摘要（英）：

The invention discloses a heat-resistant alloy resisting sulfur corrosion. The heat-resistant alloy is prepared from the following components in percentage by weight: 0.025-0.25 percent of C, 1.30-2.50 percent of Si, 1.00-2.50 percent of Mn, 20-30 percent of Cr, 17-27 percent of Ni, 0.75-2.50 percent of Nb, 0.6-1.50 percent of Mo, 1.0-2.5 percent of Al, 0.6-1.5 percent of V, 0.001-0.050 percent of Ce+La, at most 0.035 percent of P, at most 0.030 percent of S and the rest being Fe. The invention further discloses a rod production method of the heat-resistant alloy resisting sulfur corrosion. According to the heat-resistant alloy and the rod production method, the alloy rod has relativley high strength and good high-temperature sulfur corrosion resistance.
