High Strength Nickel Alloy Pipe Inconel 625 Alloy 625 ASTM B 444 ASTM B 829 ASME SB444

Inconel Alloy 625

Common Trade Names: Inconel 625, Alloy 625, Nickel 625, Chornin 625, Altemp 625, Nickelvac 625, Haynes 

625, Nicrofer® 6020.

INCONEL nickel-chromium alloy 625 (UNS N06625/W.Nr. 2.4856) is used for its high strength, excellent fabricability 

(including joining), and outstanding corrosion resistance. Service temperatures range from cryogenic to 

1800°F (982°C). 

Strength of INCONEL alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix; thus precipitation-hardening treatments are not required. This combination of elements also is responsible for superior 

resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature 

effects such as oxidation and carburization.
