This age hardenable nickel base super alloy has very good strength in temperatures up to about 980°C (1800°F). It’s strength is generally comparable to that of Rene 41 and is generally superior to that of Alloy 718 at temperatures exceeding 650 – 705°C (1200 – 1300°F).
Rene 41 is an age hardenable nickel base alloy that has very high strength at elevated temperatures, particularly within the range of 650 - 980 °C (1200 - 1800 °F). Required mechanical properties can be tailored by selection of various combinations of cold work and/or heat treatments. Rene 41 also has good oxidation resistance.
Haynes 282 is a new alloy developed for high temperature structural applications which has excellent creep strength in the temperature range of 650 – 930 °C (1200 – 1700 °F), surpassing that of Waspalloy and Rene 41. Haynes 282 possesses a unique combination of creep strength, thermal stability, weldability and fabricability that is not found in currently available commercial alloys. Its features make it suitable for critical gas turbine applications such as combustors, turbine and exhaust sections, and nozzle components.
Inconel® X750 is a Nickel-Chromium alloy made precipitation hardenable by additions of Aluminium and Titanium, having creep-rupture strength at high temperatures to about 700°C (1290°F). It is widely used for high temperature conditions but is not as strong as Nimonic 90, but Inconel® X750 also holds exceptional properties all the way down to cryogenic temperatures.
Nickel-Chromium alloy being precipitation hardenable and having high creep-rupture strength at high temperatures to about 700°C (1290°F). It has higher strength than Inconel® X-750 and better mechanical properties at lower temperatures than Nimonic 90 and Inconel® X-750. Inconel® 718 has exceptional weldability compared to the Nickel-base super alloys hardened by Aluminium and Titanium.
A Nickel-Chromium-Cobalt alloy being precipitation hardenable, having high stress-rupture strength and creep resistance at high temperatures up to about 950°C (1740°F). It is widely used and a well proven alloy in high temperature conditions. Some typical applications for Nimonic® 90 include turbine blades, discs, forgings, ring sections, hot-working tools and other extreme environments. Nimonic® 90 is also known as Superimphy 90, Pyromet 90, and Udimet 90.
Nimonic® 75 is a Nickel-Chromium alloy with good corrosion and heat resistance, and contains Titanium and Carbon as additives. Initially used as turbine blades in the 1940s, Nimonic® 75 is readily fabricated and welded, and is now more regularly used in gas turbine engines, industrial furnaces and nuclear engineering. Nimonic® 75 is also known as Nicrofer 7520.
