ASTM B444 Inconel 625/UNS NO6625 Seamless U-Bend Tube
The alloy 625 tubes, which are widely used for superheater or heat exchanger tubing, are generally manufactured as per ASTM B444 (ASME SB-444) UNS N06625. It is a typical nickel-chromium-molybdenum-columbium alloy, which is commercially known as a proprietary brand of “Inconel alloy 625“. The cold-worked alloy 625 seamless tubes may be furnished in two grades of different heat-treated conditions: Grade 1 (annealed) – tubes are normally employed in service temperatures up to 1100°F (593°C); Grade 2 (solution annealed) – material is normally employed in service temperatures above 1100°F (593°C) when resistance to creep and rupture is required. Generally, unless otherwise specified, Grade 1 will be supplied.
The cold-drawn alloy 625 tubes can be furnished with ground bright surfaces or pickled matte surfaces depending on the requirements of clients. Especially, small-diameter and light-wall tubes of UNS N06625 are widely used for heat exchanger or instrumentation tubing. The “small-diameter” refers to outside diameters 1-1/4″ (31.8 mm) and under, while “light-wall” refers to a tube with specified wall thickness 3% or less of the specified outside diameter.
