Product Specification

2.2mm 302 Soap Coated Stainless Steel Spring Wire

Product Introduction

2.2mm 302 soap coated stainless steel spring wire is designed for spring manufacturing and wire forming applications where a controlled surface condition is required during forming.

Made from AISI 302 stainless steel, this spring wire combines the material characteristics of 302 stainless steel with a soap-coated surface suitable for spring production processes.

The 2.2mm diameter is suitable for medium-to-large spring components, while other diameters from 0.15–12mm can be selected according to the application.

Product Specifications

AISI 302 Stainless Steel Spring Wire

AISI 302 is an austenitic stainless steel grade commonly used for spring and wire-forming applications.

For spring production, the suitable material condition should be selected according to the spring design, forming method, required mechanical properties, and service conditions.

The 2.2mm diameter provides an option for spring components requiring a larger wire size than fine spring wire.

Why Use Soap Coated Spring Wire?

A soap-coated surface can be selected for spring manufacturing processes where surface condition and forming behavior are important.

The appropriate coating condition should be confirmed according to the customer's spring forming equipment, tooling, and production process.

Applications

Compression Springs

2.2mm 302 stainless steel spring wire can be used for compression spring manufacturing in mechanical and industrial components.

Torsion Springs

The wire can also be selected for torsion spring production. Wire diameter and material condition should be matched with the required torque and spring geometry.

Extension Springs

302 stainless steel spring wire is suitable for extension spring applications where the spring is subjected to tensile loading.

Wire Forms

The material can also be considered for stainless steel wire-forming components where the required diameter and material condition are suitable.
