What is UNS N10276?
Alloy C276 (UNS N10276) is an austenitic nickel-molybdenum- chromium alloy with a small addition of tungsten. It is one of the premier corrosion resistant materials available for process industries. Alloy C276 has excellent corrosion resistance in both oxidizing and reducing environments.
What is the difference between Hastelloy c22 and C276?
Hastelloy is a representation of a family of corrosion-resistant alloys. Both C-22 and C-276 are from the Hastelloy family, and that similarity can lead to confusion, but C-22 has better overall corrosion resistance compared to C-276 and is often referred as the upgrade from C-276.
What is the composition of Hastelloy C276?
Chemical Composition
| Element | Content (%) |
|---|---|
| Nickel, Ni | 57 |
| Molybdenum, Mo | 15-17 |
| Chromium, Cr | 14.5-16.5 |
| Iron, Fe | 4-7 |
What is Hastelloy C22?
Hastelloy® C-22 is a most versatile nickel-chromium-molybdenum-tungsten alloy with improved resistance to both uniform and localized corrosion as well to a wide variety of mixed industrial chemicals. HC-22 has corrosion resistance superior to other Ni-Cr-Mo alloys including C-276, C-4 and 625.
What is the hardness of Hastelloy C276?
Corrosion Material’s C276 is a solid-solution-strengthened, nickel-molybdenum-chromium alloy with a small amount of tungsten, which exhibits excellent corrosion resistance in an assortment of harsh environments….Mechanical Properties.
| Tensile strength: | 530-730 | N/mm² |
|---|---|---|
| Hardness Brinell: | 230 | ≤ HB |
Are INCONEL and Hastelloy the same?
Comparing the two alloys, Inconel 625 has a higher chromium content, while Hastelloy C-276 has a higher molybdenum content. This makes them different in corrosion resistance in different environments.
Why Hastelloy is used?
The benefits of Hastelloy process equipment include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress corrosion cracking resistance, and ease of welding and fabrication.
