Product Specification

Hard 304 Stainless Steel EPQ Wire with Bright Surface for Kitchen Hardware & Bath Fixtures

Product Introduction

Hard 304 Stainless Steel EPQ Wire is manufactured for wire-formed kitchen hardware, bathroom fixtures, racks, hooks, baskets, holders, and other stainless steel components requiring a firm wire condition and a clean bright surface.

The wire is produced from AISI 304 stainless steel and supplied in a hard condition suitable for applications where the wire condition needs to match the forming method and finished-component requirements.

The standard product range is 0.15–12mm in diameter, with the specific diameter, tolerance, surface condition, and mechanical properties confirmed according to the customer's application.

For visible kitchen and bathroom components, the bright surface provides a clean metallic appearance. For products requiring subsequent forming or processing, the appropriate surface condition can be selected according to the manufacturing process.

Product Specifications

Diameter tolerance, tensile strength, hardness and other mechanical requirements should be confirmed according to the required product condition.

Why Use Hard 304 Stainless Steel Wire?

1. AISI 304 Stainless Steel

AISI 304 is a widely used austenitic stainless steel grade for general fabrication and consumer-product applications.

For kitchen hardware and bathroom components, 304 stainless steel can provide a combination of corrosion resistance, formability, and general-purpose material performance.

The appropriate stainless steel grade should always be selected according to the actual service environment, particularly where the product is exposed to high chloride levels or specific chemicals.

2. Hard Wire Condition

The hard condition is an important consideration when selecting stainless steel wire for forming and fabrication.

Compared with softer delivery conditions, hard wire is generally selected when the production process requires a firmer wire condition or specific mechanical characteristics.

For a finished wire-formed component, the correct condition depends on:

• Wire diameter

• Required tensile strength

• Bending radius

• Forming method

• Finished component geometry

• Required dimensional control

• Subsequent processing

Therefore, hard 304 stainless steel wire should be specified according to the actual forming process rather than simply selecting the hardest available condition.

3. Bright Surface for Visible Hardware

The bright surface is suitable for applications where the stainless steel wire remains visible after fabrication.

Typical products include kitchen racks, bathroom holders, storage baskets, hooks, frames, and other wire-formed hardware.

A suitable surface condition can also help manufacturers maintain the required appearance during subsequent cutting, bending, welding, or assembly processes.

4. Wide Diameter Selection

The product range covers 0.15–12mm, allowing manufacturers to select a suitable wire diameter according to component dimensions and forming requirements.

For this reason, the wire can be considered for both relatively fine wire components and larger wire-formed hardware, subject to the required mechanical and dimensional specifications.

Application Areas

Kitchen Hardware

Hard 304 stainless steel EPQ wire can be used for manufacturing:

• Kitchen storage racks

• Dish racks

• Wire baskets

• Utensil holders

• Kitchen hooks

• Cabinet hardware

• Wire frames

• Kitchen organizers

Bathroom Fixtures

Typical applications include:

• Bathroom racks

• Towel holders

• Shower storage racks

• Soap holders

• Bathroom hooks

• Storage baskets

• Toilet paper holders

• Custom wire fixtures

Custom Wire-Formed Components

The wire can also be processed into customized shapes for manufacturers producing:

• Hooks

• Frames

• Brackets

• Holders

• Clips

• Baskets

• Supports

• Other stainless steel wire forms

The final wire condition should be selected based on the required bending operation and finished geometry.

Hard vs. Soft Stainless Steel Wire

Wire condition is an important factor in stainless steel wire selection.

The actual selection should be based on the customer's forming process, required mechanical properties, and final product geometry rather than hardness alone.

Surface Options

Bright Surface

Recommended for visible stainless steel components where a clean metallic appearance is required.

Typical applications include kitchen racks, bathroom fixtures, hooks, baskets, and other decorative or functional wire hardware.

Soap-Coated Surface

A soap-coated surface can be considered for applications where lubrication is required during subsequent wire forming or processing.

The appropriate surface should be confirmed according to the customer's production equipment and forming process.

Quality Control Considerations

For hard 304 stainless steel wire, quality evaluation should focus on measurable specifications rather than general claims such as "premium" or "high quality."

Important inspection points include:

• Material grade

• Wire diameter

• Diameter tolerance

• Surface condition

• Tensile strength

• Hardness or mechanical condition

• Coil weight

• Packing condition

• Batch traceability

• Applicable material standard

For customized orders, customers can provide drawings, diameter requirements, forming conditions, finished-product applications, and mechanical requirements for technical evaluation.

Packing & Delivery

The wire can be supplied in coil or spool packaging according to the customer's production and handling requirements.

Packing specifications such as coil weight, spool dimensions, labeling, and quantity per package can be confirmed according to the customer's requirements.

For regular production, consistent packing specifications also help manufacturers organize wire feeding, storage, and material identification.

How to Select 304 Stainless Steel EPQ Wire?

Before placing an order, manufacturers should confirm the following parameters:

1. Material Grade

Choose 304 for general applications where its corrosion resistance and fabrication characteristics meet the service environment.

2. Diameter

Select the wire diameter according to the finished component design, required rigidity, and forming method.

3. Wire Condition

Confirm whether the application requires hard, medium, or soft wire according to the forming process.

4. Surface

Choose bright or soap-coated surface according to whether the wire will remain visible or undergo further forming.

5. Mechanical Requirements

Where required, specify tensile strength, hardness, elongation, or other mechanical properties.

6. Packing

Confirm coil or spool requirements based on the customer's wire feeding and production equipment.
