Product Specification

316 Stainless Steel Spring Wire 0.15–12mm for Corrosion

Product Introduction

TOPONE 316 stainless steel spring wire is made from AISI 316 / SUS316 stainless steel and is designed for spring manufacturing and precision wire forming applications where corrosion resistance is an important material consideration.

The wire is available in diameters from 0.15–12mm, with bright or soap-coated surface options. The 316 grade contains molybdenum, making it suitable for applications exposed to humid, marine, chemical, or other corrosive service conditions.

The 1.2mm diameter is one available specification within the product range. Diameter, surface condition, tensile strength, coil weight, and packaging can be specified according to the requirements of the spring manufacturing process.

Why Choose 316 Stainless Steel Spring Wire?

Corrosion Resistance for Demanding Environments

AISI 316 stainless steel contains molybdenum in addition to chromium and nickel. This composition provides improved resistance to corrosion in many humid, marine, and chemical service environments compared with conventional stainless steel grades.

For applications where the wire may be exposed to moisture, salt-containing environments, or certain chemical media, 316 stainless steel can be considered based on the actual operating conditions.

Wide Diameter Range for Different Spring Designs

The available diameter range is 0.15–12mm, covering fine wire through larger spring wire sizes.

This range allows spring manufacturers to select wire according to spring diameter, load requirements, forming equipment, and component dimensions rather than using a single fixed wire size.

Surface Options for Different Processing Requirements

TOPONE supplies 316 stainless steel spring wire with bright and soap-coated surface options.

Bright surface wire can be selected when surface appearance and a clean wire surface are important. Soap-coated wire can be considered for forming processes where surface lubrication is required.

The appropriate surface should be selected according to the customer's spring-forming equipment and processing conditions.

Specification-Based Production

For spring applications, wire diameter and mechanical properties directly affect forming behavior and the final spring characteristics.

For this reason, orders can be specified by:

• Stainless steel grade

• Wire diameter

• Tensile strength

• Surface condition

• Coil or spool weight

• Packaging requirements

• Applicable standard

This specification-based approach helps match the wire to the customer's production process.

Applications

Spring Manufacturing

316 stainless steel spring wire can be used for manufacturing:

• Compression springs

• Extension springs

• Torsion springs

• Small precision springs

• Industrial springs

• Custom wire forms

Marine and Outdoor Hardware

The corrosion-resistant characteristics of 316 stainless steel make it suitable for selected marine hardware and outdoor components where moisture or salt exposure is a consideration.

Chemical and Industrial Equipment

316 spring wire can be considered for components used around humid or chemically demanding environments, subject to compatibility with the specific chemical medium and operating temperature.

Medical and Precision Components

Fine-diameter 316 stainless steel wire can be used for selected medical, laboratory, and precision wire-forming components where material grade and dimensional requirements need to be controlled.

Wire Forming

The 0.15–12mm diameter range supports different wire-forming applications, including clips, hooks, formed components, and customized stainless steel wire parts.

How to Select the Right 316 Spring Wire

Selecting spring wire should not rely on diameter alone. The following parameters should be evaluated together:

1. Material Grade

Choose AISI 316 when the application requires the corrosion resistance characteristics of 316 stainless steel.

2. Wire Diameter

Select the diameter according to spring dimensions, required load, forming equipment, and design calculations.

3. Tensile Strength

Tensile strength should match the required spring design and forming process. The required range should be confirmed before production.

4. Surface Condition

Bright and soap-coated surfaces provide different processing characteristics. The choice should consider forming equipment, lubrication, and surface requirements.

5. Operating Environment

For marine, humid, chemical, or outdoor applications, evaluate the actual exposure conditions before selecting the material grade.

Quality and Manufacturing Information

TOPONE specializes in stainless steel wire production and supplies spring wire in different grades, diameters, surface conditions, and packaging configurations.

Production specifications can be confirmed according to the customer's technical requirements, including material grade, diameter, tensile strength, surface condition, coil weight, packaging, and applicable standards.

For customized orders, customers can provide the required grade, diameter, tensile strength, quantity, and application. These parameters can then be reviewed before production.
