Inconel 718 or alloy 718 or is the most commonly used grade of the hardenable Inconel nickel alloys. Because of it has been precipitation hardened, and its primary nickel & chromium composition, the alloy has a combination of outstanding corrosion resistance and high strength even at elevated temperatures.
Table of Content
Applications of the ASTM B637 UNS N07718 Bolts includes the following industries -
Processing of Natural gas - The equipment’s used during the processing of natural gas, come in contact with contaminants such as H2S or Hydrogen sulphide and CO2 or carbon dioxide. These contaminants when mixed with water, produce free chemicals like sulphur or carbonic acid, which are deposited on the walls or surface of the equipment and cause stress related cracking. ASTM B637 UNS N07718 Bolts are not affected by these compounds, hence they are used in the processing of natural gas, Down-hole oil shafts and wellhead parts.
The Aerospace industry also uses UNS N07718 Bolting for liquid oxygen turbo-pumps, gas turbine engines and airframe parts. These Alloy 718 Fasteners have a high performance in either cryogenic as well as elevated temperatures. The strength of these Inconel 718 Washers does not wane in spite of being exposed to extreme temperature ranges. Due to its good mechanical and physical performance in extremely cold environments, the Alloy 718 Bolts are used in Cryogenic tanks.
In Chemical processing plants, the Inconel 718 Screws provides really good resistance to corrosion due to the addition of nickel to its alloy. Additionally, the Inconel 718 Hex Nut finds use in high temperature applications like steam generators , gas turbines, rocket motors, spacecraft, pumps, tooling and nuclear pressurized water reactors. As compared to Inconel 625 fasteners, the Inconel 718 Hex Bolts are almost two times stronger.
Inconel 718 is also known to have excellent creep rupture strength at a temperature of up to 1300°F or 700°C. Although the Inconel 718 Stud Bolts can withstand elevated temperatures up to 1800°F or 982°C, the tensile strength of these Inconel 718 Stud Bolts could be improved further by cold working as per the AMS 5962 standard. Cold working Inconel 718 according to the fore mentioned standard can result in the alloy having a minimum tensile strength of 220ksi.
