2.4668 (N07718/Inconel718/GH4169) bolts can be classified into several types. Let me share with you:
2.4668 (N07718/Inconel718/GH4169) bolts belong to the category of thermal strength materials. With the development of industrial modernization, the parameters of power machinery continue to improve, and the working temperature of thermal strength materials has correspondingly risen to over 1000 degrees. 2.4668 (N07718/Inconel718/GH4169) bolts are the main components of turbochargers in internal combustion engines, steam turbines, aviation engines, and diesel engines, including turbine blades, guide vanes, intake valves, and exhaust valves. Or it can work at high temperatures, under stress, and come into contact with corrosive gases such as high-temperature steam, gasoline, diesel, heavy oil gas, and exhaust gas. Therefore, the materials used to manufacture these components must also have sufficient durability, creep strength, thermal fatigue strength, high-temperature toughness, and sufficient high-temperature chemical stability at high temperatures. High temperature alloys can meet these requirements. High temperature alloys are classified into three types based on their basic constituent elements.
1. Iron nickel high-temperature alloy
It refers to high nickel chromium iron-based alloys with nickel content higher than 20% and chromium content generally around 15%.
2. Nickel based high-temperature alloy
This is a nickel based alloy formed by adding small amounts of alloying elements such as aluminum, titanium, chromium, niobium, tantalum, tungsten, molybdenum, vanadium, zirconium, and appropriate amounts of rare earth elements. Of course, the high-temperature performance of nickel based superalloys is superior to that of high-strength steels, and they are widely used in applications with working temperatures ranging from 800 to over 1000 degrees Celsius, for manufacturing aviation gas turbine blades, large gas turbine blades, guide vanes, etc.
3. Cobalt based alloy
This is an alloy mainly composed of cobalt, with various alloying elements also added. Cobalt based alloys typically contain 5% to 30% nickel and have high austenite stability. Cobalt based high-temperature alloys have good plasticity, thermal fatigue strength, and stability during use, such as the guide vanes of gas turbines, which are mostly made of cobalt based alloys.
