Material Family

Nickel-Chromium Superalloy (Solid-Solution Strengthened)

Fundamental distinction from stainless steels. Offers superior high-temperature performance.

Common Designations

UNS N06600, Inconel 600, EN 2.4816, W.Nr. 2.4816, NS 3102

Global standard designations for procurement. "Inconel" is a registered trademark of Special Metals Corporation.

Chemical Composition (Typical wt.%)

Ni: ≥ 72.0 (Balance)
Cr: 14.0 - 17.0
Fe: 6.0 - 10.0
C: ≤ 0.15
Mn: ≤ 1.00
Si: ≤ 0.50
Cu: ≤ 0.50

High Nickel (Ni) provides inherent corrosion resistance and austenitic structure. Chromium (Cr) confers oxidation resistance.

Mechanical Properties (Annealed Plate)

Tensile Strength (Rm): 550 - 690 MPa
Yield Strength (Rp0.2): 240 - 345 MPa
Elongation (A): ≥ 30%

Robust strength maintained over a wide temperature range.

Physical Properties

Density: 8.47 g/cm³
Melting Range: 1354 - 1413 °C
Max Continuous Service Temp: 1175°C (2150°F) in oxidizing atmospheres.

Higher density than steel. Exceptional thermal stability.

Key Standards (Plate)

ASTM B168 (Standard Specification for Nickel-Chromium-Iron Alloy Plate, Sheet, and Strip)
ASME SB-168AMS 5540 (Aerospace)

ASTM B168 is the primary material specification for plate.
