Summary:The invention relates to the technical field of steel and iron materials and heat treatment equipment, in particular to anti-deformation CNRE rare earth heat-resistant steel for a heat treatment lifting appliance and a preparation method thereof. The anti-deformation CNRE rare earth heat-resistant steel for a heat treatment lifting appliance comprises the following chemical components by weight: 0.2-0.5% of C, 0.5-2.5% of Si, 5.0-10.0% of Mn, 15.0-25.0% of Cr, 1.0-6.0% of Ni, 0.05-0.50% of V, 0.05-0.50% of Nb, 0.2-0.5% of N, 0.005-0.5% of RE and the balance Fe. According to the rare earth heat-resistant steel, strong solid solution strengthening and precipitation strengthening effects are generated through C and N co-alloying and V and Nb micro-alloying, and the initial strength of a lifting appliance is improved; a high-temperature structure is stabilized by means of rare earth micro-alloying, the high-temperature strength attenuation rate is reduced, the high-temperature strength is improved, and the deform
