What are the advantages and disadvantages of the contrast between cast iron and carbon?
The tensile strength, plasticity and toughness of cast iron are lower than those of mild steel. Although the mechanical properties of cast iron are inferior to that of steel, the presence of graphite gives cast iron much less than steel. For example, good wear resistance, high vibration resistance, low notch sensitivity and excellent cutting performance. The low melting point of iron, is 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 of casting casting method;
Using a range of common steel: steel, steel hardness is very big, can be made of metal processing tool, crawler tractor and axle; manganese steel toughness is very strong, can make a spring sheet, coil; molybdenum steel high temperature resistant, crankshaft, aircraft can be especially hard tools; tungsten chromium steel with high hardness, strong toughness can do, machine tool and die; nickel chromium steel corrosion resistance, easy oxidation, also called stainless steel manufacturing, chemical production can be used in acid tower and medical equipment, daily utensils, etc..
Cast iron has high carbon content, poor plasticity, uneven microstructure and poor weldability;Cast iron is the raw material of steelmaking. The steel system is made by pig iron. It has higher mechanical strength and toughness, and has special properties such as heat resistance, corrosion resistance and wear resistance;
