2.2mm 302 Soap-Coated Stainless Steel Spring Wire is a cold-drawn stainless steel wire designed for spring manufacturing, wire forming and precision industrial components.
Manufactured from AISI 302 stainless steel, this spring wire features a soap-coated surface suitable for downstream spring coiling and wire-forming processes. The nominal diameter of this product is 2.2mm, with an available diameter range of 0.15–12mm to meet different spring production requirements.
AISI 302 stainless steel is an austenitic stainless steel grade widely used for spring wire applications. Its cold-working characteristics allow manufacturers to achieve the required mechanical properties for compression springs, torsion springs, extension springs and other formed-wire components.
For different spring designs, wire selection should consider material grade, diameter, tensile strength, surface condition, forming process and working environment.
