Ordinary round steel, if it is forced 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 will make the round steel further smaller.. After this plastic deformation, the hardness of the steel will increase, and the plasticity will basically disappear.
Cold drawn wire is used more in building materials, and the testing standards for cold drawn wire are also different. The high-strength cold Roberts, can be used in many ways, with much of that tendons. Where plasticity is not required, but strength is only required, such steel 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 steel. Products produced through a series of processes such as shelling. It is our common iron wire. Ordinary round steel, if it is forced 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 will make the round steel further smaller.. After this plastic deformation, the hardness of the steel will increase , and the plasticity will basically disappear.

The high-strength cold Roberts, can be used in many ways, with much of that tendons. Where plasticity is not required, but strength is only required, such steel can be used.
