Product Specification

5mm 302 Stainless Steel Spring Wire for JIS Springs

Product Introduction

5mm 302 stainless steel spring wire is designed for manufacturing compression springs, torsion springs, and extension springs.

Made from AISI 302 stainless steel, the wire is suitable for spring applications that require stainless steel material properties together with controlled forming performance. The product can be supplied according to JIS-related requirements and customer specifications.

The 5mm diameter is suitable for larger spring components and industrial wire-forming applications.

Product Specifications

AISI 302 Stainless Steel Spring Wire

AISI 302 stainless steel is widely used for stainless steel spring and wire-forming applications.

For spring manufacturing, the appropriate wire condition should be selected according to the spring design, forming process, working load, and service environment.

For projects requiring JIS specifications, the required standard, dimensional tolerance, mechanical properties, and surface condition should be confirmed before production.

5mm Wire for Compression, Torsion and Extension Springs

Compression Springs

5mm 302 stainless steel spring wire can be used for compression springs in mechanical equipment, industrial components, hardware, and other spring assemblies.

Torsion Springs

For torsion springs, wire diameter and material condition should be selected according to the required torque, coil diameter, number of turns, and forming method.

Extension Springs

302 stainless steel spring wire can also be used for extension springs and other components subjected to tensile loading during operation.
