China Manufacturer of ASTM B166 Inconel 601 Round Bar N06601 Rod
What is Inconel 601?
Inconel 601 is a nickel-chromium alloy, that is highly resistant to oxidation through 2200°F. Inconel 601 is a nickel-chromium alloy used for applications that require resistance to corrosion and heat.
Inconel 601 is also known as N06601, 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 (%) of Nickel Inconel 601
The composition of the particular alloy is the following:
| Nickel | Chromium | Iron | Aluminum | Carbon | Manganese | Sulfur | Silicon | Copper |
| 58%-63% | 21%-25% | Remainder | 1%-1.7% | 0.10% max | 1% max | 0.015% max | 0.50% max | 1% max |
Mechanical and Physical Properties of Nickel Inconel 601
Nickel Inconel 601 has good mechanical strength, but its mechanical property changes depending on the form of the material. According to the manufacturer, the optimal temperature for this alloy is 1004°F (540°C) and above for solution-treated condition, and 1004°F (540°C) and below for annealed condition. Being used primarily in high-temperature applications, the Inconel Alloy 601 can retain its high tensile properties at higher temperatures, and it is not embrittled by extended exposure.
| Mechanical Properties | Imperial | Metric |
| Tensile strength (solution annealed, room temperature) | 110000 psi | 760 MPa |
| Yield strength (solution annealed, room temperature) | 65300 psi | 450 MPa |
| Elongation at break | 42% | 42% |
