Abstract
A process for manufacturing a shaped steel product, comprising subjecting a steel to chromium, containing carbon in a proportion of up to 0.30%, chromium up to 6%, and nickel up to 3%, manganese up to 4%, or both, and optionally one or more of between molybdenum up to 4%, copper up to 1.25%, aluminum up to 1%, and silicon up to 1%, the rest being iron, apart from the impurities, with the proviso that the the contents of the constituents are correlated in such a way that they satisfy the following ratio 5 (% c) (% cr) (2/3 (% ni) (% mn) (% mo) 2/3 (% cu) 1/2 ( % al) 1/4 (% si) > = and having an initially martensitic structure, to the operations of (I) softening the steel by heating it above its recrystallization temperature but below its a1 temperature; (II) cool the steel to the desired temperature to shape it, (III) give the steel the desired shape, (IV) heat the formed product to a temperature higher than the temperature of the steel to make it austenitic; and (V) cooling the shaped structure.
