Inconel

 

a heat-resistant alloy based on nickel, containing approximately 15 percent chromium and up to 9 percent iron. It was developed in the USA, where it is manufactured in a number of varieties that are alloyed with aluminum, titanium, molybdenum, and other metals depending on use. Inconel is used as a construction material for components of gas-turbine engines, supersonic aircraft, rockets, and the like. The alloys are characterized by high durability and impact strength at temperatures up to 900°C and by insensitivity to gashes at low temperatures (to −78°C). Products made of Inconel are readily joined by welding; welded structures are subjected to heat treatment in order to increase durability. The alloy grades KhN80TBIu and KhN73MBTIu made in the USSR resemble Inconel.
