In fact, cold drawn wire and annealed wire really look very similar, if you do not distinguish them carefully, it is indistinguishable. Cold drawn and annealed wires also have a wide range of applications in the market, but many users do not know how to distinguish between cold drawn and annealed wires. In response to this situation, Yan Xinsen domain editor summarized the understanding of cold drawn wire and annealed wire over the years, and through comparison, the difference between cold drawn wire and annealed wire will be briefly introduced to everyone.
Cold drawn wire is used more in building materials, and the testing standards for cold drawn wire are also different. Cold drawn wire has high strength and can be used in many aspects. The prestressed tendon is used much more. Where plasticity is not required and only strength is required, such steels can be used. Cold drawn wire is a kind of metal cold working. The raw material is wire rod, which is what we often call reinforcing steel. Products produced by a series of processes such as peeling. Is the common wire. Ordinary round steel, if it is forced to pass through a hole smaller than its diameter, the diameter of the round steel will become smaller and the length will be elongated. Repeating this process continuously will make the round steel smaller. . After such plastic deformation occurs, the hardness of the steel will increase and the plasticity will basically disappear.
Annealed wire has good elasticity and flexibility. It can control its softness and hardness during the annealing process. It is made of high-quality iron wire. It is mainly used as binding wire and wire in the construction industry. It is softer and more flexible than ordinary black iron wire, with uniform softness and uniform color. Annealed wire is a soft iron wire product made of low-carbon steel cold drawing, heating, constant temperature, heat preservation and other processes. Iron wire has different components according to its purpose. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet is rolled into a 6.5 mm thick steel bar, that is, a wire rod, and then it is drawn into a wire drawing device to draw wires of different diameters, and the diameter of the wire drawing disk is gradually reduced, and processing such as cooling, annealing and coating The process is made into various specifications of iron wire.
I hope that through the introduction of the above information, you can clearly understand the difference between cold drawn wire and annealed wire, and through reasonable application of cold drawn wire and annealed wire.
