Hotgewalste

Hotgewalste refers to a steel product that has undergone a hot rolling process. In this manufacturing method, steel billets are heated to high temperatures, typically above their recrystallization point, and then passed through a series of rollers. This process reduces the thickness of the steel and shapes it into various forms such as plates, sheets, bars, or structural shapes. The high temperature during rolling allows for significant deformation of the metal with less force compared to cold rolling.

The resulting hotgewalste steel exhibits a characteristic surface finish, often described as scaled, due to the oxidation that occurs at high temperatures. It also tends to have looser dimensional tolerances and may exhibit some internal stresses. However, the hot rolling process is generally more cost-effective for producing large quantities of steel and is suitable for applications where precise dimensions and surface finish are not critical. Common uses include construction, automotive parts, and manufacturing of various steel components. The microstructure of hotgewalste steel is typically coarse-grained, which can affect its mechanical properties.
