Material Family

Nickel-Chromium-Iron-Aluminum Superalloy

The intentional aluminum (Al) content is the key to its superior high-temperature oxidation resistance.

Common Designations

UNS N06601, Inconel 601, EN 2.4851, W.Nr. 2.4851

Global standard designations for procurement.

Chemical Composition (Typical wt.%)

Ni: 58.0 - 63.0 (Balance)
Cr: 21.0 - 25.0
Al: 1.0 - 1.7
Fe: ~14.2
C: ≤ 0.10
Mn: ≤ 1.00
Si: ≤ 0.50

High Chromium & Aluminum form a stable, protective alumina (Al₂O₃) scale at extreme temperatures.

Mechanical Properties (Annealed Plate)

Tensile Strength: 655 - 895 MPa
Yield Strength: 275 - 585 MPa
Elongation: 30 - 45%
