Abstract
An improved cast iron and a method for producing cast iron. The method includes incorporating Niobium particles in the step preceding the solidification of cast iron. Besides being applicable to existing cast iron plants, without structural modifications, the method according to the invention allows producing products in the same plant. The cast iron product can exhibit steel characteristics, while being a cast iron. This product includes cast iron with Niobium particles, has a defined composition, exhibits improved characteristics and is useful in a variety of applications.
