1.2mm 304 Stainless Steel Spring Wire for Industrial Spring Applications

Product Specification

1.2mm 304 Stainless Steel Spring Wire

TOPONE 1.2mm 304 Stainless Steel Spring Wire is a cold-drawn austenitic stainless steel wire developed for spring manufacturing and wire forming applications. It is made from AISI 304 / SUS304 stainless steel and is available with bright or soap-coated surface options.

With a nominal diameter of 1.2 mm, this stainless steel spring wire can be supplied in different mechanical conditions and surface finishes according to spring forming requirements. TOPONE supplies stainless steel wire in diameters from 0.15 mm to 12 mm, with specific diameter, mechanical properties and packaging requirements available according to the application.

For spring manufacturers, material grade, wire diameter, tensile strength, surface condition and forming process should be considered together when selecting spring wire. AISI 304 is commonly selected for applications requiring a combination of corrosion resistance, mechanical properties and suitability for wire forming.

Product Specifications

Note: Mechanical properties such as tensile strength should be specified according to the applicable standard, wire diameter and required spring condition. For production orders, the applicable mechanical specification can be confirmed before manufacturing.

AISI 304 Stainless Steel Material

AISI 304 is an austenitic stainless steel grade widely used in wire and spring applications. Its chromium and nickel content contributes to its corrosion-resistant characteristics.

For spring wire, the final mechanical properties are also affected by the cold drawing process, wire diameter and required condition. Therefore, material grade alone should not be used to determine spring performance.

When specifying 1.2mm 304 stainless steel spring wire, buyers should consider:

• Material grade

• Wire diameter

• Diameter tolerance

• Tensile strength

• Surface condition

• Spring forming method

• Required spring type

• Operating environment

• Applicable standard

Manufacturing Process

The wire is manufactured through cold drawing to achieve the required diameter and mechanical condition. During production, dimensional requirements, surface condition and mechanical properties can be checked according to the agreed product specification.

For spring wire applications, the relationship between wire diameter, tensile strength, surface condition and forming process should be considered during material selection.

Surface Options

Bright Surface

Bright stainless steel spring wire is suitable for applications where a clean metallic surface and controlled surface condition are required for subsequent spring forming or component production.

Soap-Coated Surface

Soap-coated stainless steel spring wire provides a lubricated surface that can be suitable for certain cold forming and spring manufacturing processes.

The appropriate surface finish should be selected according to the customer's forming equipment, lubrication requirements and downstream processing conditions.

Applications

Compression Springs

1.2mm 304 stainless steel spring wire can be used for compression spring manufacturing where stainless steel corrosion resistance and suitable spring-forming properties are required.

Extension Springs

The wire can also be used for extension spring production in industrial hardware and mechanical assemblies.

Torsion Springs

For torsion spring manufacturing, wire diameter, tensile strength, surface condition and forming process should be considered together according to the spring design.

Wire Forms

304 stainless steel spring wire can also be processed into clips, hooks, retaining components and other formed wire parts.

Typical Application Areas

• Industrial equipment

• Mechanical components

• Automotive components

• Electrical assemblies

• Hardware components

• Marine hardware

• General spring manufacturing

• Wire forming applications

Product Advantages

1. AISI 304 Stainless Steel

AISI 304 / SUS304 provides a commonly used stainless steel material option for spring and wire-forming applications where corrosion resistance is required.

2. 1.2mm Nominal Diameter

The 1.2mm diameter is suitable for spring designs requiring a relatively compact wire section. Final spring performance should be evaluated together with spring diameter, number of active coils, working load and operating conditions.

3. Cold-Drawn Manufacturing

Cold drawing is used to achieve the required wire diameter and mechanical condition. The drawing process and subsequent inspection are important factors when controlling dimensional and mechanical requirements.

4. Multiple Surface Options

Bright and soap-coated surfaces are available to accommodate different spring forming and processing requirements.

5. Flexible Supply Specifications

TOPONE can supply stainless steel spring wire in different diameters, surface conditions, mechanical requirements and packaging formats according to production requirements.

How to Select 1.2mm Stainless Steel Spring Wire

Before ordering 1.2mm 304 stainless steel spring wire, buyers should confirm the following specifications:

Material Grade

Confirm whether AISI 304 / SUS304 is required or whether another stainless steel grade is specified for the application.

Wire Diameter

Specify the required nominal diameter and diameter tolerance. For this product, the nominal diameter is 1.2 mm.

Mechanical Properties

Specify the required tensile strength or applicable spring-wire class according to the relevant standard and spring design.

Surface Finish

Choose between bright and soap-coated surface according to the forming process and equipment requirements.

Spring Type

Confirm whether the wire will be used for compression springs, extension springs, torsion springs or other formed wire components.

Quantity and Packaging

Confirm the total order quantity and preferred packaging, such as coil, spool or palletized packaging.

Quality Inspection

For stainless steel spring wire, quality evaluation should focus on measurable product characteristics rather than general quality claims.

Depending on the agreed specification, inspection can include:

• Chemical composition

• Wire diameter and tolerance

• Tensile strength

• Surface condition

• Visual inspection

• Coil dimensions

• Weight

• Packaging condition

• Applicable standard requirements

Inspection requirements can be confirmed according to the product specification and customer requirements before production.

Packaging

The 1.2mm stainless steel spring wire can be supplied in coils, spools or palletized packages according to the required wire weight, handling method and customer requirements.

For export orders, packaging can be selected according to transportation conditions, coil or spool weight and downstream production requirements.
