Cast Steel Production | Metal Casting Blog

Cast steel production. The practice of casting steel dates back to the late 1750s, much later than the casting of other metals. The high melting point of steel, and the lack of technology available to melt and process metals, delayed the development of a steel casting industry. These challenges were overcome by advances in furnace technology.
