Inconel alloys are corrosion and oxidation resistant materials that are perfect for use in applications that need alloys that can withstand heat and pressure. When Inconel is heated, it forms a stable and thick oxide layer that protects surfaces from attack. It holds its strength over a wide range of temperatures, and is good in extreme heat applications where steel and aluminum would give way to creep. The word creep in this context means that those materials are apt to become permanently misshapen. Simply put it is an alloy that you want to use in anything that is going to be subjected to very high heat or extreme frigid temperatures. One of the largest industries where you will find the Inconel 718 bar being used is the gas and oil field.
The Versatility and Durability
In the 1980s, wells were being dug deeper and further down while drilling for oil and gas reserves. Digging at such depths caused steel and other metals to crack and break but testing was done and it was found 718 had a far greater resistance toward cracking, especially once it was treated by a specific heating process designed for it. It was also used for drill segments because of its strength and its protection from rust and corrosion.
The Creative Minds
The thought process behind finding a new material to solve some of the most pressing issues of the time came from oil companies in the Gulf of Mexico and Mississippi. They were looking for valves that could handle much more pressure than the ones they were currently using. Alloy 718 was decided upon because of its innate qualities of strength, resistance to rust and corrosion and the options of sizes it came in. One place you can find to meet all of your Inconel 718 needs is Sterling Aircraft Materials Ltd.
