Cast iron is one of the oldest ferrous metals used in construction and outdoor ornament. It is primarily composed of iron (Fe), carbon (C) and silicon (Si), but may also contain traces of sulphur (S), manganese (Mn) and phosphorus (P). It has a …
به خواندن ادامه دهیدThe resultant cast iron has properties that vary from both grey and white cast iron. In case of malleable cast iron, the graphite structure is formed into irregularly shaped spheroidal particles rather than flakes that are usually present in gray cast iron. This make the malleable cast iron behave like low-carbon steel.
به خواندن ادامه دهیدPhysical properties of cast iron. Thermal conductivity. Cast irons with graphite in flake form conduct heat better than those containing nodular graphite, and much better than white cast iron. Generally, any given steel will not conduct heat as well as grey cast iron with the same matrix, because the thermal conductivity of graphite is very high.
به خواندن ادامه دهیدMelting point of malleable cast iron – ASTM A220 is around 1260°C. Melting point of ductile cast Iron – ASTM A536 – 60-40-18 steel is around 1150°C. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs.

Austenitic gray cast irons contain 14% to 30% nickel and are resistant to mildly oxidizing acid environment. They are also resistant to H 2 SO 4 at room temperature. Compared with unalloyed cast irons, high-nickel cast iron is most resistant to alkalis.
به خواندن ادامه دهیدWhite cast iron shows a white fracture and have the following relative compositions: It consists of Carbon – 1.75 to 2.3%, Silicon – 0.85 to 1.2%, Manganese – 0.10 to 0.40%, Phosphorus – 0.05 to 0.20%, Sulphur – 0.12 to …

به خواندن ادامه دهیدCast iron is a group of iron-carbon alloys with a carbon content of more than 2 to 4 percent. In addition, varying amounts of silicon from 1 to 3% by weight and manganese as well as traces of impurities such as sulfur and phosphorus. Cast iron is made by reducing Iron Ore in …
به خواندن ادامه دهیدCast iron is a group of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks …
به خواندن ادامه دهیدIn materials engineering, cast irons are a class of ferrous alloys with carbon contents above 2.14 wt%. Typically, cast irons contain from 2.14 wt% to 4.0 wt% carbon and anywhere from 0.5 wt% to 3 wt% of silicon. Iron alloys with lower carbon content are known as steel. The difference is that cast irons can take advantage of eutectic ...
به خواندن ادامه دهیدCast iron cookware is a staple in the arsenal of any good home chef. Cooking food with cast iron brings many amazing benefits - it conserves energy (since it uses less heat and water), adds dietary iron to food and simplifies cooking by providing even heat. Lehman's knows that there's no cookware more suitable for off-grid living, camping and ...
به خواندن ادامه دهیدTypically, cast irons contain from 2.14 wt% to 4.0 wt% carbon and anywhere from 0.5 wt% to 3 wt% of silicon. Iron alloys with lower carbon content are known as steel. The difference is that cast irons can take advantage of eutectic solidification in the binary iron-carbon system.
به خواندن ادامه دهیدThe use of cast iron pipe is generally undesirable in oil or gas service because of its brittleness. If heated by fire and then quenched cast iron can fail. Aluminum. Aluminum pipe performs well at low temperatures and is resistant to external atmospheric corrosion. However, it cannot be used at high temperatures and will react with heavier ...
به خواندن ادامه دهیدCast iron is a brittle & less ductile material with high corrosive strength. Due to its high compressive strengths, it is used to form the base or body of most machines. Cast irons also have a low melting point of around 1200°C which makes them suitable for casting. It is called cast iron because of its casting properties.
به خواندن ادامه دهیدMost cast irons have a chemical composition of 2.5 to 4.0% carbon, 1 to 3% silicon, and the remainder is 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. White cast iron
به خواندن ادامه دهیدCast iron is a term used to describe a family of metal alloys who primary alloying element is iron. Because of its name, some people tend to think that cast iron is basically 100% iron. This is simply not true. In fact, carbon steels have higher amounts of iron element in them than do cast irons.
