Choose Inconel 600 Plate or Inconel 601 Plate?
Choose Inconel 600 Plate or Inconel 601 Plate?
For applications requiring superior high-temperature oxidation resistance, such as furnace components and radiant tubes, choose Inconel 601 sheet metal. For applications where high-temperature corrosion resistance and high strength are critical, but oxidation resistance requirements are not high, such as petrochemical equipment or nuclear reactors, choose Inconel 600 alloy sheet metal.
What are the applications of Inconel 601 alloy?
In industrial furnaces, this alloy is used to manufacture radiant tubes, furnace chambers, rotary kilns, flame shields, annealing tubes, woven conveyor belts, chain curtains, burner nozzles, and resistance heating elements.
Inconel 600 and Inconel 601 sheets are two commonly used nickel-based alloy sheets widely used in numerous fields. Although they belong to the same family of nickel-based alloys, they differ significantly in composition, properties, and applications. A thorough understanding of these differences is crucial for the correct selection and use of these two materials.
Inconel 600 and inconel 601 Material Chemical composition differences
| Element (wt%) | Inconel 600 | Inconel 601 |
|---|---|---|
| Nickel (Ni) | ≥72% | 58-63% |
| Chromium (Cr) | 14-17% | 21-25% |
| Aluminum (Al) | ≤0.3% | 1.0-1.7% |
| Iron (Fe) | 6-10% | Balance |
alloy 600 and alloy 601 High-Temperature Performance
| Property (800°C) | Inconel 600 | Inconel 601 |
|---|---|---|
| Max. Service Temp. | ≤925°C | ≤1100°C |
| Tensile Strength | ~260 MPa | ~350 MPa |
| Creep Rupture Life | Medium (<2,000h) | >5,000h |
| Oxidation Resistance | Moderate | Exceptional |
Corrosion Resistance of UNS N06600 and UNS N06601 Plates
Resistance of 601 Alloy and 601 Alloy Plates to General Corrosive Environments
Both Inconel 600 and Inconel 601 plates exhibit good resistance to corrosion in many conventional corrosive environments.
Chloride Resistance of 601 Alloy and 600 Alloy Plates
Due to the synergistic effect of chromium and aluminum in their composition, Inconel 601 exhibits slightly better resistance to chloride stress corrosion cracking than Inconel 600.
Oxidation Resistance of Inconel 601 Plates
This is a significant advantage of Inconel 601 over Inconel 600. The high chromium content (21-25%) and the addition of aluminum in Inconel 601 enable it to rapidly form a denser and more stable oxide film at high temperatures.
601 Inconel and 600 inconel sheet Fabrication & Economics Diffenence
| Factor | Inconel 600 | Inconel 601 |
|---|---|---|
| Weldability | Easy (30-45% elongation) | Controlled heat input required |
| Cold Formability | Better (lower yield strength) | Moderate (higher strength) |
| Plate Cost | Baseline | +15-20% (high Cr/Al content) |
| Replacement Cycle | 3-5 years (oxidizing env.) | 8-15 years (same conditions) |
| 5-Year TCO | ~$2.8M (illustrative) | ~$1.8M (saves $1M+) |
