Grey cast iron : Grey Cast Iron (Gray iron castings) is so called because of the colour of the fracture face. It contains 1.5-4.3% carbon and 0.3-5% silicon plus manganese, sulfur and phosphorus.  Grey cast iron has graphitic flakes which deflect a passing crack and initiate countless new cracks as the material breaks. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is comparable to low and medium carbon steel.
