┃ Overview

UNS N0660 is a nonmagnetic, nickel-chromium alloy. 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 also has excellent mechanical properties, high strength and good workability. But the alloy is not precipitation hardenable; it is hardened and strengthened only by cold work. The versatility of Inconel 600 has led to its use in a variety of applications involving temperatures from cryogenic to above 2000°F (1095°C).

┃ Application

Heat-treating Industry: Retorts, muffles, roller hearths and other furnace components and for heat-treating baskets and trays.

Chemical Industry: 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.

Electronic Field: Parts as cathode-ray tube spiders, thyratron grids, tube support members and springs.

Aeronautical Field:  Engine and airframe components which must withstand high temperatures. Examples are lockwire, exhaust liners and turbine seals.

Nuclear Applications: Nuclear reactors

┃Corrosion Resistance

Inconel 600, which contains a minimum of 72% nickel and 14% chromium, makes it superior to commercially pure nickel under oxidizing conditions， and possesses the ability to resist a variety of corrosives. It's high nickel content enables it to retain considerable resistance under reducing conditions, and also provides excellent resistance to alkaline solutions and strongly oxidizing acid. However, the oxidizing effect of dissolved air alone is not sufficient to insure complete passivity and freedom from attack by air-saturated mineral acids and certain concentrated organic acids.

┃ Machining

Alloy 600 is slightly more machinable than Type 304 stainless steel and slightly less machinable than Type 303 free-machining stainless steel.  The alloy is best handled on heavy-duty equipment using cutting tools large and heavy enough to withstand the loads and to quickly dissipate the heat generated. Tools must be sharp and have the proper geometry.

┃Welding

Inconel 600 can be easily welded using conventional welding methods. The recommended welding materials for joining alloy 600 are Inconel welding electrode 182 for shielded metal-arc welding, Inconel filler metal 82 for gas tungsten-arc and gas metal-arc welding, and a combination of Inconel filler metal 82 and Incoflux 4 submerged arc flux for the submerged-arc process.
