Ductile Iron is a kind of cast iron, which is renowned for several properties. For instance, ductile iron has superior impact and fatigue resistance, in addition to elongation, and wear resistance in comparison to cast iron. This is due to the presence of spherical or round graphite structures seen at a microscopical level in the Ductile Iron Pipe Fittings. This is also why ductile iron is referred to as spheroidal graphite iron or nodular iron names. As a result of a higher content of carbon in the metal, the 24 inch Ductile Iron Water Pipe Fittings retains the traditional qualities of cast iron such as high compression strength, abrasion resistance, castability, as well as machinability.
Ductile iron or Di Fittings also has what is referred to as an excellent wear resistance on account of the presence of graphite spheres in the iron.
When any component abrades itself against ductile iron fitting, the surface of the fitting will wear away much slower in comparison to many other metals. Wear resistance is a property of the Ductile Iron Pipe Bend Fittings that is partially inherited from the graphite structures present in the metal which behaves like a dry lubricant on the iron.
Ductile Iron Pipe Mechanical Joint Fittings also dissipates or it gets rid of heat very well and the metal can be machined fairly easily. Although, many manufacturers note that ductile iron is much harder to work with as opposed to regular gray cast iron. Moreover, when Ductile Iron Pipe Grooved Fittings are used, it dampens vibration and sounds much better in comparison to steel. Thus, making ductile iron an ideal match for use in large machines.
