Haynes 188 bars are composed of several metals, including nickel-based superalloys and iron-based alloys. The specific composition varies depending on the intended application but typically contains elements such as chromium, iron, molybdenum, vanadium, cobalt, and tungsten. In addition to these essential ingredients, Haynes 188 bars can include micro-additions like calcium to enhance their high corrosion resistance capabilities further. The properties that make Haynes 188 bars useful in naval and aeronautical engineering also contribute to its overall chemical composition. This austenitic stainless steel alloy is renowned for its remarkable toughness and superior heat resistance at elevated temperatures.
Haynes 188 is an alloy containing chromium, molybdenum, and tungsten, suitable for use in high-temperature and corrosive atmospheres. This type of metal bar has been found to have excellent creep strength, fatigue resistance, and good thermal stability during long periods. Furthermore, 188 Haynes bars can also be used in many applications that require good wear resistance, such as gears and valves. Additionally, it is being increasingly utilized in aircraft engines due to its high-temperature capability thanks to its ability to resist oxidation and carry out gas exchanges at high speeds. Hence, Haynes bars 188 are an excellent option for any application that requires strength and durability.
