0.7mm AISI 302 Stainless Steel Spring Wire with Soap-Coated Surface
Product Introduction
TOPONE 0.7mm AISI 302 stainless steel spring wire is designed for spring manufacturers requiring a defined wire diameter, spring-tempered condition and lubricated surface for wire forming.
Made from AISI 302 stainless steel, this wire has a nominal diameter of 0.7mm and a soap-coated surface. The listed tensile strength for this specification is 1850–2150 N/mm². Final mechanical properties should be confirmed against the order specification and inspection documentation.
The soap-coated surface can be considered for spring coiling and other wire-forming processes where surface lubrication is required. The suitability of the wire depends on spring design, forming equipment, dimensional tolerance and operating conditions.
TOPONE also offers stainless steel wire in diameters from 0.15–12mm, subject to grade, mechanical condition and product specification.

Key Features of 0.7mm 302 Spring Wire
Defined Diameter for Spring Production
The nominal 0.7mm diameter provides a specific starting size for spring designs that require fine stainless steel wire. The required diameter tolerance should be confirmed according to the spring drawing and production equipment.
Soap-Coated Surface for Wire Forming
Soap coating provides a lubricated surface that may be suitable for spring coiling and other wire-forming operations. The coating should be matched to the tooling, feeding system and downstream process.
Spring-Tempered Mechanical Condition
Spring-tempered wire is used for applications requiring defined mechanical properties. The listed tensile strength of 1850–2150 N/mm² applies to this product specification and should not be assumed for other diameters or delivery conditions.
AISI 302 Stainless Steel
AISI 302 is an austenitic stainless steel grade commonly used for cold-worked wire and spring applications. The appropriate wire condition should be selected according to the required spring load, deflection, forming process and service environment.
Applications
Compression Springs
The wire may be used for compression springs when the diameter and mechanical properties meet the design requirements, including spring rate, load and working deflection.
Extension Springs
For extension springs, consider the required load, extension, end configuration and operating cycle when selecting the wire specification.
Torsion Springs
For torsion spring applications, wire diameter, material condition and spring geometry should be evaluated together to meet the required torque and operating performance.
Precision Wire-Formed Components
The wire may also be considered for small formed-wire parts where 302 stainless steel and the specified mechanical condition are suitable.
