What is INCONEL 718 used for?

Inconel 718 is commonly used for cryogenic storage tanks, downhole shafts and wellhead parts.

Is INCONEL 718 hard to machine?

Inconel 718 is known to be among the most difficult-to-machine materials due to its special properties which cause the short tool life and severe surface damages.

Is INCONEL 718 a stainless steel?

Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a wide range of severely corrosive environments, pitting and crevice corrosion. This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition.

Is Inconel 718 brittle or ductile?

Inconel 718 is a nickel-based superalloy which has high mechanical strength at room temperature, high corrosion resistance, and excellent creep and fatigue resistance at high temperatures up to 650°C. Furthermore, it presents good resistance to corrosion and ductility at cryogenic temperatures up to − 250°C [4, 15].

How strong is Inconel 718?

As a result, materials usually become significantly stronger. In the case of Inconel, 718 has exceptional strength with a yield strength that is about 2x’s stronger than 625!

What is Inconel 625?

Inconel ® 625 is a nonmagnetic, corrosion and oxidation resistant, nickel-base alloy. Alloy 625 has high strength and toughness in the temperature range cryogenic to 2000°F (1093°C) which is derived largely from the solid solution effects of the refractory metals, columbium and molybdenum, in a nickel-chromium matrix.

What are the different grades of Inconel?

Inconel fasteners are commonly used for extreme environments and come in various “flavors” depending on the needs of the application. This brief paper will give you a quick comparison of the two most popular grades, Inconel 625 and Inconel 718 to help you choose the best material.

What is 718 steel used for?

In the case of Inconel, 718 has exceptional strength with a yield strength that is about 2x’s stronger than 625! Gas turbine and jet engines, cryogenic storage tanks, downhole oil & gas and nuclear engineering applications.
