Heat treating a two metre saw blade, Slack Sellars & Co Ltd, Sheffield, South Yorkshire, 1963. The process of heat-treating metal involves the heating up and rapid cooling of the metal, which changes the properties of the metal but not the shape. Heat-treating is used to harden, soften or increase the ductility of the metal, depending on its intended use.
