Are you interested in working with Pyromet 718? If so, there are some things that you should know about it. This is an alloy that is nickel-base and hardenable. It is able to display a very high yield, is tensile and has creep-rupture properties in temps up to 1300 degrees F or 704 degrees C. This is an alloy that is able to be hardened, which permits both welding and annealing without hardending during the cooling or heating process. This is an alloy with a very good weldability when it is compared to other nickel-based super alloys, especially those hardened by titanium or aluminum.
What is This Alloy Used For?
You may be wondering when Pyromet 718 bar is used for. In many cases, it is used in the aerospace industry, primarily in jet engines and aerospace parts like buckets, wheels, spacers and any fasteners or bolts that are subject to high temperatures. You will also find that these alloys can be used in both gas and oil drilling thanks to its great strength and resistance to corrosion, cracking and chlorides. You will also find, in the oil and gas industry, that these alloys are used in things like tubing hangers, valves, pump shafts, fishing tools, MWD/LWD parts and wellhead components.
What Type of Workability Should Be Expected?
When you work with this alloy, you should be aware of what type of workability you can expect. For instance, when it comes to hot working, you will find that you can use a temp up to 2050 degrees F, maximum. You will also find that using hot-cold working, between 1700 and 1850 degrees F or 927 to 1010 degrees F, you can improve the strength of the forge if you have a service temperature of below 1100 degrees F. You should soak during forging and you should be sure that the material is given some type of uniform reduction as to avoid the formation of any grain structures.
You can also easily weld this alloy in either aged or annealed conditions. When you weld in the aged condition, however, you will find that there is going to be a softened zone that has been heat-affected.
If you are interested in learning more about this alloy, you will definitely want to reach out to a retailer in your area.
