Abstract: Effect of Nb content on oxidation resistance and tensile strength at 1 150 T of as-cast alloy HP40 ( % : 0. 40C, 25Cr, 35Ni, 0. 15Mo, 0. 05Ti, 0. 4 〜2. 1 Nb) melted by a 10 kg vacuum induction furnace has been studied by Gleeble-1500 thermal simulation machine. Results show that the HP40 alloy contained 0. 8% Nb has excellent comprehensive high temperature properties that is at 1 150 ℃ , the oxidation weight gain- 0. 766 g/( m2·h) is lowest and the tensile strength (52 MPa) is highest.
