1.2mm 316 Stainless Steel Spring Wire for Corrosive Applications

Product Specification

1.2mm 316 Stainless Steel Spring Wire

1.2mm 316 Stainless Steel Spring Wire is a round stainless steel wire designed for manufacturing springs and elastic metal components. The product has a nominal diameter of 1.2mm and is manufactured from 316 stainless steel.

316 stainless steel contains molybdenum and is commonly selected for applications where the material needs to be considered for corrosive service environments.

ISO 6931-1:2016 specifies technical requirements for stainless steel wire used for springs and spring parts, covering circular wire up to 10mm in diameter and applications exposed to corrosive effects or sometimes slightly increased temperatures.

ASTM A313/A313M specifies requirements for stainless steel round spring wire intended for spring manufacturing, including chemical composition, tensile strength and mechanical testing.

Product Specifications

Specific standards, tensile strength, diameter tolerance, surface condition and supply condition should be confirmed according to the customer's technical specification.

Material Characteristics

316 Stainless Steel

316 is an austenitic stainless steel grade containing molybdenum and is commonly considered when corrosion conditions are an important factor in material selection.

For spring applications, the material grade alone does not determine final performance. The actual service medium, temperature, load, forming process and mechanical properties should also be evaluated.

1.2mm Diameter

The 1.2mm diameter is suitable for small and medium-sized spring components and elastic metal parts.

Wire diameter should be evaluated together with:

• Wire diameter tolerance

• Spring outside diameter

• Spring inside diameter

• Free length

• Number of active coils

• Working load

Designed for Spring Forming

The product is specified as stainless steel spring wire for coiling, bending and related cold forming processes.

ISO 6931-1:2016 provides technical requirements for stainless steel spring wire, while ASTM A313/A313M specifies requirements for stainless steel round spring wire used in spring manufacturing.

Applications

Compression Springs

1.2mm 316 stainless steel spring wire can be considered for compression springs operating under axial compression.

Extension Springs

Suitable for extension springs and elastic components subjected to tensile loading.

Torsion Springs

Can be used for torsion springs where elastic deformation is generated through twisting.

Corrosive Environment Applications

316 stainless steel spring wire can be considered for spring applications where corrosive environmental conditions need to be taken into account, including selected chemical, marine and industrial equipment.

Actual corrosion performance depends on the service medium, concentration, temperature, stress condition, surface condition and other operating factors.

Industrial Equipment

The wire can be used for springs, clips, elastic connectors and other stainless steel spring components in industrial equipment.

Product Advantages

316 Stainless Steel Material

The specified 316 stainless steel grade provides a clear material basis for spring wire selection in applications where corrosion conditions are an important consideration.

1.2mm Diameter

The 1.2mm nominal diameter is suitable for small and medium-sized spring components. Actual dimensional tolerance should be confirmed according to the applicable standard and purchase specification.

Suitable for Corrosive Conditions

ISO 6931-1:2016 specifically covers stainless steel spring wire used for springs and spring parts exposed to corrosive effects, making the standard relevant when selecting wire for such service conditions.

Standards-Based Selection

ASTM A313/A313M and ISO 6931-1 provide technical frameworks for stainless steel spring wire and can be used when defining material, mechanical property and inspection requirements.

How to Select 1.2mm 316 Stainless Steel Spring Wire?

Step 1 — Confirm Material

Confirm the required 316 stainless steel grade and applicable material standard.

Step 2 — Confirm Wire Diameter

Confirm the nominal 1.2mm diameter and required dimensional tolerance.

Step 3 — Confirm Mechanical Properties

Define tensile strength, hardness and other mechanical requirements according to the spring design and forming process.

Step 4 — Confirm Spring Design

Provide spring outside diameter, inside diameter, free length, active coils and working travel.

Step 5 — Confirm Working Environment

For corrosive applications, provide the service medium, temperature, concentration, working cycles and stress conditions.

These parameters help determine whether 316 stainless steel spring wire is suitable for the target operating conditions.

Quality & Technical Documentation

For B2B engineering and purchasing evaluation, the product page can be supported with:

• Chemical Composition

• Tensile Strength

• Hardness

• Diameter Tolerance

• Surface Condition

• Coil Weight

• Material Test Certificate

• Inspection Report

• Applicable Standard

• Packing Specification

ASTM A313/A313M specifically addresses chemical composition, tensile strength and mechanical testing, making these actual technical data more useful than general claims such as “high quality” or “high performance.”

Quality Control

If these processes are actually available at the factory, the product page can present the manufacturing workflow:

Raw Material Inspection → Wire Drawing → Heat Treatment / Stress Relief → Surface Treatment → Diameter Inspection → Tensile Test → Final Inspection → Coil Packing

Actual production and inspection photographs can be added to demonstrate manufacturing experience and process control.

Packaging

The wire can be supplied in coil form according to wire diameter, coil weight, transportation method and customer equipment requirements.

For automated spring forming equipment, coil dimensions, weight and decoiling requirements should be confirmed before ordering.

Technical Inquiry

For evaluating whether 1.2mm 316 stainless steel spring wire is suitable for a specific spring, buyers are recommended to provide:

• Material grade

• Wire diameter

• Spring type

• Spring dimensions

• Required tensile strength

• Working load

• Working temperature

• Working environment

• Applicable standard

• Required quantity

These parameters help evaluate the compatibility between the wire specification, spring design and actual working conditions.
