Anti-carburization high temperature-resistant electrothermal alloy

The invention discloses a carburization resistant and high temperature resistant electrical heating alloy, which comprises lower than or equal to 0.05 percent of carbon (C), lower than or equal to 0.30 percent of manganese (Mn), lower than or equal to 0.50 percent of silicon (Si), lower than or equal to 0.025 percent of phosphorus (P), lower than or equal to 0.020 percent of sulphur (S), 22.00 to24.00 percent of chrome (Cr), 5.00 to 7.00 percent of aluminum (AL), 0.10 to 1.00 percent of yttrium (Y), 0.10-0.50 percent of dysprosium (Dy), 0.10-0.50 percent of gadolinium (Gd), and residual ferrum (Fe). The combined properties of the carburization resistant and high temperature resistant electrical heating alloy are better than that of the prior art, the manufacture cost is low, and the imported carburization resistant and high temperature resistant electrical heating alloy can be replaced.
