Properties

The microstructure consists of matrix and carbide with carbon content of 1.3-2.3%, depending on content of alloy and heat treatment process. The matrix consists of Pearlite or Bainite. With the addition of Cr, Mo and Ni for higher stability of carbide, enhanced high temperature resistance and strengthened matrix. The centrifugal roll has virtually no fall off in the hardness throughout the shell as well as highly wear and high temperature resistance and high load resistance etc.
