Advantages Of Ductile Cast Iron
Ductile cast iron (DGH), also called dry cast ductile iron (DCGI), nodular cast Iron (NDI), spheroidal cast Iron (SPI) and spider metal, is a form of silvery-gray iron found in ductile iron pipes fitted to gas and railway stations. It was manufactured by a Canadian company named Scott & Redfield Company Ltd. The pipes were made for use in the British Railway system (Great Britain) and used in tunnel linings and for civil engineering work. It was adopted by the American railroad system as the mainstay of its ventilation ductwork system. The pipes were also used in the ventilation shafts of the New York City subway system, the Washington DC subway system and other cities throughout the United States.
DGH is a silvery-gray in color with a hardness rating of only 0.5 on the Mohs scale. It has high carbon concentration and low chromium concentration. It has a coarse grain structure that lacks distinct grain ridges that may be observed in other metallurgy grades. Spherical fractures occur frequently in ductile cast iron but this feature does not affect its electrical resistance, thermal conductivity, tensile strength or creep resistance due to creep resistance. In addition, the mechanical properties of DGH are similar to those of graphite and thus it can be used to construct pipe fittings and seals like pipe sleeves and pre-fit pipe joint kits.
Ductile cast irons have the capability to obtain higher heating temperatures and provide higher tensile strength than other common ductile iron alloys. It has the ability to yield at low temperatures with excellent weldability and ductility. The ductile iron's flexibility, its tensile strength and its ductility give it the potential to yield as a second or third-best alternative to stainless steel. It has better wear resistance than stainless steels. It also has better abrasion resistance than carbon steels and carbon alloys.
When DGH is combined with graphite, it produces high-grade ductile cast iron (DGHN) that possesses all of the toughness and wear-resistance characteristics of pure graphite.

It is also capable of hardening at elevated temperatures. When DGHN is mixed with other alloys, it produces high-quality iron (DGH). It has the ability to attain good creep resistance and resist oil drilling.
Since DGH is primarily used for precast construction where it forms an integral component of the product, its mechanical properties need to be as good as possible. This means it should have similar wear resistance and strength as stainless steels. It should also exhibit similar resistance to corrosion of oil drill bits, etc. Its ductility needs to be enhanced so it can resist extreme temperatures and resist catastrophic impacts. Thus, it is important to incorporate features such as high tensile strength and excellent ductility into the fabrication process of precast products.
Cast aluminum alloy generally has the same mechanical properties as ductile cast iron (DGI). However, the major difference observed between the two is the inclusion of magnesium in the former. Cast aluminum alloys that include magnesium usually possess enhanced tensile strength and ductility compared to those that do not. It also exhibits good resistance to creep, stress, austenite cracking and fatigue, and the high carbon (C) content makes it able to exhibit excellent toughness, thermal conductivity, and chemical resistance.
Cast aluminum alloys are most often used in pressure vessels and pipes because of its extreme strength and ductility. These qualities make it highly suitable for use in structures where high-pressure needs to be applied and ductility is needed. Examples include: ball bearings, pumps, valves, oil & gas turbines, forging, and aircraft applications. Although there are many different alloys in existence today, DGI is commonly used due to its superior mechanical properties. There are a few others that possess similar mechanical properties that are used in the same applications. However, DGI is still considered to be the leader when it comes to the application of these materials in construction and engineering projects.
A high-quality ductile cast iron (DGI) sheet metal component can improve mechanical properties and reduce fatigue to a great extent. The higher tensile strength of such components makes them ideal for application in situations where high-pressure needs to be applied. Moreover, the high heat resistance and excellent lubricity make it possible to use them in a variety of applications. As mentioned above, there are many other types of metal alloys that exhibit superior mechanical properties; however, DGI still outshines them in terms of applications. The numerous benefits offered by this alloy make it a worthwhile choice for both manufacturers and consumers.
