Alloy 230 (UNS: N06230)
Bellows Materials | Alloy 230 |
Trade Name | Haynes 230 |
Description | A nickel-chromium-tungsten-molybdenum alloy, designed to combine excellent high temperature strength, oxidation resistance (up to 2100 °F), nitriding resistance and long term stability. |
Application Notes | Alloy 230 is a solid-solution-strengthened material which combines excellent high-temperature strength with good fabricability at room temperature. It is particularly effective for prolonged exposure at temperatures of 1200 °F (649 °C) or more. |
Industry Uses / Products | Enduring temperatures as high as 2100°F (1149° C), HS 230 plates are ideal for aerospace applications, including Combustion cans, Gas turbine components Transition ducts |

Alloy 242 (UNS: N10242)
Bellows Materials | Alloy 242 |
Trade Name | Haynes 242 |
Description | An age-hardenable nickel-molybdenum-chromium alloy which derives its strength from a long-range-ordering reaction upon aging. |
Application Notes | It has tensile and creep strength properties up to 1300°F (705°C) which are as much as double those for solid solution strengthened alloys, but with high ductility in the aged condition. The thermal characteristics of 242 alloy are much lower than those for most other alloys, and it has very good oxidation resistance up to 1500°F(815°C). Other attractive features include excellent low cycle fatigue properties, very good thermal stability, and resistance to high-temperature fluorine and fluoride environments. |

Alloy 244
Bellows Materials | Alloy 244 |
Trade Name | Haynes 244 |
Description | A new Ni-Mo-Cr-W alloy developed for static parts in advanced gas turbine engines which require low thermal expansion at temperatures up to 1400°F (760°C). |
Application Notes | It offers a higher maximum use temperature than other low thermal expansion alloys currently available, including a 100-200°F (55-110°C) improvement over HAYNES® 242® alloy. The alloy is age-hardenable. |
