Hastelloy G-50 Nickel Alloy
Hastelloy G-50 (UNS N06950) is a nickel-based superalloy. By optimizing the contents of chromium, molybdenum and cobalt, it performs exceptionally well in high-temperature oxidation and carburizing environments. This alloy is suitable for extreme high-temperature scenarios such as petrochemical cracking furnaces and heat treatment equipment, with a working temperature of up to 1150°C.
