Summary: | The invention relates to a steel for manufacturing a component by hot forming after austenization. The steel consists of in weight % less than or equal to 0.2 %, carbon (C), less than or equal to 3.5 % silicon (Si), 1.5- 16.0 % manganese (Mn), 8.0 - 14.0 % chromium (Cr), less than or equal to 6.0 % nickel (Ni), less than or equal to 1.0 % nitrogen (N), less than or equal to 1.2 % niobium (Nb) linked to the formula Nb = 4x(C+N), less than or equal to 1.2 % titanium (Ti) so that Ti = 4x(C+N) + 0.15, and further optionally less than or equal to 2.0 % molybdenum (Mo), less than or equal to 0.15 % vanadium (V), less than or equal to 2.0 % copper (Cu), less than 0.2 % aluminum (Al), less than or equal to 0.05 % boron (B), the rest being iron and evitable impurities occupying in stainless steels. The invention also relates to the steel in transportation parts of vehicles and in pressure vessels or tubes. |
