Carbon, Graphitic

Name:
Carbon, Graphitic
Detailed information:
A metallurgical term referring to practically pure carbon that forms in pig iron during cooling because the absorbing power of iron for carbon decreases as its temperature falls. It exists in the form of tiny flakes distributed throughout the mass. The tendency of graphitic carbon is to weaken the metal, whereas combined carbon, up to the limit of approximately 0.90%, strengthens it.See Perlite; Cementite; Ferrite.
