Jan 06, 2010Graphite flotation does not effect tensile poperties. It can reduce fatigue resistance marginally but i doubt it would cause a failure there maybe other factors that have caused this. If it has then your design criteria is too tight. This should be reviewed and fully investigated and understood. The main problem with graphite flotation is a

Technical Report: The occurrence of graphite flotation in a
Graphite flotation was observed to occur to an extent that depends on the carbon equivalent (C.E.) and casting modulus. In the present casting, graphite flotation occurred when the C.E. exceeded 4.42. Graphite particle clustering and graphite morphology degeneration into exploded nodules and compacted flake form was observed in the flotation zone.

Floating defect of graphite in ductile iron casting
As a result, the surface quality and mechanical properties of castings are deteriorated. The floating of graphite is related to the carbon equivalent of the molten iron, the geometry of the casting and the cooling rate. In addition, it may also be related to the nucleation degree of the molten iron. The effect of cooling rate is more obvious.
