Below is a list of Carbon Steel Forgings manufacturers from Spring Grove, Illinois. Carbon steel forgings are created through the metallurgical process of forging, in which carbon steel is given a particular shape by the application of a strong compressive force. The metal forging method creates the strongest and most reliable carbon steel products available by deforming the grain of the metal to take on the shape of the part. Carbon steel is a ferrous alloy whose main alloying element is carbon, but it can also contain limited amounts of copper, manganese and silicon. The carbon gives the steel greater hardness and strength, particularly when the steel is heat treated.
