Product Specification

302CHQ 304HQ Cold Drawn Stainless Steel Wire

TOPONE 302CHQ and 304HQ cold drawn stainless steel wire is designed for cold heading and cold forming applications where material grade, wire diameter, surface condition, and mechanical properties need to match the forming process.

Available grades include 302CHQ, 304HQ, 304, and 430, with diameters from 0.15 mm to 12 mm. The wire is supplied with a bright surface and can be produced in soft or semi-soft conditions.

Tensile strength requirements can be customized according to the selected grade, wire diameter, supply condition, and final application. This allows the wire specification to be matched with different cold forming and component manufacturing requirements.

Technical Specifications

Mechanical Properties

Mechanical properties depend on the stainless steel grade, wire diameter, supply condition, and production requirements.

For customized tensile strength requirements, customers can provide the target tensile strength together with the material grade, diameter, supply condition, and application. The production specification can then be confirmed according to the required cold forming process.

Why Choose 302CHQ and 304HQ Stainless Steel Wire for Cold Heading?

Suitable for Cold Forming

Cold heading and cold forming processes require wire with suitable deformation characteristics and controlled dimensions. Material grade, diameter, condition, and mechanical properties should be selected according to the geometry and forming requirements of the finished component.

Multiple Stainless Steel Grades

302CHQ, 304HQ, 304, and 430 grades are available for different cold forming and stainless steel component requirements. Grade selection should consider the required forming characteristics, mechanical properties, corrosion requirements, and final application.

Controlled Diameter Range

The available diameter range is 0.15–12 mm, covering fine wire and larger wire sizes used for different cold-formed components.

Soft and Semi-Soft Conditions

Soft and semi-soft conditions are available. The appropriate condition can be selected according to the forming process, deformation level, and final component requirements.

Customized Tensile Strength

Tensile strength can be specified according to the selected grade, diameter, supply condition, and application. This helps align the wire specification with the customer's cold heading or cold forming process.

Bright Surface

The standard surface is bright. Surface requirements should be considered together with the forming equipment, lubrication system, and subsequent finishing process.

Applications

302CHQ and 304HQ stainless steel cold heading wire can be used for various cold-formed components, depending on the material grade and forming requirements.

Stainless Steel Fasteners

• Screws

• Bolts

• Nuts

• Rivets

• Studs

• Pins

• Washers

• Other fastening components

Cold-Formed Components

The wire can be used as raw material for components produced through cold heading, upsetting, and other cold forming processes. Typical applications include formed stainless steel parts, precision hardware, and industrial components.

How to Select Stainless Steel Cold Heading Wire

Selecting stainless steel cold heading wire should start with the finished component and its forming process. The main factors include material grade, wire diameter, forming method, deformation level, tensile strength, and surface condition.

1. Select the Stainless Steel Grade

Choose 302CHQ, 304HQ, 304, or 430 according to the required combination of forming characteristics, mechanical properties, corrosion requirements, and final application.

2. Confirm the Wire Diameter

Wire diameter should correspond to the blank diameter required for the finished component. The available diameter range for this product is 0.15–12 mm.

3. Define the Supply Condition

Soft and semi-soft conditions are available. The appropriate condition depends on the forming process and the amount of deformation required.

4. Specify Mechanical Requirements

For customized tensile strength requirements, provide the target tensile strength together with the grade, diameter, supply condition, and intended application. These details help determine a suitable production specification.

5. Confirm Surface Requirements

The standard surface is bright. If the finished component requires lubrication, coating, plating, or other surface treatment, the wire surface should be considered as part of the complete manufacturing process.

Production and Quality Control

For stainless steel cold heading wire, product consistency is closely related to material grade, wire diameter, drawing process, supply condition, and surface requirements.

Production specifications should be confirmed according to the customer's required grade, size, mechanical properties, and application. Inspection requirements can include dimensional checks, surface inspection, mechanical property testing, and verification of the specified material requirements.

Factory production and inspection records can be provided according to the confirmed order and specification requirements.
