Inconel alloy 693 tube insert’s or ferrules are Excellent Resistance to Metal Dusting and High Temperature Corrosions in heat exchanger and boiler tube at tile of passing the heat.
Ferrule material or high temperature tube inserts A new alloy from Special Metals called INCONEL alloy 693 (UNS N06693) provides resistance to high temperature corrosion mechanisms that were previously unavailable in nickel-based alloys. The alloy’s resistance to metal dusting is of special relevance to the designer. Of all the common alloys now in production, alloy 693 has the best resistance to metal dusting in chemical and petrochemical processing settings. Usually containing 60.5% nickel, alloy 693 significantly increases resistance to various types of high temperature corrosion.

Fabrication and Heat Treatment
INCONEL 693 is easy to fabricate by using the traditional methods. The forming and machining characteristics are similar to those of INCONEL 600 or 690.
Welding
Weldability of INCONEL 693 is good especially for matching and dissimilar joints. It is recommended that this process be performed in the annealed condition. The two commonly used welding processes are gas tungsten arc-welding and gas metal-arc welding. The ideal filler metal is INCONEL Filler Metal 53MD, which is a near-matching composition welding product
Annealing
Annealing of INCONEL 693 is performed by heating to 1010° to 1066°C (1850°-1950°F), holding for a time corresponding with section thickness, which is followed by rapid cooling in air or water quenching.
Applications
INCONEL 740 is chiefly used in the following application areas:
- Petrochemical for syntheses gas production
- Water to energy and biomass incinerators
- Thermal processing
- Burner nozzles
- High-temperature fuel cell reformers
