Grey iron casting good abrasion resistance and elimination. Because of graphite in cast iron is helpful for lubrication and oil reservoir, so the wearability. Similarly, as a result of the existence of graphite, elimination of grey cast iron is superior to the steel. Process performance is good. Because of the grey cast iron carbon content is high, close to the eutectic composition, low melting point, good liquidity, small shrinkage rate, thus suitable for casting structure or complex thin wall castings. In addition, due to graphite is easy to form a chip breaker when machining, so the grey cast iron can be cutting machining is superior to the steel.
An iron - carbon alloy with a carbon content of more than 2%. The general carbon content of industrial cast iron is 2.5% ~ 3.5%. Carbon is usually in the form of graphite in cast iron, and sometimes in the form of cementite. In addition to carbon, cast iron also contains 1% ~ 3% silicon, as well as manganese, phosphorus, sulfur and other elements. Alloy cast iron also contains nickel, chromium, molybdenum, aluminum, copper, boron, vanadium and other elements. Carbon and silicon are the main elements that affect the microstructure and properties of cast iron.
