Steel can be subdivided into carbon steel, low-carbon steel and high-carbon steel according to carbon content; steel also can be divided into hammered steel, cast steel, hot-rolled steel and cold drown steel according to different forming ways.

Roll forging is a process where round or flat bar stock is reduced in thickness and increased in length. Roll forging is performed using two cylindrical or semi-cylindrical rolls, each containing one or more shaped grooves. A heated bar is inserted into the rolls and when it hits a stop the rolls rotate and the bar is progressively shaped as it is rolled through the machine. The piece is then transferred to the next set of grooves or turned around and reinserted into the same grooves. This continues until the desired shape and size is achieved. The advantage of this process is there is no flash and it imparts a favorable grain structure into the workpiece.

Examples of products produced using this method include axles,rings, tapered levers and leaf springs.
