ASTM B444 UNS NO6625 Nickel Alloy Steel Seamless U Bend Tubes for Calderas
YuHong Group as one of the leading suppliers in China to supply B444 NO6625 seamless nickel alloy steel u bend tubes.And we have many experiences in exporting.
Each U bend tube of our range is rigorously quality checked by our team of professionals on every produce of production to provide customers with defect-free quality products. These U-shaped bends can be custom designed in various diameters according to customer requirements and drawings.
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.
Inconel 625 has excellent strength at temperatures up to 816C. At higher temperatures , its strength is generally lower than that of other solid solution strengthened alloys.
Inconel 625 has good oxidation resistance at temperatures up to 980℃C and showsgood resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.
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.
Application: Boilers, heat exchangers, super heaters, condensers, furnase, chemical process industry, sea water application, etc,
