What is CHQ Wire Rod
The term “cold heading quality” (CHQ) refers to steel wire that produced by drawing and annealing wire rods. Three main cold heading processes – HRPPD Process, DAPPD Process, and SAPPD Process. – Employed to craft CHQ Wires. This type of steel made with specific raw materials and chemistry in order to be able to endure swedging, heading, and forming without a decrease in quality. Because of these characteristics, CHQ Wire is suitable for making fasteners such as bolts, nuts, screws, rivets, nails, etc. SMC places extreme importance on the surface and chemical composition of the wire when producing it so that they can offer their customers top-notch products.
Process of CHQ Wire Rod
Pickling & Coating
The hot-rolled coil or wire rod passes through the pickling line. Where hydrochloric acid solution used to remove surface scale for clean surface finish before further processing and to form a lubrication film on the surface to reduce friction during drawing and cold working. During the process, the Gantry Crane moves between the tanks.
Intermediate Drawing
Wire drawing machine consists of Supply Stand, Drawing Drum, Take up stages, which produce half-finished coil products for spheroidized annealing.
Spheroidized Annealing
Cold work enhanced by this annealing process of obtaining spheroidized carbides. Once inserted in the heat treatment furnace, the process takes place in the order of controlled heating up to a given time, temperature and furnace atmosphere, followed by maintaining such temperature for a specified period and controlling cooling in accordance with the intended purpose. Automatic heat cycles control this process.
Skin Pass
The wire drawing machine produces half-finished coils where products meet the customers’ needs in terms of the size and mechanical properties of products.
Packing of Cold Heading Quality Steel Wire Rod（CHQ Wire Rod）:
Our Products packed and labeled according to the regulations and customer’s requests. Great care taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels tagged on the outside of the packages for easy identification of the product I. D. and quality information.

What Are The Main Cold Heading Applications?
Cold heading wire often used in the production of a variety of fasteners, including screws, nails and bolts. It is also integral to sectors like automotive manufacturing, medical implants, aerospace engineering, the building trade and general hardware. The strength and finish of the wire must be of an exceptional quality so that it can withstand difficult conditions. Thus, it’s essential to select a type of wire which boasts both excellent tensile strength and a smooth surface.
Critical Fasteners
CHQ wires used in a range of industries such as automotive, engineering, appliances and cold forging. As it enables production to be quicker and cost-effective, cold working is becoming increasingly prominent for fastener applications. It offers an impressive surface finish and precise dimensions in the finished product. Nevertheless, many regions possess different levels of deformation which can cause considerable variations in hardness if the cold heading method is employed. Thus, it’s crucial that the raw material has the correct balance and mechanical properties to reduce this scattering.
Cold Forged Parts
CHQ wires commonly employed in the automotive industry for cold forged parts. Such as engine, transmission, suspension and interior components. These parts demand exquisite materials that provide superior surface finish and dimensional accuracy. Additionally, they must possess sufficient strength to survive severe operating conditions. During operation, these parts must endure extreme temperatures; thus, the properties of the steel should be steadfast over extended periods of time. CHQ wires are suitable for this type of usage due to their strength, durability and ease of workability.
Armature Shafts
A common application for CHQ wire is in armature shafts, which are important components of electric motors and generators. These shafts must be able to withstand significant torque.
Ball & Roller Bearing
We also used CHQ wire in ball and roller bearings. Ball and roller bearings transmit power and motion across a wide range of industrial applications, and they must be able to withstand significant torque.
Ball Joint Stud
The ball joint studs commonly made from cold heading wire, which is used to join two metal parts together. They are available in a variety of sizes and styles, making them a popular choice for use in automotive and engineering applications.
Chain Pin
Cold heading wire chain pins used in automotive and engineering applications to connect the links in a chain. They are obtainable in a variety of sizes, depending on the application.
Cylinder Head Bolt
In most engines, cylinder head bolts connect the engine block, cylinder head gasket, and cylinder head. Cylinder head bolts are made of stainless steel or carbon steel, and they are hexagonal in shape.
Drill Bit Pieces
For drilling a hole in a surface, drill bit pieces are made from cold headed wire to ensure strength and durability.
Screw
The screw is a fastener used to join two pieces of metal together. It is made from cold heading quality wire for strength and durability. Screws are commonly used in automotive and engineering applications.
Nuts & Bolts
CHQ wires made from cold heading quality steel and are used in a variety of applications, including nuts and bolts.
Tire Spoke
Wheel spokes are the parts that connect the hub to the tire and hold it in place. They are either steel or aluminum, depending on the frame design. They usually arranged in a diamond pattern.
Tubular Rivets
Tube rivets are used to connect two surfaces together. They are typically made from stainless steel, and are used in a variety of industries. They are especially useful when making connections where weight is a concern, such as with aircraft fuselages.
