21CrMoV5-7 is a steel for fasteners with specified elevated and/or low temperature properties. Imanite has been designed for nitriding, giving similar hardness distribution as case hardening. When using nitriding the distortion due to quenching after carburising can be avoided. Imanite is a M-steel version of 21CrMoV5-7 . M-treatment is very beneficial when the machining is done in Q&T condition and the hardness is about 300 HBW.

1.7709, also known as 21CrMoV5-7+QT, is a low-alloy steel that is widely used in applications that require high-temperature strength and creep resistance. It is known for its excellent mechanical properties, including high strength and toughness, making it a popular choice for use in harsh environments.

1.7709 is commonly used in applications such as steam turbines, power generation plants, and other high-temperature applications. Its high-temperature strength and creep resistance make it a reliable material for use in critical components that are exposed to high-pressure and high-temperature conditions.

The material’s excellent mechanical properties are attributed to its unique composition, which includes chromium, molybdenum, and vanadium. These alloying elements give 1.7709 its high-temperature strength and resistance to creep.

In addition to its mechanical properties, 1.7709 is also known for its good weldability and machinability, making it a versatile material that can be easily formed and fabricated into various shapes and sizes.

Overall, 1.7709 is a reliable and durable material that is well-suited for use in high-temperature and high-pressure applications. Its excellent mechanical properties, good weldability, and machinability make it a popular choice for a wide range of industries, including power generation, oil and gas, and chemical processing.
