UNS N07718 SEAMLESS PIPE

UNS N07718 Seamless Pipe refers to a type of seamless pipe made from Inconel 718, which is a high-strength, corrosion-resistant superalloy composed primarily of nickel (about 50-55%) and other elements such as chromium, iron, molybdenum, niobium, and titanium. The alloy is well-known for its ability to perform in high-temperature and highly stressed environments, making it suitable for various demanding applications, especially in aerospace, power generation, and chemical processing industries.
