Haynes 263 is a high-temperature alloy that was developed by Haynes International, Inc. in the early 1980s. This nickel-chromium-molybdenum alloy has excellent strength and corrosion resistance at elevated temperatures, making it ideal for use in extreme environments.
One of the unique features of Haynes 263 is its ability to resist oxidation and scaling at temperatures up to 1800°F (982°C). This makes it an ideal material for gas turbine engine components, as well as other high-temperature applications in the aerospace, power generation, and chemical processing industries.
Anton Metal, a leading supplier of specialty metals, stocks a wide range of Haynes 263 products. In this article, we will explore the chemical composition, mechanical properties, standards, specifications, and applications of this remarkable alloy.
Chemical Composition of Haynes 263
Haynes 263 has a complex chemical composition that includes a variety of elements. The table below shows the chemical composition of Haynes 263:
| Element | Percentage (%) |
|---|---|
| Nickel | 47.5 – 50.5 |
| Chromium | 19.0 – 21.0 |
| Molybdenum | 14.0 – 16.0 |
| Iron | 3.0 – 6.0 |
| Cobalt | 1.0 – 3.0 |
| Tungsten | 1.0 – 2.5 |
| Titanium | 0.05 – 0.50 |
| Aluminum | 0.25 – 0.85 |
| Carbon | 0.05 – 0.15 |
| Boron | 0.015 – 0.040 |
| Zirconium | 0.02 – 0.12 |
As you can see, Haynes 263 contains a significant amount of nickel, which is responsible for its excellent resistance to corrosion and high-temperature strength. The chromium and molybdenum provide additional corrosion resistance and strength, while the other elements contribute to the overall performance of the alloy.
Mechanical Properties of Haynes 263
Haynes 263 has excellent mechanical properties at high temperatures. It has a high yield strength and tensile strength, as well as good ductility and toughness. The table below shows the mechanical properties of Haynes 263 at room temperature and elevated temperatures:
| Temperature | Yield Strength (ksi) | Tensile Strength (ksi) | Elongation (%) |
|---|---|---|---|
| Room Temperature | 130 | 290 | 40 |
| 800°F (427°C) | 58 | 128 | 50 |
| 1000°F (538°C) | 38 | 97 | 55 |
| 1200°F (649°C) | 24 | 60 | 60 |
| 1400°F (760°C) | 16 | 43 | 65 |
| 1600°F (871°C) | 10 | 30 | 70 |
As you can see, the strength of Haynes 263 decreases as the temperature increases, but it still maintains a significant amount of strength and ductility even at 1600°F (871°C). This makes it an ideal material for use in high-temperature applications where other materials would fail.
