Section 1: Grade & Introduction
Inconel 600 (UNS N06600 / W.Nr. 2.4816) is a versatile nickel-chromium-iron alloy. It is widely recognized for its high strength, good workability, and excellent resistance to oxidation at elevated temperatures. The high nickel content provides the alloy with virtual immunity to chloride-ion stress-corrosion cracking, making it a standard material for demanding industrial applications.
Section 2: Chemical Composition
The performance of Inconel 600 is derived from its high nickel and chromium content. Below is the wt.% according to ASTM B168.
| Element | Content (%) |
|---|---|
| Nickel (Ni) | ≥ 72.0 |
| Chromium (Cr) | 14.0 - 17.0 |
| Iron (Fe) | 6.0 - 10.0 |
| Manganese (Mn) | ≤ 1.00 |
| Carbon (C) | ≤ 0.15 |
| Silicon (Si) | ≤ 0.50 |
| Copper (Cu) | ≤ 0.50 |
| Sulfur (S) | ≤ 0.015 |

Section 5: Others
Manufacturing & Processing
Inconel 600 can be both hot and cold worked. Annealing is typically carried out at 1010°C to 1150°C to soften the material and improve ductility after cold working.
Testing
Includes non-destructive testing such as Ultrasonic Testing (UT) for defects and PMI for material verification. Tensile and hardness tests are standard.
Applications
Used in furnace components (retorts, muffles), chemical processing (heater bodies, evaporator tubes), and the nuclear industry (control-rod components).
Global Cases
Supplied globally for high-temperature furnace liners and as a primary material in nuclear steam generator tubing.
FAQ
