What is UNS N06600?

Inconel 600 is a nickel chromium alloy, which has good oxidation resistance at high temperature and good corrosion resistance in Carburizing and chlorine containing environment.
Inconel 600 is a nichrome alloy designed for low to high temperatures of 2000 degrees Fahrenheit (1093 degrees Celsius). The high nickel content of the alloy enables it to maintain a considerable resistance under reduction conditions and to resist the corrosion of a variety of organic and inorganic compounds. The content of nickel makes it have excellent resistance to chloride ion stress corrosion cracking, and also provides excellent resistance to alkaline solution.
Its chromium content makes the alloy resistant to sulfur compounds and various oxidation environments. The chromium content of the alloy makes it superior to industrial pure nickel under oxidation conditions. In strong oxidizing solutions, such as hot concentrated nitric acid, the resistance of 600 is very poor. Alloy 600 is relatively resistant to most neutral and alkaline salt solutions and is used in some corrosive environments. The alloy resists a mixture of steam and steam, air and carbon dioxide.

PERMISSIBLE VARIATIONS IN OUTSIDE DIAMETERA AND WALL THICKNESS Permissible Variations In Outside Diametera And Wall Thickness

• (1) Pipe and tube having a nominal wall thickness fo 3% or less of the nominal ouside diameter. The mean outside diameter shall conform to the permissible variations of Table 3 and individual measurements (including ovality) shall conform to the plus and minus values of the table, with the values increased by 0.5% of the nominal ouside diameter.
• (2) The mean ouside diameter for pipe and tube over 4 1/2 in. (114 mm) in outside diameter with a nominal wall thickness greater than 3% of the nominal ouside diameter shall conform to the permissible variations of this table, and individual measurements shall not exceed twice the permissible variations of the table.

• A. The wall thickness tolerances for hot-finished tubes includeseccentricity tolerance up to ±12.5%.
• B. For hot-finished 5 in. (127.0mm) and under in outside diameter, the tolerances on the ouside diameter apply for individual measurements and include ovality. For tubes over 5 in. ion outside diameter, the mean ouside diameter shall comform to the permissible variations of this table andindividual measurements shall not be twice the permissible variations for this table.

Heat Treatment of Inconel 600 (UNS N06600/Alloy 600)

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.

Workability of Inconel 600 (UNS N06600/Alloy 600)

Hot Working/Forging

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.

Machinability of Inconel 600 (UNS N06600/Alloy 600)

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 of Inconel 600 (UNS N06600/Alloy 600)

For higher properties, alloy 600 can be cold worked below 1200°F (649°C).

Welding of Inconel 600 (UNS N06600/Alloy 600)

Alloy 600 can be joined by the usual welding , brazing, and soldering process.
