Cast Steel, Semi-Steel & Graphite (AS, AD, GS, Cr)

DURON produces cast steel, alloy semi-steel (Adamite), and graphite steel rolls for breakdown and intermediate hot rolling stands. Through controlled carbon equivalents and heat treatment, the microstructure balances pearlite matrices with cementite networks and dispersed graphite flakes, providing the mechanical yield strength and resistance to fire-cracking required under cyclic thermal-mechanical loading.
