INCONEL alloy 693 high temperature corrosion alloy round bar factory
INCONEL alloy 693 (UNS N06693) is a new alloy which offers resistance to high temperature corrosion mechanisms not previously available from a nickel-based alloy. Of particular interest to the designer is the alloy's resistance to metal dusting. 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. Like its predecessor, INCONEL alloy 690, 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.
