Hot rolled steel for sale in bulk
During the hot rolling process, the steel is processed at high temperature. On the contrary, cold rolling takes place at room temperature. However, whether the rolling is cold or hot affects the nature of the sheet obtained and its general application. However, whether the rolling process is hot or cold has nothing to do with the properties and quality of the steel. For more information on hot rolled steel sold in bulk, visit our site.
What is hot rolled steel?
Train tracks, construction sheet, rebar, angle iron, stud etc. Many steel products are produced in the same way. However, in the final stage, it is cut to the desired length instead of rolling. There is less control over the final shape as the heated steel shrinks as the temperature decreases. As a result, the hot rolling method is suitable for the production of products where very high dimensional accuracy is not important, such as train tracks, building sheets, rebars, angles, studs and other construction hardware. Metal surface roughness and scaling (due to post-heating cooling process)
The roundness and roughness of the edges of the product (due to the volume changes during cooling. Of course, this feature is suitable for the production of construction sheet and rebar). Hot rolled steel generally needs more processing than cold rolled steel, so its price is lower. Cooling of hot rolled steel can be done at room temperature, so that it can normalize the steel (i.e. hot rolled steel is free of residual stresses.a steel molecule is formed. The hot rolling method is used to produce steel products where the strength of the steel is more important than the exact dimensions and surface finish.
If necessary, methods such as sandblasting, sandblasting and acid washing can be used for polishing and stripping the steel surface. After removing these shells, polishing, polishing and polishing can be done. It has a better surface quality and less tolerance. The surface is smooth, polished and generally oily. For this reason, cold rolled sheets are also called oil layers. Bars are straight and square, sides and corners are precise. Pipes are uniform and smooth. Cold rolled steel, due to its higher quality surface than hot rolled steel, is often used in more precise technical projects and where appearance is of paramount importance.
Of course, the price is higher as well, as more processing is done on refined steel. Cooling processes cause internal stress on the material. In other words, sometimes working with cold rolled steel (cutting, sanding, or welding) releases the internal stresses of the cold rolled steel and ultimately leads to metal warping.
