“How does the powder coating process affect the material properties of cast ductile iron? I understand that during the process of powder coating the temperature reaches up to 400 degrees F. Does this cause the material properties of cast ductile iron to become brittle?”


“The cure temperature of 400 F has only one effect on ductile iron…the release of entrapped gasses. The cast ductile iron does not become brittle since the part is at temperature for a relatively short time (15 to 30 minutes). Furthermore, higher temperatures are required to cause problems with Ductile or any other cast iron.”
