High-performance super alloys made for challenging environmental conditions are Haynes 188 sheets and plates. They are extensively utilized in the chemical, power generation, and aerospace industries because of their exceptional strength, resistance to oxidation, and resistance to corrosion. Turbine blades, exhaust systems, heat exchangers, and parts for gas turbines are among the applications. The alloy’s resistance to oxidation and sulfidation prolongs component life, and its capacity to tolerate temperatures of up to 2,000°F (1,093°C) makes it appropriate for advanced industrial solutions, particularly in regions with high mechanical and thermal stress.
The cobalt-based superalloys known as Haynes 188 Sheets and Plates are mainly made up of cobalt (Co), chromium (Cr), nickel (Ni), and tungsten (W), with trace amounts of molybdenum (Mo), iron (Fe), carbon (C), silicon (Si), and manganese (Mn). The alloy can withstand temperatures of up to 2,000°F (1,093°C) without losing its mechanical stability. With a tensile strength that varies with temperature from 100 ksi to 150 ksi (690–1,035 MPa), it provides exceptional resistance to oxidation, corrosion, and creep. Additionally, Haynes 188 has exceptional weldability, guaranteeing longevity under harsh structural and thermal circumstances.
