Product description and application

Hastelloy188 is a solid-solution strengthened diamond-based high-temperature alloy. Adding 14% tungsten solid-solution strengthening gives the alloy excellent high-temperature thermal strength. Adding a higher content of chromium and trace amounts of steel gives the alloy good high-temperature oxidation resistance. It has satisfactory process properties such as forming and welding, and is suitable for manufacturing aero-engine parts that require high strength below 980°C and oxidation resistance below 1100°C. It can also be used on aerospace engines and space shuttles. It can produce and supply various deformed products, such as thin plates, medium plates, strips, bars, forgings, wires and precision castings.
