Abstract
A seamless austenite heat-resistant alloy tube of the present invention is made with a chemical composition comprising, in terms of mass percent, C : 0.03-0. 15%, Si ≤ 1%, Mn ≤ 2%, P ≤ 0.03%, S ≤ 0.01%, Ni: 35-60%, Cr: 18-38%, W : 3-1 1%, Ti: 0.01-1.2%, Al ≤ 0.5%, B : 0.0001-0.01%, N ≤ 0.02%, and O ≤ 0.008%; at least one chosen from Zr: 0.01-0.5%, Nb: 0.01-0.05%, and V : 0.01-0.5%; and, if necessary, at least one chosen from Mo ≤ 1%, Cu ≤ 1%, Co ≤ 1%, Ca ≤ 0.05%, Mg ≤ 0.05%, and REM ≤ 0 . 1%; with the remainder consisting of Fe and impurities. The average crystal grain diameter d µm at the central section of the thickness of the tube i s 1000 µm or less and fulfills the expression (d ≤ 1500 - 2.5 x 10 5 x B). The thickness of an oxide layer on the outer surface of the tube is 15 µm or less, and the outer surface of the tube is directly fillet welded. The alloy tube of the present invention has outstanding resistance to weld cracking and can suppress the appearance of cracks in the heat-affected zone during welding, and therefore can favorably be used as a member for high-temperature devices such as furnace wall pipes for boilers for electricity generation.
