Product Introduction

0.8mm 302 Stainless Steel Spring Wire is a cold-drawn stainless steel wire designed for spring manufacturing, precision wire forming and industrial components.

Manufactured from AISI 302 stainless steel, this spring wire features a controlled 0.8mm diameter and is available with bright or soap-coated surface options. The available diameter range is 0.15–12mm, covering fine wire and larger diameter spring wire requirements.

The product can be supplied according to international standards including ASTM, JIS, EN, DIN and equivalent specifications. ISO9001 quality management certification and RoHS compliance documentation can be provided according to project requirements.

AISI 302 is an austenitic stainless steel grade commonly used for spring wire applications. Its cold-working characteristics make it suitable for compression springs, torsion springs, extension springs and other formed-wire components.

For different spring applications, wire grade, diameter, surface condition, tensile strength and forming requirements should be confirmed according to the final component design.

Product Specifications

AISI 302 Stainless Steel Spring Wire

AISI 302 stainless steel is an austenitic stainless steel grade widely used in spring wire production.
