Applications for Inconel 600

The alloy's strength and oxidation resistance at high temperatures thanks to its nickel and chromium content make it useful for many applications in the heat-treating industry. It is also a standard material of construction for nuclear reactors because the alloy has excellent corrosion resistance to high-purity water.

Alloy 600 Summary

lnconel® 600 is a nickel-chromium alloy designed for use from cryogenic to very high temperatures in the range of 2000 °F (1093 °C). It is a standard engineering material for applications which require resistance to corrosion, oxidation, and elevated temperatures so it is used in a variety of corrosion resisting applications. The high nickel content of the material provides exceptional resistance to chloride stress corrosion cracking. The chromium content of Alloy 600 grants the alloy resistance to sulfur compounds while also providing resistance under conditions where oxidation at high temperatures are a concern, or when the metal will be exposed to corrosive solutions. Nickel alloy 600 also has excellent resistance to nitrogen at high temperatures. This alloy can only be hardened and strengthened through cold work, however a wide variety of desirable mechanical properties can be obtained by combining cold working with thermal treatments.

Additional Properties

Inconel 600 Corrosion Resistance

Refer to NACE (National Associate of Corrosion Engineers) for corrosion resistance recommendations.


#1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. #2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA- Bright annealed cold rolled and bright annealed
#CBA- Course bright annealed cold rolled matte finish and bright anneal
#2 - Cold Rolled #2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished - Various grit finish for specific polish finished requirements.
* Not all finishes are available for all alloys - Contact Ulbrich Sales for more information.

Wire Finishes

XC - Extra Clean Bright Annealed or Bright Annealed and Cold Rolled Grease - Ultra bright finish (for decorative applications) Soap - Soap coating on tempered wire to act as lubricant * Contact Ulbrich Wire for custom wire finishes.
