Zusammenfassung: | The invention discloses stainless steel for a high-level liquid waste glass curing and packaging container. The stainless steel is prepared from, by mass, 0.05%-0.2% of C, 0.05%-0.5% of N, 0.2%-1.0% of Si, 18%-24% of Cr, 12%-17% of Ni, 0.03%-1.0% of Nb, 0-0.1% of Ce, 1.0%-2.0% of Mn, 0-10% of Mo + W, smaller than or equal to 0.3% of Co, smaller than or equal to 0.01% of S, smaller than or equal to 0.02% of P and the balance Fe. By adding C, N, Nb, Mo and W, the solid solution strengthening and multi-phase precipitation strengthening effects are achieved, the high-temperature strength is remarkably improved, meanwhile, Mo, W, N and Nb act jointly, the pitting corrosion resistance is improved, and the obtained stainless steel has good mechanical performance, high-temperature performance and corrosion resistance and is suitable for manufacturing of high-level liquid waste glass curing packaging containers and parts of the high-temperature field of the high-level liquid waste glass curing packaging containers.
