Product Specification

304 Stainless Steel EPQ Wire with Bright Surface | 0.15–12 mm

Product Introduction

304 Stainless Steel EPQ Wire is a bright-surface stainless steel wire designed for applications where surface appearance, dimensional specification, and wire-forming performance are important.

This product uses AISI 304 stainless steel and is available in diameters from 0.15–12 mm. The current product specification identifies the wire as a hard type with a bright surface, making it different from annealed stainless steel wire, which is supplied in a softer material condition.

EPQ wire is commonly considered for stainless steel components that require a clean and consistent wire surface together with the mechanical condition required for subsequent forming and fabrication.

For procurement, the appropriate wire specification should be determined according to the stainless steel grade, diameter, surface condition, mechanical properties, forming process, and final product requirements.

Technical Parameters

Actual diameter tolerance, tensile strength, elongation, grade, and applicable standard should be confirmed according to the specific order specification.

What Is 304 EPQ Stainless Steel Wire?

EPQ is a specific stainless steel wire product category used for applications where wire surface quality and forming characteristics are important.

This product is based on 304 stainless steel and is supplied with a bright surface and hard material condition. The actual mechanical properties depend on the material grade, diameter, processing condition, and production specification.

EPQ wire should therefore be specified according to measurable technical requirements rather than simply described as a general-purpose stainless steel wire.

For industrial purchasing, the key parameters include:

• Stainless steel grade

• Wire diameter

• Diameter tolerance

• Surface condition

• Tensile strength

• Elongation

• Material condition

• Applicable standard

• Coil or spool requirements

Bright Surface

The bright surface is one of the main characteristics of this product.

For kitchen and bathroom accessories, wire surface condition can be important because the finished component may remain visible after fabrication. A bright wire surface can therefore be considered when the production process requires a cleaner metallic appearance.

Surface requirements should be specified together with the wire grade and diameter. Different finishing requirements may require different processing conditions.

Hard Material Condition

The current product specification identifies this EPQ wire as hard type.

This is an important distinction from annealed stainless steel wire. Annealed wire is processed to obtain a softer and more ductile condition, while this EPQ product is specified as hard.

Therefore, the two products should not be treated as interchangeable.

For applications involving bending or forming, the required forming method and final component geometry should be evaluated before selecting the material condition.

304 Stainless Steel Grade

AISI 304 is an austenitic stainless steel grade widely used for fabricated stainless steel products.

For this product, 304 should be treated as the primary material specification rather than using general claims about all stainless steel grades.

When the final application involves specific chemical exposure, temperature, cleaning agents, or other demanding service conditions, the material grade should be selected according to the actual operating environment.

Available Diameter Range

The product diameter range is specified as 0.15–12 mm.

The appropriate diameter depends on the finished component, forming method, required mechanical properties, and manufacturing equipment.

For customized procurement, buyers should specify the required:

• Diameter

• Diameter tolerance

• Material grade

• Surface

• Material condition

• Tensile strength

• Elongation

• Coil weight

• Coil dimensions

This information allows the wire specification to be matched with the customer's production process.

Applications

Kitchen Accessories

304 EPQ stainless steel wire can be used for selected kitchen accessory manufacturing applications where stainless steel material, bright surface, and appropriate wire-forming characteristics are required.

Potential products include wire-based racks, holders, baskets, and other fabricated kitchen components, subject to the required design and processing conditions.

Bathroom Accessories

The wire can also be considered for stainless steel bathroom accessories and fabricated wire components where a bright stainless steel appearance is required.

The appropriate grade and surface condition should be confirmed according to the finished product and service environment.

Wire-Formed Components

The product can be processed into various wire-formed components depending on its diameter, mechanical condition, and the forming equipment used.

For complex bending or forming operations, the required material condition should be confirmed before production.

Product Advantages

304 Stainless Steel

The product uses AISI 304 stainless steel, providing a defined material grade for procurement and production specifications.

Bright Surface

The bright surface is suitable for wire products where surface appearance is an important consideration.

Hard Material Condition

The hard condition provides a defined material state for applications requiring the corresponding mechanical characteristics.

0.15–12 mm Diameter Range

The product covers a wide range of wire diameters, from fine wire sizes to larger wire sizes used in fabricated components.

Multiple Standards

The product information references AISI, ASTM, EN, and JIS standards. The applicable standard should be confirmed according to the selected specification.

Flexible Packaging

The wire can be supplied in coil or spool packaging, with pallet packaging or other customer requirements available for discussion.

Quality Control and Specification

For B2B stainless steel wire procurement, product quality should be evaluated using measurable specifications.

Important inspection items may include:

• Material grade

• Chemical composition

• Wire diameter

• Diameter tolerance

• Surface condition

• Tensile strength

• Elongation

• Material condition

• Coil weight

• Packaging condition

For repeat orders, maintaining the same grade, diameter, material condition, surface requirement, and inspection criteria provides a clearer basis for product consistency.

How to Select 304 EPQ Wire

The selection process should begin with the finished product and manufacturing method.

A practical specification sequence is:

Application → Material Grade → Diameter → Surface → Material Condition → Mechanical Properties → Standard → Packaging

For example, when producing a visible kitchen or bathroom wire component, both the required mechanical condition and surface appearance should be considered.

If the manufacturing process requires extensive bending or forming, the hard condition should be evaluated against the actual forming requirements rather than assuming that all EPQ wire is suitable for every forming operation.

304 EPQ Wire vs. Annealed Stainless Steel Wire

304 EPQ wire and annealed stainless steel wire represent different material conditions.

The correct product should be selected according to the manufacturing process and required mechanical properties rather than using EPQ wire and annealed wire interchangeably.

Frequently Asked Questions

What is 304 EPQ stainless steel wire?

304 EPQ stainless steel wire is stainless steel wire made from AISI 304 and supplied in a defined EPQ product condition. This product is specified with a bright surface and hard material condition.
