Cast iron refers to a group of iron alloys that have greater than 2% carbon. Compared to steel, cast iron has a lower melting point and good fluidity making it ideal for casting complex shapes with thin wall sections. Cast iron also offers excellent machinability.
Grey iron contains carbon in the form of flake graphite and is the most commonly used cast iron, it is also known as flake graphite iron. Compared to steel cast iron has lower shock resistance and lower tensile strength, but offers compressive strength on a par with low carbon steels.
SG iron is cast iron containing graphite in the form of nodules - Spheroidal Graphite. SG iron is also known as ductile iron, the rounded graphite nodules produces a more ductile cast iron that inhibits the formation of cracks. SG iron has a greater fatigue and impact resistance compared to grey iron. Ductile iron offers very good compressive strength, some two to three times the tensile strength.
Grey cast iron - current standard BS EN 1561 (2011), equivalent to ISO 185 (2005), supercedes BS 1452
SG iron - current standard BS EN 1563 (2011), equivalent to ISO 1083 (2004), supercedes BS 2789
