FIELD: metallurgy. ^ SUBSTANCE: steel contains carbon, silicon, manganese, chrome, nickel, molybdenum, nitrogen, iron and unavoidable admixtures, at following components ratio, wt %: carbon 0.1-0.2, silicon 1.3-2.5, manganese 1.0-2.5, chrome 19.0-25.0, nickel 15.0-23.0, molybdenum 2.5-5.5, nitrogen 0.04-0.15, iron and unavoidable admixtures - the rest. Equivalents of austenite former and ferrite former are related by following dependence Aequ/FequëÑ0.85, where Aequ=%Ni+30%C+27%N+0.5%Mn, Fequ=%Cr+%Mo+1.5%Si. ^ EFFECT: steel hardening, it is provided receiving of stably antimagnetic austenitic structure with keeping of corrosion stability and nontoxility in oral cavity, manufacturability at manufacturing of dental prosthesis. ^ 2 tbl |
