Cryogenic Engineering Nickel Alloy Inconel 718 UNS N07718 2.4668 Alloy Strip/Foil With Stable Mechanical Properties

Product Introduction

Inconel 718 strip is a high-performance nickel-chromium-iron-based precipitation-hardened alloy strip with a wide range of applications in cryogenic engineering. The alloy performs well in the temperature range of -253°C to 700°C, with high strength, good toughness and excellent corrosion resistance. Its main components include nickel (about 50%-55%), chromium (17%-21%), niobium (4.75%-5.5%), molybdenum (2.8%-3.3%), etc., which enable it to maintain stable mechanical properties in cryogenic environments. The density of Inconel 718 strip is about 8.19 g/cm³, the melting point is between 1260-1330°C, the tensile strength is about 1400 MPa at room temperature, the yield strength is about 1150 MPa, and the ductility is about 25%. In cryogenic engineering, Inconel 718 strip is often used to manufacture cryogenic storage containers such as liquid nitrogen and liquid hydrogen, as well as structural parts that need to work under extreme low temperature conditions. In addition, the alloy also has good weldability and processability, and can be subjected to various forms of welding and machining in the annealed or aged state. These characteristics make Inconel 718 strip an ideal material choice in cryogenic engineering.
