2.2mm 302 Soap-Coated Stainless Steel Spring Wire

Product Introduction

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.

Product Specifications

302 Stainless Steel Spring Wire

AISI 302 stainless steel is a commonly used material grade for stainless steel spring wire.

The material provides a balance of corrosion resistance and cold-work hardening characteristics, making it suitable for spring manufacturing applications where stainless steel material and controlled mechanical properties are required.

For spring production, the final wire specification should be selected according to:

• Spring design
• Required load
• Deflection requirements
• Forming method
• Operating environment
• Required mechanical properties

2.2mm Stainless Steel Spring Wire

The nominal diameter of this product is 2.2mm.

Wire diameter is an important factor affecting spring performance, including spring force, coil dimensions and forming parameters.

When selecting 2.2mm stainless steel spring wire, buyers should consider:

• Wire diameter tolerance
• Spring dimensions
• Coil diameter
• Number of active coils
• Working load
• Spring operating conditions

For customized requirements, customers can provide drawings, specifications or technical requirements for confirmation.

Soap-Coated Surface Stainless Steel Wire

The soap-coated surface provides a suitable surface condition for spring manufacturing and wire forming processes.

Compared with untreated surfaces, the surface condition of spring wire should be selected according to:
