Properties of gray cast iron

1) The performance of gray cast iron mainly depends on the performance of the matrix and the quantity, shape, size and distribution of graphite. Among them, gray cast iron composed of fine-grained pearlite matrix and flake graphite has the best performance and the widest application range. 2) The tensile strength and plasticity of gray cast iron are much higher than that of steel with the same matrix, but graphite flakes have little effect on the compressive strength of gray cast iron, so gray cast iron is widely used as parts that bear compressive loads, such as machine seats and bearings. Seat etc. 3) Gray cast iron has good casting performance and cutting performance, and the presence of graphite can reduce wear and shock. Properties of Ductile iron Casting

The main components of ductile iron Compared with gray cast iron, the main features are high C, high Si, and low S. Microstructure of nodular cast iron

Matrix + spherical graphite. There are four types of substrates: F, P, F+P, and B. Schematic diagram of the structure of ductile iron, as shown in Figure 2: Production method of nodular cast iron It is obtained by spheroidizing and inoculating molten iron. The properties of ductile iron Spherical graphite has the least effect on the splitting of the matrix, so it has high strength, good toughness, plasticity and machinability.
