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

Product Introduction

2.0mm 302 Stainless Steel Spring Wire is an austenitic stainless steel wire designed for spring manufacturing and other formed-wire applications where controlled mechanical properties and corrosion resistance are required.

This product is manufactured from AISI 302 stainless steel and supplied in a 2.0 mm nominal diameter with a specified tensile strength range of 1650–1900 N/mm². The combination of 302 stainless steel and controlled tensile strength makes the wire suitable for compression springs, extension springs, torsion springs, and other mechanical spring components.

For spring manufacturers, selecting the correct wire diameter, tensile strength, surface condition, and material grade is important because these parameters directly affect spring forming, load performance, and the final application requirements.

Why Choose 302 Stainless Steel Spring Wire?

AISI 302 Stainless Steel for Spring Applications

AISI 302 is an austenitic stainless steel grade commonly used for stainless steel spring wire. Its combination of mechanical properties and corrosion resistance makes it suitable for spring components used in industrial and general mechanical applications.

The material grade should be selected according to the spring design, working environment, forming process, and required mechanical properties rather than by diameter alone.

Controlled 2.0mm Diameter

A nominal diameter of 2.0 mm provides a defined starting specification for spring manufacturers. Wire diameter is one of the key parameters in spring design because it affects the geometry and mechanical behavior of the finished spring.

For production orders, dimensional tolerance should be confirmed according to the applicable specification and the customer's spring-forming requirements.

Specified Tensile Strength: 1650–1900 N/mm²

The specified tensile strength range of 1650–1900 N/mm² provides a clear mechanical-property target for this product.

For spring production, tensile strength should be considered together with wire diameter, spring index, forming method, working load, and required fatigue performance. A higher tensile strength should not automatically be considered better because the appropriate range depends on the finished spring design and manufacturing process.

Applications

Compression Springs

2.0mm 302 stainless steel spring wire can be used for compression springs designed to resist compressive loads.

Typical applications include mechanical assemblies, industrial equipment, electrical components, and general-purpose spring mechanisms.

Extension Springs

The wire can also be processed into extension springs where the spring is designed to operate under tensile loading.

Torsion Springs

For torsion spring production, wire diameter and tensile strength need to be evaluated together with coil diameter, leg geometry, forming conditions, and required operating torque.

Precision and General Mechanical Springs

302 stainless steel spring wire is also suitable for various formed-wire and spring components where stainless steel material is preferred for the operating environment.

Technical Considerations for Selecting 2.0mm Spring Wire

When purchasing stainless steel spring wire, buyers should confirm more than the material grade and diameter.

The following specifications should be considered:

• Stainless steel grade

• Nominal wire diameter

• Diameter tolerance

• Tensile strength range

• Surface condition

• Spring temper or cold-drawn condition

• Required spring-forming process

• Coil or spool packaging

• Applicable technical standard

• End-use working environment

For spring manufacturers, providing the complete specification helps the wire supplier select an appropriate production condition and mechanical-property range.

Quality and Production Considerations

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

Important quality-control items can include chemical composition, wire diameter and tolerance, tensile strength, surface condition, dimensional uniformity, and applicable mechanical tests.

Where required, production can be discussed according to relevant stainless steel spring wire specifications such as ASTM A313/A313M or other customer-specified standards.

Why TOPONE Wire?

TOPONE Wire focuses on stainless steel wire products for industrial and manufacturing applications, including stainless steel spring wire, annealed wire, EPQ wire, and other customized wire products.

For 2.0mm 302 stainless steel spring wire, customers can confirm the required grade, diameter, tensile strength, surface condition, quantity, packaging, and applicable standard before production.

This specification-based approach helps match the wire to the customer's spring manufacturing process instead of selecting the material based only on product name or diameter.
