2020-4-16 Cast iron breaks when it is loaded with significant pressure, although the carbon content in cast iron makes this metal good for casting. This type of cast iron is called grey cast iron, and its main characteristic is the grey-colored carbon flakes in its composition. To produce cast iron, iron ore is deoxidized in a blast furnace.

2021-4-23 Malleable cast iron. Malleable cast iron is white cast iron that has been annealed. Through an annealing heat treatment, the brittle structure as first cast is transformed into the malleable form. Therefore, its composition is very similar to that of white cast iron, with slightly higher amounts of carbon and silicon. Ductile cast iron

2021-5-4 Although cast irons are inferior to steel in mechanical properties, these are superior in damping capacity, sliding quality, and resistance to wear, and of course cost. Composition and Cooling Rate of Cast Irons: Carbon, in cast iron, may be in the combined form as cementite, or in the free form as graphite, or both.

3. Iron heated in a current of lighting gas, immediately becomes carburetted and transformed into a very soft, grey, graphite-like, fus- ible cast iron, which is suitable for the finest castings. Steel is never formed in this reaction of lighting gas on cast iron. 4. Steel is formed by the reaction of carbon and nitrogen on iron

Ductile iron casting refers to a process in which magnesium / cerium (as an alloy of magnesium / cerium) is added to cast iron. It reacts with the sulfur and oxygen in the molten iron and changes the way the graphite is formed. Ductile cast iron (also called as spheroidal graphite cast iron or nodular cast iron) has been widely used as a main industrial material in place of high-grade cast iron.

It is the most commonly used cast iron and the most widely used cast material based on weight. Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron. Grey cast iron has less tensile strength and shock resistance than steel, but its compressive strength is comparable to low- and medium-carbon steel.
