Abstract

The invention discloses a nickel-chromium high-resistance electrothermal alloy. The alloy is characterized by comprising the following components in percentage by mass: 0.02 to 0.06 percent of C, 0.010 to 0.020 percent of P, 0.010 to 0.015 percent of S, 0.02 to 0.60 percent of Mn, 1.00 to 1.50 percent of Si, 20.0 to 23.0 percent of Cr, 0.1 to 0.20 percent of Al, 0.4 to 0.8 percent of Fe, 0.1 to 0.20 percent of Ti, 0.20 to 0.50 percent of Zr, 0.01 to 0.05 percent of RE and the balance of Ni. Metal zirconium and a rare-earth material are added into a metal alloy, the zirconium is contacted with the air to form a zirconia protective layer, so that the surface oxidation resistance of the alloy is greatly improved; and moreover, far infrared rays can be generated, and heating is uniform, so that the highest operating temperature of the alloy steel can be up to 1,300 DEG C, and the surface load of the alloy steel can be up to 5 W/cm<2>.
