Реферат: An austenitic Ni-Cr-Fe alloy is provided as an exterior tube material for improved cracking and corrosion resistance of composite tubes used to construct the lower furnace section of kraft recovery boilers. The alloy consists of essentially, on a weight-% basis, 25-35 Cr, 5-15 Fe and 50-70 Ni, with other minor alloying elements and impurities such as are normally present in commercial alloys. This compositional range includes, as a preferred composition, the range corresponding to the commercial alloy 690 (UNS N06690).
