Can the gray iron be forged?

Can not be forged. Below is the tissue and performance of various tissues and mechanical performance descriptions of the gray cast iron [Organization]: It can be regarded as a carbon steel matrix and shelled graphite. Different gray cast irons in the substrate are divided into three categories: ferrite matrix ash cast iron; iron cast iron cast iron; gray cast iron of pearlite substrate. [Mechanics Performance]: The mechanical properties of the ash cast iron are related to the form of the matrix and the form of graphite. The sheet -like graphite in the gray cast iron is severely split on the matrix. It is easy to cause stress concentration at the sharp corner of the graphite, which makes the tensile strength, plasticity and toughness of the gray cast iron lower than the steel. The worst cast iron in the part. At the same time, the mechanical properties of the matrix tissue on the ash cast iron also have a certain impact. The graphite of the gray cast iron of the iron body substrate is large, and the strength and hardness are the lowest. The intensity and hardness are mainly used to create more important castings. The graphite of the gray cast iron of the iron body of the iron body is slightly larger than that of the pearlite ash cast iron, and the performance is not as good as the pearlite ash cast iron. Therefore, the gray cast iron of the pearlite substrate is used in the industry. [Other performance]: Good casting performance, good vibration reduction, good wear resistance, good cutting processing performance, low gap sensitivity
