Abstract
A two-phase ductile iron-based alloy which is resistant to oxidation and fidation at high temperatures is disclosed. The alloy contains from about 8 to 20 wt % of Cr; about 6 to 30 wt % of Ni; about 3 to 11.5 wt % of Al; and 0 to 2 wt % of Mo; about 0 to 1 wt % of Si; about 0 to 2 wt % of Mn; about to 0 to 0.1 wt % of C; about 0 to 0.02 wt % of S; about 0 to 0.02 wt % of P; about 0 to 1 wt % of Ti; about 0 to 2 wt % of Nb and Ta; and the balance of Fe. The atomic ratio of nickel to aluminum is between 0.8 and 1.2.
