Ductile Iron castings are produced for applications requiring strength, toughness, good machinability, and low cost. Ductile Iron contains spheroidal (nodular) shaped graphite, is higher strength than Gray Iron, and weighs about 10% less than steel for the same section size.
Dotson Iron Castings produces ductile iron grades D60, D65, D80, and D100 as cast without heat treatment.
Austempering is a specialized heat treatment which transforms Ductile Iron into a high strength, wear resistant material. The material contains graphite nodules like normal Ductile Iron but also contains an engineered matrix of Ferrite and carbon rich Austenite, referred to as Ausferrite. ADI is also useful in high fatigue-strength and high impact-strength applications. Austempered ductile iron is produced in grade 1 through grade 5.
Today’s economic environment makes it difficult to produce a superior product at the price your customers are willing to pay. Casting conversions can optimize your production and your product. Dotson’s casting experts work hand-in-hand with you to identify casting conversion solutions that drive not only piece price reduction but also significant reductions in assembly time. Contact Dotson to get started.
