Inoculation in Cast Iron
Poor base iron nucleation and inoculation can be a typical cause for the formation of poor graphite structures in both gray and ductile irons, which can ultimately lead to the desired mechanical and physical properties not being met. The morphology, chemistry and crystallinity of the recarburizer material can have a major impact on the overall metallurgical quality of the iron. Amorphous carbons, such as acetylene and petroleum coke, do not contribute to the nucleation of the melt, resulting in a lower metallurgical quality iron. To meet this challenge, Superior Graphite developed Desulco®, a high purity form of graphitic carbon with exceptional inoculating capability.
