Alloy 600 UNS N06600 Inconel 600® Tubing Nonmagnetic High
Alloy 600 is a nonmagnetic, nickel-based high temperature alloy
possessing an excellent combination of high strength, hot and cold
workability, and resistance to ordinary form of corrosion.
This alloy also displays good heat resistance and freedom from
aging or stress corrosion throughout the annealed to heavily cold
worked condition range.
The high chromium content of alloy 600 raises its oxidation
resistance considerably above that of pure nickel, while its high
nickel content provides good corrosion resistance under reducing
This alloy exhibits high levels of resistance to stress and salt
water, exhaust gases, and most organic acids and compounds.
Alloy 600 is not an age hardening alloy; cold working is the only
available means of hardening. Softening by annealing begins at
about 1600°F (871°C), and is reasonably complete after 10 to 15
minutes of heating at 1800°F (982°C). Above this temperature, grain
growth may be objectionable, although very brief heating at 1900°F
will cause complete softening without undue grain growth. Since the
rate of cooling has no effect on the softening, the material may be
water quenched or air cooled.
Low sulfur reducing furnace atmospheres should be used in forging.
Major hot working should be done between 2300/1850°F, while light
working may be continued as low as 1600°F. No hot working should be
attempted between 1600/1200°F due to lower ductility in that range.
Alloy 600 is machinable in both the hot worked and annealed
conditions. Because considerable heat is generated in machining
this alloy, high-speed steel, cast nonferrous or cemented carbide
tools should be used. The tools should be kept sharp.
Lathe turning speeds with high-speed and nonferrous tools are 35/45
sfm (0.18/0.23 m/s); speeds with cemented carbide tools are 100/175
sfm (0.51/0.89 m/s). (This data should be used as a guide for
initial machine setup only. The figures used are averages. On
certain work, the nature of the part may require adjustment of
speeds and feeds.)
Sulfur-based oil should be used as a lubricant, but should be
completely removed before the machined part is exposed to elevated
temperatures, as in welding.
For higher properties, alloy 600 can be cold worked below 1200°F
Alloy 600 can be joined by the usual welding , brazing, and
