Alloy 718 is a member of Inconel alloys which are chromium nickel superalloys. These are a family of superalloys that are resistant to most acid and dry gases at room temperature. The alloys perform well under very high temperatures are and corrosion resistant. They are resistant inside and outside water. Therefore most of these alloys could be used in sea water and marine environments. The Inconel 718 UNS N07718 has excellent tensile strength and impact strength. Therefore it could be used in applications that require strength and corrosion resistant. The alloy is designated by the standard DIN 2.4668. The material composition includes carbon, manganese, phosphorus, sulfur and silicon in addition to nickel and chromium. This is a low carbon version of the alloys with the allowed maximum carbon content is up to 0.08% of the composition. The Inconel 718 price fluctuates depending on the products and a full list could be obtained from us. The material can perform in lower cryogenic temperatures up to very high temperatures. The corrosion resistance is improved by the addition of 1% cobolt in the composition. The corrosion resistance and high temperature resistance properties land the alloy in the jet engine components and gas turbine blades. The alloy is produced through solid solution annealed conditions and therefore the Inconel 718 hardness is superior. The Inconel 718 heat treatment lasts for one hour at 982 degrees Celsius and the precipitation treatment lasts for 8 hours under 718 degrees Celsius. The Inconel 718 applications could be seen in the chemical, petrochemical, aerospace and marine applications. Although it could be used interchangeably with other grades of the Inconel superalloys, it is specifically used to produce components of jet engines and gas turbines. The Inconel 718 suppliers sell different forms, types and shapes of the material such as the bars, pipes and sheets.
