Din 2.4665 is a nickel-chromium-iron-molybdenum superalloy with outstanding high temperature strength, oxidation resistance, and fabricability. Din 2.4665’s oxidation resistance is excellent up to 2200° F. This nickel steel alloy has also been found to be exceptionally resistant to stress-corrosion cracking in petrochemical applications. Matrix stiffening provided by the molybdenum content results in high strength in a solid-solution alloy having good fabrication characteristics. Although this nickel alloy is primarily noted for heat and oxidation resistance it also has good resistance to chloride stress-corrosion cracking, carburization, and excellent resistance to reducing or carburizing atmospheres. Two common conditions that often lead to early failure in high temperature alloys, carburization and nitriding, Din 2.4665 resists.
Characteristics
RESISTANCE TO OXIDATION
The outstanding oxidation resistance of Din 2.4665 is illustrated below. Tests were conducted by exposing samples to dry air at 2000 Deg. F. and to dry air pressurized to 300 psi at 1750 Deg. F. Two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. Din 2.4665 excels in both respects due to the formation of a protective, tenacious oxide film.
RESISTANCE TO CARBURIZATION AND NITRIDING
Din 2.4665 also resists carburization and nitriding, two common conditions which often lead to early failure in high-temperature alloys. After 100 hours in petroleum coke, four other materials were completely penetrated by carburization; whereas, Din 2.4665 specimens showed no carburization at all. Of ten materials evaluated in an atmosphere of hydrogen, nitrogen and ammonia at 1100 Deg. F. and 25,00 psi for 64 days, Din 2.4665 had a nitride case less than one-fourth as thick as the closest competitive material without intergranular attack.
Applications
The alloy finds use in petrochemical process equipment and gas turbines in the hot combustor zone sections. Also used for structural components in industrial furnace applications because of the excellent oxidation resistance.
Din 2.4665 is recommended especially for use in furnace applications because it has unusual resistance to oxidizing, reducing, and neutral atmospheres. Furnace rolls made of this alloy were still in good condition after operating for 8700 hours at 2150 Deg. F. Furnace trays, used to support heavy loads, have been exposed to temperatures up to 2300 Deg. F. in an oxidizing atmosphere without bending or warping. Din 2.4665 is equally suitable for use in jet engine tailpipes, afterburner components, turbine blades, nozzle vanes, cabin heaters, and other aircraft parts.
Gas turbine combustion cans and ducting, heat-treating equipment.
Din 2.4665 has wide use in gas turbine engines for combustion zone components such as transition duct, combustor cans, spray bars and flame holders as well as in afterburners, tailpipes and cabin heaters. It is recommended for use in industrial furnace applications because it has unusual resistance to oxidizing, reducing and neutral atmospheres. Furnace rolls of this alloy were still in good condition after operating for 8,700 hours at 2150 degrees F (1177 degrees C). Din 2.4665 is also used in the chemical process industry for retorts, muffles, catalyst support grids, furnace baffles, tubing for pyrolysis operations and flash drier components.
Useful Properties for Aircraft and Furnace Parts - Din 2.4665 is recommended especially for use in furnace applications because it has unusual resistance to oxidizing, reducing, and neutral atmospheres. Furnace rolls made of this alloy were still in good condition after operation for 8,700 hours at 2150 Deg. F (1177 Deg. C).

Fabrication with Din 2.4665
Din 2.4665 has excellent forming and welding characteristics. It can be forged and, because of its good ductility, can be cold worked. It can be welded by both manual and automatic methods including shielded metal arc, gas tungsten arc, gas metal arc and submerged arc processes. The alloy can also be resistance welded. For hot forming, the alloy should be heated to a starting temperature of 2150° F (1175°C).
