Hot rolled steel is a type of steel that is formed using the hot rolling process at a temperature above its recrystallization temperature. Steel is easier to shape at this elevated temperature. Compared to cold rolled steel, hot rolled steel typically does not require any postforming heat treatment. Hot rolled steel usually has more mill scale ...
