What is material W.Nr. 2.4668?
W.Nr. 2.4668 is the material number (German material designation) for Inconel Alloy 718, a high-strength, corrosion-resistant nickel-chromium superalloy, also known as UNS N07718 and by various trade names such as Nickel 718. It is widely used in aerospace (jet engines, rockets) and the oil and gas industries.
What material is 2.4668 equivalent to?
2.4668 refers to the German (DIN/Werkstoff) designation for this high-performance nickel alloy, which is commonly known as Alloy 718, also called Inconel 718 (trade name) or UNS N07718. It is a high-strength, corrosion-resistant superalloy used in high-temperature environments in the aerospace and oil/gas industries.

What is the hardness of 2.4668 alloy?
The hardness of 2.4668 alloy (Inconel 718) varies significantly with heat treatment, but typically falls in the range of 34-40 HRC (Rockwell C) or up to 331 HBW (Brinell) for standard aged conditions, reaching up to 50 HRC (or higher) when cold-worked and aged for maximum strength. It's a precipitation-hardenable nickel alloy known for high strength and durability.
Is 2.4668 alloy magnetic?
No, Alloy 2.4668, also known as Inconel 718, is generally non-magnetic, meaning it doesn't attract to a magnet, making it useful for applications needing spark resistance or where magnetic interference is an issue, though some minor magnetic effects can occur under specific conditions like severe sensitization.
What is the difference between Inconel 625 and 718 composition?
Alloy 625 is primarily nickel-based, whilst Alloy 718 is nickel + cobalt (Ni+Co) based. The use of nickel + cobalt in Alloy 718 means that it has greater hardness and strength. Alloy 625, on the other hand, has higher levels of chromium and molybdenum, so it is more corrosion-resistant.
What is the difference between Inconel 600 and 718?
Inconel 600 excels in high-temperature oxidation resistance (furnace parts) with good moderate corrosion resistance, while Inconel 718 is the strength champion, offering superior tensile, fatigue, and creep strength for demanding aerospace (jet engines) and oil & gas (downhole tools) applications, thanks to its precipitation-hardening capabilities.
