UNS N06693

Alloy 693 (UNS NO6693) is a new alloy which offers resis-tance to high temperature corrosion mechanisms not previously available from a nickel-based alloy. Of particular interest to the de-signer is the alloy’s resistance to metal dusting. Alloy 693 offers the best resistance to metal dusting in chemical and petrochemical processing environments of any conventional alloy currently manufactured.
