Inconel 601/ NiCr60/23 Strong Corrosion Resistant Super Alloy
Plate/ Sheet
Inconel 601 nickel-chromium-iron alloy is a general-purpose
engineering material for applications that require resistance to
heat and corrosion. The outstanding characteristic of Inconel 601
is its resistance to high-temperature oxidation. The alloy also has
good resistance to aqueous corrosion, has high mechanical strength,
and is readily formed, machined, and welded. The composition is a
face-centered-cubic solid solution with a high degree of
metallurgical stability. The alloy’s nickel base, in conjunction
with a substantial chromium content, provides resistance to many
corrosive media and high-temperature environments. Oxidation
resistance is further enhanced by the aluminum content.
- The most important property of Inconel 601 is resistance to
oxidation at very high temperatures up to 1250C. Even under severe
conditions such as, cyclical heating and cooling. This is possible
due to Inconel 601 having a tightly adherent oxide layer which is
resistant against spalling.
- Resistance to carburization is good, also resistant to carbon
nitriding conditions.
- Due to high chromium and some aluminum content, good resistance in
oxidizing sulfur bearing atmospheres at elevated temperatures is
demonstrated.
Inconel alloys are typically used in high temperature applications.
