Product Description

High temperature Inconel 718 plus hardened nickel-base alloy


Inconel 718 Plus (UNSN 07818) is a new hardened nickel-base alloy, this alloy is designed to have excellent comprehensive mechanical properties,good heat processing and welding properties, and appropriate cost below 700°C . The launch of the 718plus alloy effectively fills the long-standing gap between the two most widely used High-temperature alloys Inconel 718 (650 °C) and Waspaloy​ (750 °C).



The Inconel  718 plus was based on Inconel 718 to reduce the iron content by 18% to 10%, adding 9% cobalt and 1% tungsten, adjusting Al + Ti and Al/Ti, and appropriately increasing the niobium content, 718 Plus alloy overcomes the Insufficient requirements of the two alloy 718 and Waspaloy (GH4738),so that could be used at 700°C


718Plus alloy also has advantages over Waspaloy and other higher temperature capable, nickel-base alloys due to its higher strength, superior formability, better wear resistance, and a resistance to weld cracking. 718Plus alloy is a lower cost option than Waspaloy or Rene 41 alloy due to its lower intrinsic raw materials cost and improved hot workability which provides higher material yields, resulting in a lower cost finished part.

These products have been typically used for parts requiring high resistance to creep and stress rupture up to 1400°F(760°C) and oxidation resistance up to 1800°F(982°C), but usage is not limited to such applications.


At present, the alloy  718 Plus has been promoted and applied in several well-known aviation-engine companies, for plates, gates, fasteners, blades and so on.

The 718 Plus is also a commonly used material for copper extrusion mold.


Available forms

718Plus alloy is available in all product forms: ingot, billet, block, forged round bar, hot-rolled shapes and rectangles, bar, rod, wire, plate, sheet, strip, and castings.
