Iron is a hard grey metal, and heavier than any of the other elements found on Earth. In fact ductile cast iron provides a wide spectrum of mechanical. Most brake drums and brake discs are today made of grey cast iron. 350 is the ISO numeric designation. Carson Castings has been sourcing quality Ductile, Gray Iron, Steel, and ADI castings at competitive prices to niche markets and Fortune 500 companies since 1956. These continuous cast bars made to this robust specification are a good fit for a variety of applications due to its good machinability, wear resistance and vibration damping proper. When fractured, it is grayish in colour - hence the name (specifically, a fracture will follow along the graphite flakes which are gray). Soucy Belgen produces gray iron of Classes 30, 40, 50 and 60 complying with ASTM A48 Standards. Grey cast iron, as the name suggests, has a grey fractured surface. 3750 wall thickness. Fatigue analysis of cast iron requires special considerations of this asymmetric stress strain response.
