Product Introduction

1.2mm and 1.4mm 302 Soap-Coated Stainless Steel Spring Wire is a cold-drawn stainless steel wire designed for spring manufacturing, screw forming, wire forming and industrial components.

Manufactured from AISI 302 stainless steel, this spring wire is available with a soap-coated surface suitable for different forming processes. The available diameter range is 0.15–12mm, covering fine wire and industrial spring wire requirements.

AISI 302 is an austenitic stainless steel grade commonly used for spring wire applications. Through cold drawing, the wire diameter and mechanical properties can be controlled according to different spring manufacturing requirements.

For customized spring wire applications, buyers should confirm the material grade, wire diameter, surface condition, tensile strength, standard and production requirements before ordering.
