Product Specification

Annealed Stainless Steel Wire with Smooth Surface

Product Introduction

Annealed Stainless Steel Wire is stainless steel wire that has undergone an annealing process to obtain a softer and more ductile material condition. Compared with harder wire conditions, annealed wire is generally selected when the manufacturing process requires easier bending, forming, or other secondary processing.

This product is available in 0.15–12 mm diameters and can be supplied according to different stainless steel grades, dimensional requirements, surface conditions, and mechanical property specifications.

The wire is suitable for manufacturers that require stainless steel wire for subsequent forming and fabrication processes. The appropriate material grade and annealing condition should be selected according to the intended application, processing method, and required mechanical properties.

Technical Parameters

Actual available grades, mechanical properties, tolerances, and surface conditions should be confirmed according to the specific product specification.

What Is Annealed Stainless Steel Wire?

Annealed stainless steel wire is produced by applying a controlled heat-treatment process to stainless steel wire. The purpose of annealing is to modify the material condition and improve ductility for subsequent processing.

For wire manufacturers and fabricators, the annealed condition can be considered when the production process involves:

• Bending

• Forming

• Straightening and cutting

• Wire fabrication

• Further mechanical processing

• Other operations requiring increased ductility

The actual mechanical properties depend on the stainless steel grade, wire diameter, annealing process, and applicable specification.

Annealing and Mechanical Properties

Annealing changes the mechanical condition of stainless steel wire. Therefore, annealed wire should not be treated as equivalent to hard-drawn or spring-tempered stainless steel wire.

For applications requiring high tensile strength, spring properties, or specific fatigue performance, the material condition must be selected according to the engineering requirements.

When purchasing annealed stainless steel wire, buyers should confirm:

• Stainless steel grade

• Wire diameter

• Tensile strength

• Elongation

• Surface condition

• Annealing condition

• Applicable standard

• Intended processing method

This helps ensure that the supplied wire condition is compatible with the customer's manufacturing process.

Smooth Surface

The product is supplied with a smooth surface suitable for subsequent wire processing and fabrication.

Surface requirements should be evaluated together with the wire diameter, material grade, and intended manufacturing process. Different applications may require different surface conditions, so the required finish should be clearly specified during procurement.

Available Diameter Range

The listed diameter range is 0.15–12 mm.

Different wire diameters may be selected according to the requirements of the subsequent manufacturing process. When specifying the wire, buyers should consider the required finished-part dimensions, forming method, equipment limitations, and mechanical properties.

For customized orders, the following information can be provided:

• Material grade

• Diameter

• Diameter tolerance

• Surface condition

• Tensile strength

• Elongation

• Coil weight

• Coil dimensions

• Applicable standard

• End-use application

Applications

Wire Forming

Annealed stainless steel wire can be used as raw material for wire-forming processes where the material needs to undergo bending or shaping.

The suitable wire grade and mechanical condition depend on the forming method and final product requirements.

Bending and Fabrication

For fabricated wire components that require bending, cutting, shaping, or other secondary operations, an annealed condition may be considered when higher ductility is required.

General Industrial Processing

Annealed stainless steel wire can be used as a raw material for various industrial wire-processing applications. The appropriate grade, diameter, and mechanical condition should be selected according to the production process.

Stainless Steel Wire Products

Depending on the material grade and processing requirements, annealed wire can serve as raw material for further manufacturing into formed or fabricated stainless steel wire products.

The final application should determine the required material grade, diameter, surface, and mechanical properties.

Product Advantages

Annealed Material Condition

The annealed condition provides a softer material state compared with harder wire conditions and is suitable for applications where ductility and formability are important.

0.15–12 mm Diameter Range

The available diameter range covers fine to larger stainless steel wire sizes for different processing requirements.

Multiple Material Standards

The product can be supplied according to applicable AISI, DIN, EN, and JIS standards, depending on the selected material grade and specification.

Customizable Mechanical Requirements

Tensile strength and elongation can be specified according to the selected grade, diameter, annealing condition, and application requirements.

Customized Packaging

Coil, spool, and drum packaging can be considered according to the customer's handling, transportation, and production requirements.

Quality Control

For industrial stainless steel wire, quality should be evaluated through measurable specifications rather than general performance claims.

Key inspection items may include:

• Material grade

• Chemical composition

• Wire diameter

• Diameter tolerance

• Surface condition

• Tensile strength

• Elongation

• Annealing condition

• Coil weight

• Packaging condition

For repeat production, keeping the material grade, diameter specification, heat-treatment condition, and inspection requirements consistent provides a clear basis for controlling product consistency.

How to Select Annealed Stainless Steel Wire

The selection of annealed stainless steel wire should start with the processing requirement, rather than diameter alone.

A practical specification sequence is:

Application → Material Grade → Diameter → Surface → Annealing Condition → Tensile Strength → Elongation → Packaging

For example, if the wire will undergo extensive bending or forming, ductility and material condition should be considered alongside diameter. If the finished product requires high tensile strength or spring properties, an annealed wire specification may not be appropriate and another material condition should be evaluated.

Annealed Wire vs. Spring Wire

Annealed stainless steel wire and stainless steel spring wire should not be treated as the same product.

Annealed stainless steel wire is generally selected when a softer and more ductile material condition is required for subsequent processing.

Stainless steel spring wire is designed for applications where the wire's mechanical properties and spring performance are critical.

Therefore, the correct wire condition should be selected according to the final product and manufacturing process rather than using “annealed” and “spring wire” interchangeably.

Frequently Asked Questions

What is annealed stainless steel wire?

Annealed stainless steel wire is stainless steel wire that has undergone an annealing heat-treatment process to obtain a softer and more ductile material condition for subsequent processing.

Is annealed stainless steel wire suitable for making springs?

Annealed wire should not be described as finished spring wire. If the final application requires spring performance, the appropriate spring-wire grade, temper, tensile strength, and other mechanical requirements should be specified separately.

What diameter range is available?

This product is listed in the diameter range of 0.15–12 mm. The exact available sizes should be confirmed according to the selected material grade and production specification.

Can the mechanical properties be customized?

Tensile strength and elongation can be specified according to the material grade, diameter, annealing condition, and application requirements.

What standards can be used?

The product can be specified according to applicable AISI, DIN, EN, and JIS standards, depending on the selected material grade.
