2. Common Material Grade for Nickel alloy fasteners

Nickel alloys are a special class of metal alloys which contain a high content, often greater than 20% nickel. This makes them particularly useful in preventing corrosion from both acids and salt water environments as well as very stable in high temperature environments. As a result, nickel screws and bolts are best known for their unique combination of high strength and corrosion resistance at elevated temperatures. The most commonly used nickel alloy fasteners are:
In addition to nickel, many of these nickel alloys also contain specific amounts of chromium, molybdenum and iron which enhance their corrosion resistance, strength and high temperature stability. Having a higher chromium content helps to provide resistance to oxidizers and the addition of molybdenum enhances the resistance to reducing acids
