Trust Stemming from Reliability
The enhanced ICDP is developed based on the classic Indefinite Chill Double Poured Cast Iron.The microstructure consists of a bainitic / martensistic matrix with Fe3C and MC carbides homogeneously distributed and a certain amount of free graphite fine and also well distributed in the matrix.The rolls are double tempered to avoid retained Austenite and to obtain the right hardness level and the optimum residual stress level.
