What is Cold Heading Quality (CHQ) wire

Cold Heading Quality (CHQ) Wires is a kind of steel wire that is manufactured by drawing and annealing wire rods. CHQ wires are typically used for making critical fasteners, cold heading and cold extrusion components. 

The major applications of CHQ wire include Fasteners, Cold Forged Parts, Bearings, production of coupling parts such as bolts, nuts, and small screws, and parts for machines.

The manufacturing of the Cold Heading Quality (CHQ) Wires involves two important process named 

  • HRPPD (Hot Rolled Pickling, Phosphating and Drawing)
  • SAPPD (Spherodized Annealed, Pickling, Phosphating, and Drawing)
  • DAPPD (Drawing, Spherodized Annealed, Pickling, Phosphating, and Final Drawing)

Our CHQ wires come in the following specifications:

Steel Grade: Alloy steel ,Carbon steel, Boron steel, Mild steel, and Bearing steel

Diameter: 1.2mm – 32.0mm

Application: For Cold Heading or Cold Forging for making various fasteners such as screw, self-clinching nut, bolts, studs, nail & rivet for use in automobile, defence, construction, general engineering, electronics & aerospace industry.

Packaging: In 100 – 2500Kgs weight coils wrapped with stretch film and HDPE with proper identification tags or on carriers (formers) in coil weights from 1000 – 2500Kgs.

Type: SAPPD (Spheoridised Annealed Pickled Phosphated Drawn) Wires, PPD (Pickled Phosphated Drawn) , DAPPD (Drawing, Spherodized Annealed) Wires, Annealed Wires, SA (Spheroidised Annealed in Process) Wires.
