Ductile Iron foundries use a variety of carbon additives to increase the carbon content of the ductile iron and austempered ductile iron melt in order to provide a number of beneficial characteristics. The ductile iron and austempered ductile iron must have a specific carbon level to attain the proper carbon equivalent (CE) in order to achieve the desired mechanical properties. To meet this challenge, Superior Graphite has developed Desulco®, the purest form of carbon additive available on the market today. Desulco® is the number one choice recarburizer (charge carbon and ladle additive). (less)
