Niobium in cast iron

International Symposium Niobium 2001

The use of niobium in cast iron is a relatively new technology at least compared to the use of niobium in steels. The previous International Symposium on Niobium in 1981 did not cover this topic at all. Recently though some important applications for the use of niobium in various cast irons have been developed and some of these will be discussed in this paper. The use of niobium in some different rolling mill roll materials will be described in detail since this has proved to be a very successful application. The method of producing Indefinite Chill rolls containing niobium is patented by Åkers Sweden AB on a worldwide basis. (AU)
