Alloy 625

Nickel alloy bars to AMS 5666

Nickel-chromium alloy bar offering high-temperature strength.


Alloy 625 Nickel Bar

Also referred to as Inconel® 625.

Alloy 625 nickel-chromium alloy bar is developed for high-temperature strength and corrosion resistance.


Alloy 625 (often referred to as Inconel® 625) combines high strength and toughness with excellent corrosion resistance. Molybdenum and Niobium are added during the alloying process to strengthen the material. The result is a strong product that offers superior corrosion resistance in a broad range of corrosive media. The product also maintains these characteristics at elevated temperatures. Alloy 625 is resistant to oxidation and carburisation and offers excellent stress corrosion cracking resistance. Superior fatigue strength and weldability are also positive features. The alloy may be formed using various hot and cold forming methods.

Stock Availability
