    Casting Facts

    There are many grades of ductile iron and several specifying bodies within the U.S.A. The most commonly used are those written by A.S.T.M. and frequently these are used as base references by other specifying bodies or casting consumers.

    Casting Facts – Solution Strength Ductile Iron – A new generation of ductile irons has been developed by Willman Industries. These new grades produce higher strengths with even greater elongation. These grades can be produced as cast with greater uniformity of casting properties than the original ductile iron grades.

     

    Casting Facts – Austempered Ductile Iron – The advantages of using castings for engineering components are well appreciated by design engineers. Of major importance is the fact that the shapes of any degree of complexity and of virtually any size can be produced.

     

    Casting Design as Influenced by Foundry Practice – Austempered ductile iron or A.D.I as it is commonly called, is a ductile iron which is processed by a special treatment. The heat treatment requires an interrupted quench usually into a salt bath. (Dowload PDF)
