ASTM B444 Nickel Alloy Steel UNS NO6625 SMLS Bend U Tubes
YuHong can offer ASTM B444 NO6625 seamless nickel ally steel bend U
tubes and we sell these products with highest quality in more than
70 countries.
ASTM B444 This specification covers nickel-chromiummolybdenum-columbium
alloys (UNS N06625 and UNS N06852) and
nickel-chromium-molybdenum-silicon alloy (UNS N06219) in the form
of cold-worked seamless pipe and tube.
UNS N06625 products are furnished in two grades of different heat-treated conditions:
Grade 1 (annealed)—Material is 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.
(Note 1:Hot-working or reannealing may change properties significantly, depending on working history and temperatures.)
U tubes are manufactured by bending straight tubes, the process
bending is done cold on an automatic U-bend and to ensure tube wall
thinning and diameter ovality are controlled, tube bending is
accomplished with a mandrel inserted into the tube. Besides, the
U-bend of the U-tube is stress relieved under controlled conditions
and cycles for extended life.
Specifications
| Sizes / Thickness | OD:0.25"-24" W.T:0.02"-2.5" | ||||
| Manufacture | Tubes shall be made by the seamless process and Cold–Drawn, Annealed or Solution Annealed and Pickled (Not Ground) | ||||
| Heat Treatment | Seamless tubing immediately following hot forming may be
individually quenched in water or rapidly cooled by other means,
provided that the temperature of the tubes after hot forming is not
less than the minimum specifified solution temperature (direct quenched) | ||||

*Note: Not applicable to outside diameters under 1⁄8 in. (3.2 mm) and to wall thicknesses under 0.015 in. (0.38 mm). B Hot forming quality pipe and tubing is furnished to chemical requirements and surface inspection only. No tensile properties are required.
D: Annealed at 1600°F (871°C) minimum.
E: Solution annealed at 2000°F (1093°C) minimum, with or without subsequent stabilization anneal at 1800°F (982°C) minimum to increase resistance to sensitization.
