Inconel are a group of metals including the 718 Inconel Cold Rolled Plate which have one of the highest resistance to oxidation. This being said, the 718 Alloy Shim Sheet has the capacity to resist oxidation even when the alloy has been subjected to heat and pressure.

Apart from this the JIS NCF 718 Hot Rolled Plates possesses a high creep strength and can withstand an elevated temperature of up to 1300ºF. At such high temperatures usually other alloy grades such as carbon steels and aluminium would succumb to creep, unlike the ASME SB670 Alloy 718 Strip, which is built to last such an extreme environmental condition. As the alloy can be used in extreme temperature settings, the Werkstoff No 2.4668 Coils can be applied in those environments that have cryogenic temperatures.
The alloy has high temperature strength, which in turn has been achieved by precipitation hardening this nickel ASTM B670 UNS N07718 Cold Drawn Plate. The Alloy 718 Plate is often referred to as a Gamma double prime strengthened alloy with superior weldability. The Alloy 718 Sheet has outstanding resistance to post weld cracking, usually seen in welded alloy grades

The Inconel 718 is a nickel chromium alloy stabilized with cobalt, niobium and titanium. It is manufactured in different shapes and sizes. The rectangular plates and shim sheets are among the products. The shim is a thin piece of plate that is often used to fill in the gap or to level up the surface or to create gaps between two objects. The square plates on the other hand are produced according to requirements in perfect square shapes. They are used in making up platforms, surfaces and structures. In short, the shim sheet is cut in uneven sizes and shapes to fill in the gap where the square plates are ordered and applied in a predetermined square shape.
