Corrosion Resistance:
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 conditions. This alloy exhibits high
levels of resistance to stress and salt water, exhaust gases, and most organic
acids and compounds.
Impact Resistance:
Alloy 600 shows excellent toughness even at subzero temperatures. The
following are typical results for standard size Charpy V-Notch impact
specimens machined from plate.

Heat Treatment:
Alloy 600 is not an age hardening alloy; cold working is the only available
means of hardening. Softening by annealing begins at about 1600 Degrees F (871
Degrees C), and
is reasonably complete after 10 to 15 minutes of heating at 1800 Degrees F (982
Degrees C).
Above this temperature, grain growth may be objectionable, although very brief
heating at 1900 Degrees 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.
Workability:
Hot Working/Forging
Low sulfur reducing furnace atmospheres should be used in forging. Major hot
working should be done between 2300/1850 Degrees F, while light working may be
continued as low as 1600 Degrees F. No hot working should be attempted between
1600/1200 Degrees F due to lower ductility in that range.
Machinability
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.
Cold Working
For higher properties, alloy 600 can be cold worked below 1200 Degrees F (649
Degrees C).
Welding
Alloy 600 can be joined by the usual welding, brazing, and soldering process.
