Cold-formed steel (CFS) is the common term for products made by rolling or pressing steel into semi-finished or finished goods at relatively low temperatures (cold working).
The term forged carbon steel represents a combination of two basic metallurgical components, namely carbon steel and forging. Carbon steel is a broad term applied to a range of steel varieties of various compositions excluding stainless steel.Forging is a metal forming process that utilizes repeated force to compress a piece of heated metal stock into the desired final shape.orged carbon steel parts are usually believed to be superior to those made by other methods such as casting. This is due to the fact that the hammering of the metal during forming eliminates most of the microscopic crystalline flaws, such as air bubbles and fissures, which characterize cast parts.
