Cast carbon steel takes the carbon as the main alloy elements. It has a strong mechanical properties and good casting performance. Therefore, the carbon steel is widely used to cast kinds of custom casting parts.
Carbon steel, low alloy steel, and tool steel castings are used in several industrial applications and environments. With their numerous grades, steel and their alloys can be heat-treated to improve its yield and tensile strength; and, adjust hardness or ductility to the engineer's application needs or desired mechanical properties.
According to the level of carbon content, carbon steel for casting is generally divided into low carbon steel, medium carbon steel and high carbon steel. The cast carbon steels of all countries in the world are generally classified according to their strength, and corresponding grades are formulated.
Regarding the chemical composition of carbon steel, except for phosphorus and sulfur, there are no restrictions or only upper limits on other chemical elements. Under the above premise, the chemical composition of cast carbon steel is determined by the foundry according to the required mechanical properties.
The heat treatment methods of carbon steel castings are usually annealing, normalizing or normalizing + tempering. For some high carbon steel castings, quenching and tempering can also be used, that is, quenching + high temperature tempering, so as to improve the comprehensive mechanical properties of carbon steel castings. Small carbon steel castings can be directly quenched and tempered from the as-cast state. For large-scale or complex-shaped carbon steel castings, it is appropriate to perform quenching and tempering treatment after normalizing treatment.
