Nickel-based alloys are also named as ni-based superalloys with their outstanding strength, heat resistance and corrosion resistance in high temperature environment. Their face-centered crystal structure is a distinctive feature of ni-based alloys since nickel operates as a stabilizer for the austenite.They are widely used for their corrosion resistance and properties at dramatically elevated temperature. Whenever unusually severe conditions are expected one could consider these alloys because of their unique resistance properties. Each of these alloys is balanced with nickel, chromium, molybdenum, and other elements.
