Chemical composition
The main difference between malleable steel and cast iron is the chemical composition. Malleable steel is composed of iron, carbon, chromium, nickel and other elements, among which the chromium content is usually high, which makes malleable steel excellent in corrosion and wear. Cast iron, on the other hand, is mainly composed of iron, carbon, and silicon, and usually has a higher carbon content. Therefore, cast iron is harder but less elastic.
Physical properties
The physical properties of malleable steel and cast iron are also different. Malleable steel is usually cast after melting and has high strength, deformability and toughness. Cast iron is a cast alloy with high compressive strength and excellent wear resistance. Due to the different composition and manufacturing process, the physical properties of malleable steel and cast iron are also different.
Processing technology
There are also differences in the processing of malleable steel and cast iron. Malleable steel can be processed and formed in a variety of ways, such as milling, drilling and grinding, etc. At the same time, its physical properties and surface quality can be changed by heat treatment and other methods. Cast iron, on the other hand, is more fragile, prone to cracks and deformation, so more care needs to be taken during processing.
To sum up, both malleable steel and cast iron have their own unique composition and performance characteristics, and are suitable for different industrial fields. Masteel is mainly used in the manufacture of components in high temperature and corrosive environments, such as aero engines, automobile engines and oil drilling tools. Cast iron is usually used in engineering machinery, auto parts, shipbuilding, railway turnouts and other fields, and has a wide range of uses.
