The difference between cast iron and steel is demonstrated in terms of its properties
The steel system is made from pig iron and has higher mechanical strength and toughness. It also has special properties such as heat resistance, corrosion resistance and wear resistanceThe tensile strength of cast iron, the plasticity and toughness than carbon steel low. Although the mechanical properties of cast iron is better than steel, but due to the presence of graphite cast iron for steel has given many less performance. Such as good wear resistance, high damping and low notch sensitivity and excellent machinability of cast iron melting point. Low, about 1200 degrees Celsius, the molten iron flow, due to the volume of expanded graphite crystal, so transfer shrinkage is small, its performance is better than that of cast steel, which is usually made by using casting casting method.
The manufacturing process and their different components. Cast iron with high carbon content, containing iron 90% ~ 95%, 3% ~ 4.5% and a small amount of carbon, silicon, manganese, phosphorus, sulfur and iron alloy; carbon content in 0.2% ~ 1.7%. Cast iron is called steel steelmaking raw materials.
