Overview
As a leading supplier & manufacturer in China, AEETHER supply cost-effective Inconel 693 Products.
INCONEL alloy 693 (UNS N06693) is a new alloy from Special Metals 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. Alloy 693 is protected by U.S. Patent Number 4,882,125.
Corrosion Resistance
Alloy 693 offers superior resistance to metal dusting, a particularly aggressive form of carburization that can cause failure after very short exposures. Atmospheres containing reducing media (e.g. carbon monoxide and hydrogen) are known to induce metal dusting at elevated temperatures. Alloy 693 offers good resistance to sulfidation in both oxidizing and reducing environments containing sulfur. Also, the alloy performed well when exposed to oxide-rich media such as glass frit and fluxing compounds at temperatures up to 1100°C (2012°F).
