0.2mm 302 Soap-Coated Stainless Steel Spring Wire

Product Introduction

0.2mm 302 Soap-Coated Stainless Steel Spring Wire is a fine stainless steel spring wire designed for small springs, precision wire forming and components requiring a fine wire diameter.

Manufactured from AISI 302 stainless steel, this wire has a nominal diameter of 0.2mm and is available in a wider diameter range of 0.15–12mm. The soap-coated surface can be selected according to the requirements of downstream spring coiling and wire-forming processes.

AISI 302 is an austenitic stainless steel grade commonly used for spring wire. Its cold-working characteristics make it suitable for applications where stainless steel wire needs to be formed into springs or other fine wire components.

For fine-wire applications, wire diameter, material grade, surface condition and mechanical properties should be selected according to the spring design, forming equipment and service requirements.

Product Specifications

302 Stainless Steel Spring Wire

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

For spring manufacturing, the final mechanical condition depends on factors such as wire diameter, cold working and specified tensile properties. Therefore, selecting fine spring wire should consider the complete spring design rather than diameter alone.

The 0.2mm diameter is particularly suited to applications where a fine wire size is required for small springs and precision formed-wire components.

0.2mm Fine Stainless Steel Spring Wire

With a nominal diameter of only 0.2mm, this product is designed for fine-wire applications where a smaller wire diameter is required.

Fine spring wire selection should take into account:

• Wire Diameter

• Spring Geometry

• Required Tensile Strength

• Forming Method

• Coil Diameter

• Working Load

• Spring Deflection

• Surface Condition

For automated spring coiling or precision wire forming, the wire specification should be matched with the production equipment and tooling.

Soap-Coated Surface

The soap-coated surface provides a defined surface condition for downstream wire forming and spring-making processes.

Surface requirements can vary depending on the customer's equipment, tooling and forming method. Therefore, the appropriate surface condition should be confirmed before production.

For applications requiring a bright surface rather than soap coating, the surface specification can be discussed according to the customer's production requirements.

Diameter Range: 0.15–12mm

TOPONE supplies stainless steel spring wire in diameters from 0.15mm to 12mm.

The range covers fine stainless steel wire as well as larger-diameter spring wire for different industrial applications.

The 0.2mm size is suitable for fine spring and precision wire-forming applications, while other diameters can be selected according to the customer's spring design and production requirements.

Quality Control and Inspection

Quality control for stainless steel spring wire can include:

• Chemical Composition Verification

• Wire Diameter Inspection

• Surface Inspection

• Tensile Strength Testing

• Dimensional Inspection

• Coil or Spool Weight Verification

• Material Test Certificate

• Inspection Report According to Order Requirements

For customized fine-wire orders, buyers can provide the required grade, diameter, tensile strength, surface condition and applicable standard for technical confirmation.

Applicable Standards

Stainless steel spring wire can be supplied according to applicable international standards specified by the customer.

ASTM A313/A313M is a standard specification covering austenitic and age-hardenable stainless steel round spring wire intended especially for spring manufacturing. The specification addresses chemical composition, tensile strength and mechanical tests including wrap, uniformity and bend testing.

If a specific ASTM, JIS, EN or DIN requirement applies to the order, the exact standard and required mechanical properties should be confirmed before production.

Packaging and Supply

0.2mm 302 stainless steel spring wire can be supplied in coils or spools according to the wire diameter, production equipment and customer requirements.

Packaging requirements can be specified according to:

• Coil or Spool Type

• Coil Weight

• Wire Diameter

• Surface Condition

• Order Quantity

• Customer Handling Requirements

How to Specify 0.2mm Stainless Steel Spring Wire

For accurate purchasing and technical confirmation, buyers should provide the complete wire specification.

A typical purchasing specification includes:

Grade + Diameter + Surface + Tensile Strength / Condition + Standard + Quantity

For example:

AISI 302 + 0.2mm + Soap Coated + Required Tensile Strength + Applicable Standard + Required Quantity

Providing these parameters helps the supplier confirm the appropriate wire condition for fine spring manufacturing and precision wire forming.
