How do I reduce the efect of macrasegregation of carbon in steel?
(OP)
I'm having macrosegregation problems with a 0,3 %wt carbon steel. The diameter of the part is quite thick, 80 mm, so I found carbon percent of 0,28% in the surface and 0,39% in the segregation region (in the center of the part).

Let the castings cool in the mold for a longer time,this might help reduce the carbon gradient. There is no substitute for homogenizing,you need to do it for a longer holding times to eliminate the carbon gradient.Are there any other alloying elements also in the steel exhibiting segregation pattern?
