Red-hot metal refers to metal that has been heated to a high temperature, causing it to glow with a bright red color. This phenomenon occurs when the metal reaches a temperature of around 900 to 1,500 degrees Fahrenheit (about 480 to 815 degrees Celsius). At this stage, the metal becomes malleable, allowing it to be shaped or forged for various applications in industries such as construction and manufacturing. The process of heating metal to this temperature is commonly used in metallurgy and blacksmithing. Tools like forges and kilns are employed to achieve the necessary heat. Red-hot metal is often used to create items like tools, jewelry, and automotive parts, showcasing its versatility and importance in various fields.
