2.3mm 302 Stainless Steel Spring Wire for Spring Manufacturing

TOPONE supplies 2.3mm 302 stainless steel spring wire for spring manufacturing and wire-forming applications, including compression springs, torsion springs and extension springs.

The specified 2.3mm diameter provides a defined wire size for spring manufacturers selecting material according to spring geometry, forming equipment and required working conditions.

AISI 302 stainless steel spring wire is commonly selected for applications where stainless steel material and controlled wire dimensions are required. The appropriate wire condition, surface and mechanical properties should be confirmed according to the spring design and production process.

Product Specifications

Note: Mechanical properties, dimensional tolerance and surface condition should be confirmed according to the required wire condition and applicable product specification.

2.3mm 302 Stainless Steel Spring Wire

Defined 2.3mm Wire Diameter

The 2.3mm diameter is the key specification of this product. Wire diameter directly affects the geometry and mechanical behavior of a finished spring, so it should be evaluated together with the spring's coil diameter, free length, number of coils and required load.

For production inquiries, buyers should provide the required wire diameter and tolerance rather than specifying diameter alone.

302 Stainless Steel Material

AISI 302 is an austenitic stainless steel grade used in stainless steel wire and spring applications.

For spring production, material grade should be considered together with wire condition, diameter and forming requirements. Different processing conditions can result in different mechanical properties, so the material grade alone should not be treated as a complete spring specification.

Applications

Compression Springs

2.3mm 302 stainless steel spring wire can be used for compression spring production where the wire diameter and material condition match the spring design.

Typical selection factors include:

• Spring outside diameter

• Free length

• Number of active coils

• Required spring load

• Working deflection

• Forming equipment

Torsion Springs

For torsion spring production, wire diameter is evaluated together with coil diameter, leg configuration and required torque.

The 2.3mm wire specification can therefore be considered for torsion spring applications where the required geometry and material condition are compatible with the forming process.

Extension Springs

The wire can also be used for extension spring production. Selection should consider the required spring dimensions, load characteristics, hook configuration and forming method.

Wire-Formed Components

In addition to conventional springs, stainless steel spring wire can be processed into selected wire forms, clips and hardware components where the specified diameter and material condition are appropriate.

Spring Wire Selection Guide

When selecting 2.3mm 302 stainless steel spring wire, buyers should consider more than material grade.

This approach helps manufacturers specify wire based on the actual production requirement rather than selecting stainless steel wire only by grade.

Quality and Technical Information

For industrial spring wire, product quality should be evaluated using measurable specifications.

Important inspection items can include:

• Material grade

• Wire diameter

• Diameter tolerance

• Tensile strength

• Surface condition

• Wire condition

• Coil or spool condition

The applicable inspection requirements and documentation can be confirmed according to the order specification.

Packaging and Supply

2.3mm 302 stainless steel spring wire can be supplied in coil or spool form.

Packaging selection can be discussed according to coil weight, spool dimensions, transportation requirements and the customer's spring-forming equipment.

For automated production lines, buyers should confirm the required unwinding and packaging format before placing an order.

FAQ
