Alloy718 UNS N07718 2.4668 Inconel718 H41690 Material Summary
Inconel 718 is a nickel-chromium, precipitation hardening alloy that can maintain good ductility and high strength up to 1300°F. Inconel 718 has relatively good formability, weldability and excellent cryogenic properties compared to other PH nickel alloys. In addition, this alloy can be readily welded w/out hardening or cracking. Inconel 718 is non-magnetic and has good oxidation and corrosion resistance in aerospace applications.
Inconel 718 is a precipitation-strengthened superalloy. It has very high strength at medium and high temperature. Therefore, this alloy is often used in parts that need to be stressed at high temperatures. Inconel 718 has many applications in the aerospace field.
We manufacture Inconel 718 seamless pipe & tube according to ASTM B983. We have complete cold rolling, cold drawing, annealing, pickling and other process equipment. Any size and performance needs are guaranteed. We will carry out solution treatment and aging treatment on the material according to the standard requirements, which will ensure the best high temperature strength of the material.
