What is a cold steel?
Cold steel is not formed with heat, like most other steels; Instead, it is created with rollers and presses to make the right size and shape. This results in the fact that steel in the form of cold is lighter than other steel and tends to have somewhat more flexibility. Unlike steel with a hot form that is difficult to justify, cold steel for workers is relatively easy to change and bend. This steel is used to make cars, transmission poles and certain buildings.
Most steels are formed at very hot temperatures; The steel is molten, placed in a mold and cooled to form a certain shape. Cold -shaped steel begins as steel boards that are rolling and stamped until the plates are the right size and shape. The rollers will thin the steel so that it can be easy to be bent and the presses add curves and lines to make the steel intended, such as the shape of L or a curved line. While the process is not completely cold because presses and rollers cause heat by friction and movement, heat is not enough tomelting or deformation of steel without further pressure.
Compared to hot steel, cold steel is much lighter. This is because less steel is generally needed to create a similar form in cold pressing; This reduces steel costs and causes it suitable for easy use. It has some more elasticity than hot steel, usually around 29,500 kiloopands per square inch (KSI) or 14 124 bar, compared to 29,000 KSI from Hot Steel (13 885 bar).
Its increased elasticity and initial roller deformations make it easier to work, so workers can easily produce steel formed by cold steel into different shapes. This allows cold steel to be universal because it can be made to suit most of the needs while running. Hot steel comes in a standard shape and is very difficult to justify; Although it makes hot steel good for support, it is usually not that gooddetails.
This steel is used in many items that must be flexible and light. For example, cars that have steel frames need steel that can be easily distorted into the body shape, and the steel must be light or the car will not be able to move quickly. Hot steel is usually used for buildings, but smaller buildings can be made of steel formed at cold if steel does not have to support a huge amount of weight.
