The invention belongs to the technical field of heat-resistance alloy, and particularly relates to austenitic heat-resistance steel for a high activity waste container glass solidified body product container. The austenitic heat-resistance steel is prepared from, by mass, 0.02-0.1% of C, 23-26% of Cr, 18-22% of Ni, smaller than 1.0% of Si, smaller than 1.5% of Mn, 0.05-0.25% of N, 0.2-0.6% of Nb,0.2-0.6% of V, not larger than 0.04% of Al, not larger than 0.03% of Ti and the balance Fe. The contents of C and N are comprehensively controlled, while high-temperature strength is ensured, precipitation of grain boundaries M23C6 and Cr2N in the service process is reduced, and therefore it is ensured that materials have both the good strength and the good tenacity in the high-temperature serviceprocess. In addition, due to the reasonable ratio of the contents of C and N and the contents of V and Nb, the type and the morphology of a precipitation phase are controlled so that it can be ensured that materials have the good high-temperature strength in different temperature intervals, the primary NbC is not formed, and the tenacity cannot be reduced. By further reasonably controlling the Sicontent, separation of the sigma phase in the high-temperature service process is restrained, and the creep resistance of the materials is improved. Accordingly, the austenitic heat-resistance steelwith the good high-temperature strength and the good ductility and toughness after the high-temperature service is obtained.
