FIELD: metallurgy.
SUBSTANCE: invention relates to a manufacturing method of items from light austenitic structural steel with variable material properties in the item wall thickness direction with the following composition, wt %: C 0.2 to ≤1.0, Al 0.05 to<15.0, Si 0.05 to ≤6.0, Mn 9.0 to<30.0, iron and inevitable impurities are the rest with addition, when necessary, of Cr≤6.5, Cu≤4.0, Ti+Zr≤0.7, Nb+V≤0.5, B≤0.1.
EFFECT: item is subject to decarburising annealing in an oxidising atmosphere, which provides for formation of a ferrite or metastable austenitic structure in near-surface areas of the specified thickness of the layer and properties.
