The essential difference between cast iron and cast steel lies in the difference in chemical composition, the microstructure and properties are different. It is generally considered that the carbon content is higher than 2% as iron, and the lower value in steel.
In order to make the metal workpiece have the required performance, the heat treatment process is often essential. Depending on the process, it is divided into quenching, tempering, normalizing, and annealing. Can you tell the difference?

Modern industries have already used computer numerically controlled machine tools for the operation, and CNC machine tools can automatically process any product and component directly according to the program pre-programmed by technicians.
The superalloy material for the direct preparation of parts by the casting method. According to the alloy matrix composition, it can be divided into three types: iron-based casting superalloy, nickel-based casting superalloy, and drill-based casting superalloy.
