Inconel617

Inconel 617 is worked in the temperature range of 1200 to 950°C (2190 to 1740°F), followed by water quenching or air cooling. Heat treatment after hot working is recommended for optimum performance. Cold forming Cold working should be performed on annealed material

Inconel 617 is particularly suitable where high temperatures and particularly high mechanical stresses are present. The alloy is recommended for operating temperatures up to 1000°C. Inconel 617 can be manufactured for thin-walled parts. Typical applications for Inconel 617 include industrial and aerospace gas turbine components, such as combustion tanks, housings, turbine rings and other components exposed to high temperatures. Air heaters, muffle tanks and radiation galleries high-temperature heat exchangers, valves and springs, the High-temperature gas-cooled nuclear reactors, such as high-temperature components of nuclear reactors - helium/helium media heat exchangers Chemical equipment, spiral tubes and pipes in petrochemical industry, etc. Inconel 617 is easy to hot and cold process, fabricate and machine. However, hot and cold working requires a lot of machine power due to the strength requirements of the material. Heating Before and during any heat treatment, the workpiece must be clean and free of any contaminants Thermoforming Due to the very high thermal strength, considerable force is required during the thermoforming process. Inconel 617 works in the temperature range of 1200 to 950°C (2190 to 1740°F) followed by water quenching or air cooling. Heat treatment after hot forming is recommended for optimum performance. Cold Forming Cold forming should be performed on annealed material.Inconel 617 has a higher work hardening rate than austenitic stainless steels. This should be considered when selecting forming equipment. Intermediate annealing is performed using high cold forming . After cold reduction of more than 10% or more than 5% in applications with temperatures above 900°C, solution annealing is required before use. Heat Treatment Solution heat treatment should be performed in the temperature range of 1150 to 1200°C. Water quenching is essential to achieve maximum creep resistance in Inconel 617. Thicknesses below 1.5 mm , which may require rapid air cooling applied stress relief annealing can be performed at temperatures up to 870°C. For any heat treatment the material should be loaded into the furnace at the maximum annealing temperature and the cleanliness precautions mentioned earlier in "Heating" should be observed. Descaling and pickling High temperature alloys form a protective oxide layer during use. Pre-oxidation in air improves corrosion resistance. Therefore, descaling should be checked according to the end use. Mechanical Processing Inconel 617 is best machined under solid solution treatment conditions. The high work hardening rate of this alloy should be considered, so only low surface cutting speeds and not too high feed rates should be selected.
