Alloy 625,INCONEL 625 Tube / UNS N06625 Tube,ASTM B444/ASTM B829 UNS N06625 PIPE,Inconel 625 Pipe

We are the professional manufacturer of ASTM B444 UNS N06625 PIPE,Inconel 625 Pipe in China.
ASTM B444 (ASME SB-444) UNS N06625 PIPE. N06625 is a typical nickel-chromium-molybdenum-columbium alloy, which is commercially known as a proprietary brand of “Inconel 625
Alloy 625/UNS N06625/Inconel 625  is a nickel-chromium alloy used for its high strength, excellent fabricability and outstanding corrosion resistance. Service temperatures can range from cryogenic to 980°C (1800°F). Alloy 625 strength is derived from the solid solution strengthening effect of molybdenium 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.
