Product Description

ASTM B366 Inconel 600 Elbow INCONEL® alloy 600 (UNS N06600) Ni 72.0, Cr 15.5, Fe 8.0 Mn 1.0 C 0.15 Cu 0.5 Si 0.5 S 0.015 Alloy 600 is a nickel-chromium alloy designed for use from cryogenic to elevated temperatures in the range of 2000 deg F(1093 deg C). The high nickel content of the alloy enables it to retain considerable resistance under reducing conditions and makes it resistant to corrosion by a number of organic and inorganic compounds. The nickel content gives it excellent resistance to chloride-ion stress-corrosion cracking and also provides excellent resistance to alkaline solutions. Alloy 600 is non-magnetic, has excellent mechanical properties and a combination of high strength and good workability and is readily weldable. Alloy 600 exhibits cold forming characteristics normally associated with chromium-nickel stainless steels. Typical corrosion applications include titanium dioxide production (chloride route), perchlorethylene syntheses, vinyl chloride monomer (VCM), and magnesium chloride. Inconel 600 is used in chemical and food processing, heat treating, phenol condensers, soap manufacture, vegetable and fatty acid vessels and many more. Characteristics • Resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy 200 and 201 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions. • Virtually immune to chlorine ion stress corrosion cracking. • Demonstrates adequate resistance to organic acids such as acetic, formic and stearic. • Excellent resistance to high purity water used in primary and secondary circuits of pressurized nuclear reactors. • Little or no attack occurs at room and elevated temperatures in dry gases, such as chlorine or hydrogen chloride. At temperatures up to 550C in these media, this alloy has been shown to be one of the most resistant of the common alloys. • At elevated temperatures the annealed and solution annealed alloy shows good resistance to scaling and has high strength. • The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases. • Under alternating oxidizing and reducing conditions the alloy may suffer from selective oxidation. Applications • Thermocouple sheaths. • Ethylene dichloride (EDC) cracking tubes. • Conversion of uranium dioxide to tetrafluoride in contact with hydrofluoric acid. • Production of caustic alkalis particularly in the presence of sulfur compounds. • Reactor vessels and heat exchanger tubing used in the production of vinyl chloride. • Process equipment used in the production of chlorinated and fluorinated hydrocarbons. • In nuclear reactors uses are for such components as control rod inlet stub tubes, reactor vessel components and seals, steam dryers and d separators in boiling water reactors. In pressurized water reactors it is used for control rod guide tubes and steam generator baffle plates etc. • Furnace retort seals, fans and fixtures. • Roller hearths and radiant tubes, in carbon nitriding processes especially.
