Chemical Composition of Inconel 718 Flanges (UNS N07718 / Alloy 718)

The chemical composition of Inconel 718 (UNS N07718) is what gives it exceptional high-temperature strength and corrosion resistance. The alloy derives its superior mechanical properties primarily from the controlled addition of Niobium (Nb+Ta) and Molybdenum (Mo), which promote precipitation hardening. The high Nickel (50–55%) content ensures outstanding resistance to oxidizing and reducing environments, while Chromium (17–21%) contributes to surface stability at elevated temperatures. The table below lists the minimum and maximum elemental composition as per the ASTM B564 / ASME SB564 standard for Inconel 718 Flanges.

Mechanical Properties of Inconel 718 Flanges (Alloy 718 / ASTM B564)

Inconel 718 Flanges are engineered to perform reliably under extreme mechanical and thermal stress. As a precipitation-hardened superalloy, Alloy 718 (UNS N07718) delivers significantly higher tensile and yield strength compared to standard austenitic stainless steels, making it the preferred material for high-pressure piping systems in aerospace, oil & gas, and power generation. The table below provides the key mechanical and physical properties of Inconel 718 in both annealed and age-hardened (precipitation treated) condition as per ASTM B564.

Inconel 718 Equivalent Grades – UNS N07718 / Werkstoff 2.4668 / NCF 718

Inconel 718 is commercially known by various designations depending on the international standard or country of use. Whether it is referred to as Alloy 718, UNS N07718, Werkstoff Nr. 2.4668, or JIS NCF 718, the underlying material composition and properties remain the same. The table below provides a quick cross-reference of all internationally recognized equivalent grades for Inconel 718 Flanges, helping procurement teams verify material compliance across different global standards.

Dimensions of Inconel 718 Blind Flanges

This table provides the detailed dimensional data for Inconel 718 Blind Flanges manufactured to common ASME B16.5 standards. These measurements are essential for accurate piping layout, bolting alignment, and ensuring a proper seal.
