Product Specification

1.2mm 316 Stainless Steel Spring Wire for Corrosive Applications

Product Introduction

1.2mm 316 stainless steel spring wire is designed for spring components and wire-forming applications where stainless steel corrosion resistance is an important material consideration.

The wire is manufactured from AISI 316 / SUS316 stainless steel and supplied in a 1.2mm diameter. The available surface options include bright and soap-coated finishes, allowing buyers to select the surface condition according to forming and application requirements.

For applications exposed to moisture, chemicals, salt-containing environments or other corrosive conditions, 316 stainless steel can be considered when its material characteristics match the actual working environment.

Why Choose 316 Stainless Steel for Spring Wire?

Material selection should be based on the actual working environment rather than diameter alone.

AISI 316 contains molybdenum in its alloy system, making it a suitable material option for applications where corrosion resistance is an important consideration.

For spring applications, buyers should also confirm:

• Required wire diameter

• Spring type and geometry

• Required tensile strength

• Forming process

• Surface condition

• Working temperature

• Exposure to moisture, chemicals or salt

• Applicable material standard

This helps ensure that the selected wire specification matches the final spring design.

1.2mm Spring Wire Applications

The 1.2mm diameter can be used for various stainless steel spring and wire-forming applications, depending on the required mechanical properties and component design.

Compression Springs

Used for components that require axial compression and return force.

Extension Springs

Suitable for spring assemblies requiring controlled extension and recovery.

Torsion Springs

Used in mechanisms where the wire is subjected primarily to twisting.

Stainless Steel Wire Forms

1.2mm 316 stainless steel wire can also be formed into hooks, clips, retainers and other customized wire components.

Corrosive-Service Components

316 stainless steel spring wire can be considered for marine, chemical-processing, humid and other corrosive environments when the actual operating conditions are compatible with the material.

Bright Surface vs Soap-Coated Surface

The surface should be selected according to the forming process and end-use requirements.

Bright surface is commonly selected when appearance and a clean metallic surface are important.

Soap-coated surface can be considered when the wire requires a surface condition suitable for certain drawing or spring-forming processes.

For custom orders, the buyer should specify the required surface together with diameter, grade, mechanical condition and application.

Technical Selection Guide

When purchasing 1.2mm 316 stainless steel spring wire, the following information should be confirmed:

1. Grade: AISI 316 / SUS316

2. Diameter: 1.2mm

3. Surface: Bright or soap coated

4. Spring type: Compression, extension or torsion

5. Mechanical requirement: Required tensile strength or spring temper

6. Standard: ASTM, EN, DIN, JIS or customer specification

7. Packing: Coil or spool

8. Working environment: Moisture, salt, chemicals, temperature and other conditions

Quality and Specification Control

For spring wire, material grade alone does not determine the final performance of the spring.

Production specifications should be controlled according to:

• Stainless steel grade

• Wire diameter and tolerance

• Surface condition

• Tensile strength

• Spring temper

• Coil dimensions

• Applicable standard

• Final spring-forming requirements

For demanding applications, buyers can provide drawings, spring dimensions, working load and environmental conditions so the wire specification can be evaluated accordingly.

Customized 316 Stainless Steel Spring Wire

TOPONE can supply customized stainless steel spring wire according to application requirements.

Customization can include:

• Wire diameter

• Tensile strength

• Surface condition

• Coil weight

• Packaging

• Applicable standard

• Customer-specific specifications

For a quotation, it is recommended to provide the grade, diameter, required quantity, surface, mechanical requirement and application.

FAQ

Is 1.2mm 316 stainless steel wire suitable for springs?

Yes. 316 stainless steel spring wire can be used for compression springs, extension springs, torsion springs and other wire-forming components when the required mechanical condition matches the spring design.

Why use 316 instead of 304 stainless steel spring wire?

316 can be considered when the application requires a higher level of corrosion resistance, particularly in certain moisture, salt or chemical exposure conditions. The final selection should be based on the actual environment.

What surface options are available?

Bright and soap-coated surfaces are available. The appropriate surface should be selected according to forming and application requirements.

Can the tensile strength be customized?

The required tensile strength or mechanical condition should be confirmed according to the wire diameter, spring design, applicable standard and production requirements.

What information should be included in an inquiry?

Provide the stainless steel grade, diameter, quantity, surface, required mechanical condition, spring application and applicable standard. A drawing or spring specification is recommended for customized requirements.
