  • The definition of cold heading steel wire

    Cold heading steel wire is a special steel material that is widely used in mechanical manufacturing and engineering fields. Its production process is different from ordinary steel, mainly by processing and forming the steel through cold heading process. This steel wire has high strength and good toughness and is suitable for making a variety of fasteners and components. The cold heading process is a processing method for plastic deformation of metal materials at room temperature. Compared with hot processing, cold heading can better retain the original properties of the metal, especially in terms of strength and hardness. The process of cold heading involves pressurizing the metal material and transforming it into a specific shape through the mold. During this process, the grain structure of the metal changes, which improves its mechanical properties. The main components of cold heading steel wire are usually carbon steel, alloy steel or stainless steel.

  • Aotian's production capacity, applications and corresponding markets.

    Aotian specializes in producing various high-quality cold-heading grade fine-drawn wire materials for fasteners and other customized metal wire products.
