Graphite Steel Roll (GS)
The characteristics of graphite steel rolls are similar to those of adamite rolls. The main character is that it contains a small amount of fine graphite in its microstructure, which will increase its resistance to fire crack and prevent oxidized scales from adhering. They are suitable for blooming and roughing stands.
