Inconel 601

Inconel 601 is similar to 600 in that its composition is nickel-chromium-iron, but the addition of aluminum differentiates it. Adding in the aluminum creates a higher resistance to oxidation than Inconel 600, and is often used in general-purpose engineering for high temperature conditions that require extraordinary resistance. It is commonly used in thermal capacities, industrial heat conditions and other operations requiring heat; the metal does not respond to heat conditions or treatments. Inconel 601 is also found in water environments; the metal shows high resistance to corrosion from water. Like Inconel 600, Inconel 601 only responds to cold-working practices and its mechanical properties are applicable for many areas of use. Therefore, it is classified as a super alloy/high performance alloy.
Also similar to Inconel 600, Inconel 601 is not recommended for environments with high quantities of sulfur. Its nickel content is too high and causes sulfurization of the metal. It is commonly traded under the names of Alloy 601 or Nickel 601.
