ASTM B444 UNS NO6625 Alloy Seamless Tubes for Boiler Calderas
YUHONG Group offers ASTM B444 UNS NO6625 SMLS alloy steel tubes and we sell these tubes in more than 70 countries up to now. 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.)
