FAQs about Inconel 601(UNS N06601)

Inconel 601 is a nickel-chromium alloy that is highly resistant to oxidation through 2200°F (1204°C). It offers high strength, outstanding thermal stability, and resistance to aqueous corrosion and high-temperature environments. It is particularly noted for its oxidation resistance and ability to retain a stable, adherent oxide layer which enhances its resistance to spalling.

  • Inconel 600 is primarily a nickel-chromium alloy known for its oxidation resistance at higher temperatures and good corrosion resistance to chloride-ion stress-corrosion cracking.
  • Inconel 601 has higher chromium content and an addition of aluminum which provides improved resistance to high-temperature oxidation compared to Inconel 600. It also has better mechanical properties at elevated temperatures.
  • Inconel 601 is designed for oxidation and carbonization resistance at high temperatures, with moderate strength.
  • Inconel 617 includes a higher chromium and nickel content, increasing its corrosion resistance and strength, particularly at elevated temperatures. It also contains cobalt and molybdenum which enhance its high-temperature strength and make it suitable for high-temperature applications, such as gas turbines.

Welding Inconel 601 requires:

  • Using matching filler material, typically a nickel-based superalloy welding rod.
  • Pre-cleaning the weld area to remove any impurities.
  • TIG (Tungsten Inert Gas) welding is recommended for its ability to provide clean and strong welds in nickel alloys.
  • Post-weld heat treatment may be necessary depending on the application to relieve stress.

Inconel 617 is commonly used in the aerospace industry and for power generation components due to its exceptional mechanical strength and creep resistance at high temperatures. It is also used in the manufacture of components for combustion cans, ducting, and heat-treating equipment.

In terms of high-temperature strength, Inconel 718 is one of the strongest Inconel alloys. It combines corrosion resistance with very high strength and good fabricability. It is widely used in applications that require high strength at temperatures up to 700°C.

  • Inconel 625 includes molybdenum and a substantial amount of niobium in addition to nickel and chromium which enhances its strength mainly through solid solution strengthening as opposed to precipitation hardening. It has superior corrosion resistance and fatigue strength.
  • Inconel 601 primarily relies on high nickel and chromium for oxidation resistance and does not include molybdenum or niobium. Its strength and resistance come from high chromium content and aluminum for oxidation resistance.
  • Inconel 718 is difficult to machine due to its work-hardening properties. The material hardens and strengthens at the cutting interface, making machining difficult without the appropriate cutting tools and parameters. It also has a high tendency to generate heat at the cutting point, which can affect tool life and machining efficiency.

Whether Inconel 600 is better than Hastelloy depends on the specific application:

  • Inconel 600 offers superior heat and corrosion resistance, making it ideal for heat-treating applications and uses involving exposure to corrosive environments at elevated temperatures.
  • Hastelloy alloys generally offer better chemical resistance, particularly to reducing environments, making them suitable for chemical processing applications where harsh acids are involved.


In conclusion, Inconel 601 (UNS N06601) is a distinguished alloy renowned for its superior resistance to high-temperature oxidation and corrosion, along with its robust mechanical strength.
