PRINCIPAL DESIGN FEATURES

A nickel-chromium precipitation-hardening alloy suited for high strength at temperatures above 1300 F, with useful strength up to 1800 F. The alloy is also has excellent properties and ductility at cryogenic temperatures.

APPLICATIONS

Structural members in hot sections of gas turbines such as discs, thrust reversers and ducts. Heat treat fixtures and cryogenic vessels, springs and fasteners.

MACHINABILITY

Conventional machining techniques used for iron based alloys may be used. This alloy does work-harden during machining and has higher strength and “gumminess” not typical of steels. Heavy duty machining equipment and tooling should be used to minimize chatter or work-hardening of the alloy ahead of the cutting.

INCONEL 625 FORGINGSPRINCIPAL DESIGN FEATURES

This nickel-chromium-molybdenum wrought alloy is an excellent general purpose material for elevated temperature use in high strength, oxidation problem applications. It also has excellent corrosion resistance to many acids and resists intergranular attack and stress-corrosion cracking.

FORGING APPLICATIONS

The alloy finds use in high temperature applications such as heat exchangers and gas turbine components. Because of its good corrosion resistance it is also used in wet scrubbers and some acid process equipment.

MACHINABILITY

May be machined by conventional means. However the alloy tends to work harden ahead of cutting and rigid tooling is essential to avoid chatter and work hardening in front of the tool edge.

FORMING

This alloy can be cold formed by conventional means and tooling. The alloy does work harden during cold working with an attendant increase in strength. This increase in strength may be of value for moderate temperature applications and, in these instances, the formed parts can be left in the cold work hardened condition.

WELDING

Welding is readily accomplished using matching alloy filler metal for the conventional welding techniques.

HEAT TREATMENT

The alloy is furnished in the solution annealed condition. This is done at 2150 F for sufficient time dependent upon section thickness. Following the anneal the alloy may be air cooled.

FORGING

Hot forging can be done by heating the billet to 2100 – 2150 F, but not over 2150. Heavy forging may then be done down to a billet temperature of 1850 F and light forging down to 1700 F. Final reductions of 15 to 20% minimum are recommended to maintain

HOT WORKING

Hot forming may be done by heating the alloy to 2150 F. Because this alloy is engineered for good strength at high temperatures it will resist hot deformation and therefore requires powerful equipment to perform hot forming.

COLD WORKING

The alloy can be cold formed by conventional methods and tooling. See also the comments under “Forming” regarding work hardening.

ANNEALING

Because the alloy work hardens during hot or cold forming it may be necessary to anneal such parts in order to complete forming operations. Annealing is done at 1800 to 2000 F and air cooled. Stress relief of cold worked parts may be accomplished at 110.

INCONEL® (nickel-chromium-iron) alloy 600 (UNS N06600/W.Nr. 2.4816) is a standard engineering material for applications which require resistance to corrosion and heat. The alloy also has excellent mechanical properties and presents the desirable combination of high strength and good workability. The limiting chemical composition of INCONEL alloy 600 is shown in Table 1. The high nickel content gives the alloy resistance to corrosion by many organic and inorganic compounds and also makes it virtually immune to chloride-ion stress-corrosion cracking. Chromium confers resistance to sulfur compounds and also provides resistance to oxidizing conditions at high temperatures or in corrosive solutions. The alloy is not precipitation hardenable; it is hardened and strengthened only by cold work. The versatility of INCONEL alloy 600 has led to its use in a variety of applications involving temperatures from cryogenic to above 2000°F (1095°C). The alloy is used extensively in the chemical industry for its strength and corrosion resistance. Applications include heaters, stills, bubble towers and condensers for processing of fatty acids; evaporator tubes, tube sheets and flaking trays for the manufacture of sodium sulfide; and equipment for handling abietic acid in the manufacture of paper pulp. The alloy's strength and oxidation resistance at high temperatures make it useful for many applications in the heat-treating industry. It is used for retorts, muffles, roller hearths and other furnace components and for heat-treating baskets and trays.

INCONEL® alloy 617 (UNS N06617/W.Nr. 2.4663a) is a solid-solution, strengthened, nickel-chromium-cobaltmolybdenum alloy with an exceptional combination of high-temperature strength and oxidation resistance. The alloy also has excellent resistance to a wide range of corrosive environments, and it is readily formed and welded by conventional techniques. The limiting chemical composition of INCONEL alloy 617 is listed in Table 1. The high nickel and chromium contents make the alloy resistant to a variety of both reducing and oxidizing media. The aluminum, in conjunction with the chromium, provides oxidation resistance at high temperatures. Solid-solution strengthening is imparted by the cobalt and molybdenum. The combination of high strength and oxidation resistance at temperatures over 1800°F (980°C) makes INCONEL alloy 617 an attractive material for such components as ducting, combustion cans, and transition liners in both aircraft and land-based gas turbines.
