Inconel 718｜ Alloy 718｜N07718｜Pipe and Tube
Inconel 718 (Alloy 718, UNS N07718/ 2.4668 / ), is one of the most widely used nickel-based super alloys. It consists of a combination of nickel – chromium – molybdenum elements. And it also corresponds to the UNS N07718 standard. This nickel-based super alloy, chemically open to NiCr19NbMo, has a high degree of corrosion resistance, which can be hardened by aging and maintains its mechanical properties even at different temperatures. And it has a very high tensile strength. It is a material with very high fracture resistance and resistant to high temperatures and reaches a harder structure after aging and hardening.
