming method

• Required coil geometry

• Working load and deflection

• Operating temperature

• Corrosive or chloride exposure

• Coil and packaging requirements

Matching these parameters with the actual spring design helps ensure that the selected wire is suitable for the intended manufacturing process.

Quality and Specification Control

For stainless steel spring wire, product quality should be evaluated through measurable specifications rather than general claims.

Important inspection items may include:

• Chemical composition

• Wire diameter

• Dimensional tolerance

• Surface condition

• Tensile strength

• Spring wire mechanical properties

• Relevant material and spring wire tests

Where ASTM A313/A313M is specified, the applicable material grade, mechanical condition and testing requirements should be confirmed according to the actual purchase specification.

Why Choose 302 Stainless Steel Spring Wire?

The selection of spring wire should be based on the relationship between material grade, wire diameter, mechanical condition, spring design and operating environment.

The 0.85mm 302 stainless steel spring wire is designed for applications requiring a defined stainless steel spring wire size for compression, torsion, extension and other wire-formed spring components.

For technical requirements, buyers should confirm the required grade, diameter, tensile strength, surface condition, tolerance and applicable standard before production.
