Product Specification

2.0mm 302 Stainless Steel Spring Wire with 1650–1900 N/mm² Tensile Strength

Product Introduction

2.0mm 302 Stainless Steel Spring Wire is a round stainless steel spring wire designed for spring manufacturing and industrial wire-forming applications.

This product has a nominal wire diameter of 2.0 mm and a specified tensile strength range of 1650–1900 N/mm². The combination of Type 302 stainless steel, defined wire diameter and specified tensile strength provides a clear material specification for spring manufacturers.

The wire is suitable for applications including compression springs, torsion springs and extension springs. Final spring performance depends on the wire specification, spring geometry, forming process, working load and operating environment.

Product Specifications

Note: The tensile strength range of 1650–1900 N/mm² applies to the specified product condition. Dimensional tolerance, surface condition, applicable standard and other technical requirements should be confirmed according to the purchase specification.

Key Features

1. Defined 2.0mm Wire Diameter

The nominal diameter of 2.0 mm provides a defined wire size for spring manufacturing.

Wire diameter is an important parameter in spring design because it affects the spring's geometry, forming conditions and load characteristics. For production applications, the required diameter tolerance should be confirmed together with the spring design.

2. Tensile Strength of 1650–1900 N/mm²

This spring wire is specified with a tensile strength range of 1650–1900 N/mm².

Providing a defined tensile strength range gives spring manufacturers a measurable mechanical specification when selecting wire for forming and spring production.

The required tensile strength should be matched with the intended spring type, forming process and final spring requirements rather than considered separately from wire diameter and spring geometry.

3. 302 Stainless Steel Grade

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

The material can be cold worked to achieve the required mechanical condition. The final properties of the wire depend on material grade, processing condition, diameter and specified mechanical requirements.

4. Suitable for Different Spring Types

The 2.0mm 302 stainless steel spring wire can be used for manufacturing:

• Compression springs

• Torsion springs

• Extension springs

• Industrial mechanical springs

• Wire-formed spring components

• Stainless steel spring parts

The appropriate wire specification should be selected according to the design and operating requirements of the finished component.

Applications

Compression Springs

The wire can be formed into compression springs used in mechanical assemblies and industrial equipment.

For compression spring applications, wire diameter, spring diameter, coil geometry, working load and deflection should be considered together.

Torsion Springs

2.0mm 302 stainless steel spring wire can be used for torsion springs that operate through rotational or twisting movement.

The required tensile strength and wire diameter should be evaluated together with the torque requirement, spring geometry and forming process.

Extension Springs

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

For this application, the spring wire should be selected according to the required load, extension range, coil dimensions and end configuration.

Industrial Wire-Formed Components

In addition to conventional springs, 302 stainless steel spring wire can be used for various industrial wire-formed components where a defined stainless steel grade, diameter and mechanical condition are required.

Technical Considerations Before Ordering

When selecting 2.0mm 302 stainless steel spring wire, buyers should confirm the complete technical specification.

Important parameters include:

• Material grade

• Wire diameter

• Diameter 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

For applications with specific mechanical requirements, the tensile strength range should be confirmed together with the wire diameter and spring design.

Quality and Specification Control

For industrial spring wire, measurable product specifications are important for material selection and production control.

Relevant inspection and quality-control items may include:

• Chemical composition

• Stainless steel grade

• Wire diameter

• Dimensional tolerance

• Tensile strength

• Surface condition

• Mechanical condition

• Applicable spring wire tests

For this product, the specified tensile strength range of 1650–1900 N/mm² provides a clear mechanical parameter for technical evaluation.

Where a specific material or spring wire standard is required, the applicable requirements should be confirmed against the actual purchase specification.

How to Select Stainless Steel Spring Wire

Spring wire selection should consider several parameters together:

Material Grade → Wire Diameter → Tensile Strength → Surface Condition → Spring Type → Spring Geometry → Working Conditions

For this product, the key specifications are:

• Material: 302 stainless steel

• Diameter: 2.0 mm

• Tensile Strength: 1650–1900 N/mm²

The final selection should then be evaluated according to the specific spring design and manufacturing process.

Why Choose 2.0mm 302 Stainless Steel Spring Wire?

This product provides a defined combination of 302 stainless steel, 2.0 mm diameter and 1650–1900 N/mm² tensile strength for industrial spring manufacturing.

Compared with a product description based only on material and diameter, specifying the tensile strength range provides buyers with an additional measurable parameter for technical selection.

The wire is suitable for compression, torsion, extension and other wire-formed spring applications where the specified material and mechanical condition meet the requirements of the finished component.
