Custom 1.8mm 302 Stainless Steel Spring Wire With SGS Certification And Bright Surface

Custom 1.8mm 302 Stainless Steel Spring Wire

TOPONE custom 1.8mm 302 stainless steel spring wire is designed for spring manufacturing and formed wire applications where material grade, wire diameter, surface condition, and spring design requirements need to be clearly defined.

This product uses 302 stainless steel with a 1.8 mm wire diameter and bright surface. The wire can be used as raw material for different spring components, including compression springs, torsion springs, extension springs, and other formed spring parts.

For customized spring wire requirements, the appropriate specification should be evaluated according to the wire diameter, spring type, coil dimensions, working load, deflection, operating environment, and required material condition. SGS certification is available according to the applicable product and inspection requirements.

Technical Specifications

Material Characteristics

302 Stainless Steel

302 stainless steel is an austenitic stainless steel grade commonly used for wire and spring applications. Grade selection should be based on the required spring design, mechanical properties, forming process, and operating environment.

1.8 mm Wire Diameter

The specified wire diameter is 1.8 mm. Wire diameter is an important parameter in spring design because it affects the geometry, load characteristics, and deformation behavior of the finished spring.

For customized spring production, the 1.8 mm wire should be evaluated together with coil diameter, free length, number of coils, working deflection, and required load.

Bright Surface

The product is supplied with a bright surface. Surface condition should be considered together with the spring forming process, lubrication requirements, and any subsequent surface treatment.

Applications

Compression Springs

302 stainless steel spring wire can be formed into compression springs designed to resist compressive loads. Typical applications include mechanical assemblies, industrial equipment, switches, and hardware components.

Torsion Springs

Torsion springs use rotational deformation to generate torque. They can be used in hinges, clips, levers, mechanical mechanisms, and other components requiring rotational force.

Extension Springs

Extension springs operate under tensile loading and are designed to resist pulling forces. They are commonly used in mechanisms that require a spring to return a component toward its original position.

Other Formed Wire Components

The 1.8 mm stainless steel spring wire can also be considered for other formed wire components where 302 stainless steel and the specified wire diameter meet the design requirements.

How to Select 1.8mm Stainless Steel Spring Wire

Selecting spring wire should be based on the finished spring design rather than wire diameter alone.

1. Confirm the Material Grade

Select 302 stainless steel according to the required material characteristics, forming process, and operating environment.

2. Confirm the Wire Diameter

The wire diameter for this product is 1.8 mm. The diameter should match the required spring geometry and load characteristics.

3. Define the Spring Type

Identify whether the finished component is a compression, torsion, extension, or another type of spring. Different spring structures require different design parameters.

4. Provide Spring Dimensions

For customized requirements, useful information includes wire diameter, coil diameter, free length, number of coils, working length, working load, and deflection.

5. Confirm Surface Requirements

The standard surface for this product is bright. If the finished spring requires coating, plating, lubrication, or another surface treatment, the surface condition should be confirmed before production.

Product Advantages

Defined 302 Stainless Steel Grade

The use of 302 stainless steel provides a clearly specified material grade for spring wire applications and helps customers match the wire specification with their spring design.

1.8 mm Wire Size

The 1.8 mm diameter is suitable for spring designs requiring this specific wire size. Final spring performance should be evaluated together with the complete spring geometry and working conditions.

Bright Surface

The bright surface provides a defined surface condition for spring manufacturing and subsequent processing requirements.

Custom Spring Wire Specifications

Customized requirements can be reviewed based on material grade, wire diameter, spring design, surface condition, quantity, and application.

SGS Certification

SGS certification or inspection documentation can be provided according to the applicable product and order requirements. The specific certification scope should be confirmed for each order.

Production and Quality Control

For stainless steel spring wire, important quality factors include material grade, wire diameter, surface condition, mechanical properties, and dimensional consistency.

During production, the wire specification should be controlled according to the confirmed material and dimensional requirements. For customized spring applications, the customer's spring design and working conditions should be reviewed before production to ensure that the selected wire specification is appropriate for the intended forming process.

Inspection requirements can include dimensional inspection, surface inspection, mechanical property testing, and verification of the specified material requirements.
