Is hastelloy C276 the same as inconel C276?
Inconel 625 and Hastelloy C-276 are both nickel-chromium-molybdenum-based alloys. They all have excellent corrosion resistance and good strength.
Comparing the two alloys, Inconel 625 has a higher chromium content, while Hastelloy C-276 has a higher molybdenum content. This makes their corrosion resistance different in different environments.
This article will provide a detailed comparison of these two alloys from various aspects.
| Inconel 625 | Inconel 718 | |
|---|---|---|
| Density, g/cm³ | 8.44 | 8.89 |
| Density, lb/in.³ | 0.305 | 0.321 |
| Melting Range, °F | 2350-2460 | 2415-2500 |
| Melting Range, °C | 1290-1350 | 1323-1371 |
Inconel 625
INCONEL Nichrome 625 (UNS N06625 / W.Nr. 2.4856) is used for its high strength, excellent workability (including joining) and excellent corrosion resistance. Service temperatures range from cryogenic to 1800°F (982°C).
Hastelloy C-276
HASTELLOY C-276 alloy (UNS N10276) is the first wrought nickel-chromium-molybdenum material to alleviate welding problems (by virtue of its extremely low carbon and silicon content). As a result, it is widely accepted in chemical processing and related industries and has a 50-year record of reliable performance in a wide range of corrosive chemicals.
