Hastelloy is a family of high-performance alloys primarily made from nickel, with additions of chromium and molybdenum. These materials are known for their excellent resistance to corrosion and high-temperature strength, making them suitable for harsh environments, such as chemical processing and aerospace applications. The unique composition of Hastelloy allows it to withstand a variety of corrosive media, including acids and saltwater. This durability makes it a preferred choice in industries like oil and gas, pharmaceuticals, and power generation, where reliability and longevity are critical for equipment and components.
