INCONEL alloy 601 - Web - June 2008

1 INCONEL alloy nickel-chromium-iron alloy 601 (UNSN06601 ) is a general-purpose engineeringmaterial for applications that require resistance to heatand corrosion. An outstanding characteristic ofINCONEL alloy 601 is its resistance to high-temperature oxidation. The alloy also has goodresistance to aqueous corrosion, has high mechanicalstrength, and is readily formed, machined and limiting chemical composition of INCONEL alloy601 is listed in Table 1. The composition is a face-centered-cubic solid solution with a high degree ofmetallurgical stability.

2 The alloy 's nickel base, inconjunction with substantial chromium content,provides resistance to many corrosive media and high-temperature environments. Oxidation resistance isfurther enhanced by the aluminum properties of INCONEL alloy 601 make it amaterial of broad utility in such fields as thermalprocessing, chemical processing, pollution control,aerospace, and power 601 is a standard material of construction forvarious types of thermal-processing applications include baskets, trays,and fixtures for annealing, carburizing, carbonitriding,nitriding and other heat-treating operations.

3 Inindustrial furnaces, the alloy is used for radiant tubes,muffles, retorts, flame shields, strand-annealing tubes,woven-wire conveyor belts, chain curtains, burnernozzles, and electrical resistance heating thermal-processing applications arethermocouple protection tubes, furnace-atmospheregenerators, and infrared radiant applications for alloy 601include process heaters, condenser tubes in sour-waterstrippers, and insulating cans in ammonia alloy is also used for combustor components andcatalyst grid supports in equipment for nitric petrochemical processing, the alloy is used forcatalyst regenerators and air preheaters in themanufacture of high-density pollution-control applications, INCONEL alloy601 is used for thermal reactors in exhaust systems ofgasoline engines and for combustion chambers in solid-waste the power-generation field, alloy 601 is used forsuperheater tube supports, grid barriers.

4 And ash-handling alloy is also used for jet-engine igniters and forcombustion-can liners, diffuser assembles, andcontainment rings in gas turbines for aircraft, industrial,and vehicular ..RemainderAluminum .. 11- Limiting Chemical Composition, %,of INCONEL alloy 601 Some physical constants for INCONEL alloy 601 are listedin Table 2. Thermal and electrical properties at room andelevated temperatures are given in Table 3. Values shownfor thermal conductivity were calculated frommeasurements of electrical resistivity.

5 Specific-heat valueswere calculated from chemical coefficients were determined on aLeitz dilatometer; values were corrected for expansion ofthe quartz specimen holder. Each coefficient listed is theaverage coefficient over the indicated temperature effect of temperature on the modulus of elasticityof alloy 601 is shown in Table 4. The data were obtained bythe dynamic method. The values listed for Poisson's ratiowere calculated from moduli of data reported for physical constants and thermalproperties were determined for annealed CCoonnssttaannttss aanndd TThheerrmmaallPPrrooppeerrttiieessPublic ation Number SMC-028 Copyright Special Metals Corporation, 2005 (Feb 05)INCOFLUX, INCOLOY, INCONEL and INCO-WELD aretrademarks of Special Metals 22- Physical ConstantsDensity, Range, C.

As indicated by thosevalues, the strength level exhibited by the alloy varieswith the form and condition of the optimum condition for alloy 601 depends onthe type of application and the service temperatureinvolved. In general, the solution-treated condition isused for rupture-limited applications (temperaturesof about 1000 F (540 C) and higher).
