Centrifugal Casting Alloy Indefinite Chilled Roll
Centrifugal Casting Alloy Indefinite Chilled Roll
The outer layer exhibits a remarkable mechanical performance and the quantity of graphite in the roll work layer remains basically unchanged along the depth, producing therefore no adverse effect on the decrease of hardness of work layer. The hardness of roll depends mainly on type of matrix (sorbite, bainite, martensite).
