摘要

Improvements in the manufacture of turbines, nuclear reactors and apparatus for the chemical industry, which have high characteristics up to temperatures of at least 1200ºC, a satisfactory resistance to oxidation and a good resistance to corrosion against hot acids, characterized by the employment in its construction of niobium alloys containing as essential elements at least 60% by weight of niobium, 1 to 5.5% of tungsten, 3 to 10% of titanium, 3 to 10% of vanadium, 1 to 5% of zirconium, 1 to 15% of hafnium and 0.01 to 0.5% of carbon.
