2.0mm 302 Stainless Steel Spring Wire – Hard for Compression, Torsion and Extension Springs

Product Introduction

2.0mm 302 Stainless Steel Spring Wire is a round stainless steel spring wire designed for compression, torsion and extension spring manufacturing.

With a nominal diameter of 2.0 mm, this wire is suitable for spring components requiring a defined medium wire size. The 302 stainless steel grade is commonly used for spring wire applications where stainless steel material characteristics and cold-worked mechanical properties are required.

The hard condition provides a defined mechanical condition for spring forming and wire processing. The appropriate wire condition should be selected according to the spring design, forming method, required load and operating environment.

Product Specifications

Note: Tensile strength, dimensional tolerance, surface condition and other mechanical requirements should be confirmed according to the specific production specification or purchase order.

Key Features of 2.0mm 302 Stainless Steel Spring Wire

1. 2.0mm Defined Wire Diameter

The nominal 2.0 mm diameter provides a defined wire size for spring manufacturing and wire-forming applications.

For spring production, wire diameter is an important design parameter because it affects spring geometry, forming conditions, load characteristics and the final dimensions of the spring.

2. 302 Stainless Steel Material

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

The material can be cold worked to achieve the mechanical condition required for spring manufacturing. The actual performance of the finished spring depends on the wire condition, spring geometry, manufacturing process and service conditions.

3. Hard Mechanical Condition

This product is supplied in a hard condition, which refers to the cold-worked state of the spring wire.

The mechanical condition should be matched with the requirements of the spring-forming process. For applications with specific load or fatigue requirements, tensile strength and other mechanical properties should be confirmed before production.

4. Suitable for Multiple Spring Types

2.0mm 302 stainless steel spring wire can be used for different spring configurations, including:

• Compression springs

• Torsion springs

• Extension springs

• Industrial mechanical springs

• Wire-formed spring components

• General-purpose stainless steel spring parts

The final wire selection should be based on the actual spring design and operating conditions.

Applications

Compression Springs

The 2.0mm spring wire can be formed into compression springs designed to resist compressive loads in mechanical assemblies and industrial equipment.

Wire diameter, spring diameter, coil pitch, active coils and working load should be considered together during spring design.

Torsion Springs

302 stainless steel spring wire can also be used for torsion springs that operate through rotational or twisting movement.

The wire condition and diameter should be selected according to the required torque, spring geometry and forming process.

Extension Springs

The wire can be used for extension springs designed for tensile loading.

For extension spring production, the wire specification should be evaluated together with the required load, extension range, coil geometry and end configuration.

Industrial Spring Components

2.0mm 302 stainless steel spring wire is suitable for various mechanical and industrial spring components where a defined stainless steel wire specification is required.

Technical Considerations Before Ordering

Before purchasing 2.0mm stainless steel spring wire, buyers should confirm the complete technical specification rather than selecting the product only by material and diameter.

Important parameters include:

• Material grade

• Wire diameter

• Dimensional tolerance

• Tensile strength

• Mechanical condition

• Surface condition

• Applicable standard

• Spring type

• Spring diameter

• Coil geometry

• Working load

• Working deflection

• Operating temperature

• Service environment

• Forming and coiling requirements

These parameters help determine whether the selected wire is suitable for the intended spring manufacturing process.

Quality and Specification Control

For industrial spring wire, quality should be evaluated using measurable specifications.

Typical inspection points may include:

• Chemical composition

• Material grade

• Wire diameter

• Dimensional tolerance

• Tensile strength

• Mechanical condition

• Surface quality

• Applicable spring wire tests

For applications requiring a specific material or spring wire standard, the applicable requirements should be confirmed against the actual purchase specification.

How to Select 2.0mm Stainless Steel Spring Wire

Selecting spring wire involves more than choosing a stainless steel grade.

A practical selection process includes:

Material Grade → Wire Diameter → Mechanical Condition → Tensile Strength → Surface Condition → Spring Design → Operating Environment

For this product, the key starting specifications are 302 stainless steel, 2.0mm diameter and hard condition.

The final suitability should then be evaluated according to the spring type, working load, spring geometry, forming process and service environment.

Why Choose 2.0mm 302 Stainless Steel Spring Wire?

2.0mm 302 stainless steel spring wire combines a defined 2.0 mm wire diameter, Type 302 stainless steel grade and hard mechanical condition for spring manufacturing applications.

It is suitable for manufacturers producing compression, torsion, extension and other wire-formed spring components.

For B2B purchasing, confirming the complete material, dimensional, mechanical and application requirements before production helps ensure that the selected spring wire matches the intended manufacturing process.
