Cast steel
Cast steel is a ferrous material produced by pouring steel into moulds to form components. It combines the shape-making flexibility of casting with the strength and toughness associated with steel, making it suitable for complex, heavily loaded parts such as machinery components, structural castings and industrial equipment.
