Inconel 693 (UNS N06693)
Category: INCONEL
Overview
INCONEL alloy 693 is a new alloy from Special Metals which offers resistance to high temperature corrosion mechanisms not previously available from a nickel-based alloy. INCONEL alloy 693 offers the best resistance to metal dusting in chemical and petrochemical processing environments of any conventional alloy currently manufactured.
Alloy 693 typically contains 60.5% nickel, 29% chromium, and 3.1% aluminum. the alloy’s high chromium content gives it excellent resistance to oxidation and sulfidation. However, the addition of 3.1% aluminum to alloy 693 vastly improves resistance to other forms of high temperature corrosion as well.
