Аннотация:Principles for creating a new generation of steels for preparation of objects by hot stamping with an improvement of strength properties (ultimate strength up to 2200 MPa) by a factor of three are analyzed. It is shown that first of all they should be aimed at simultaneous provision of good steel hot ductility indices, quenchability, and hardenability. It is established that boron-containing steels, and also steels of the alloy and microalloy systems Mn–Cr, Mn–Mo–Nb, Mn–Cr–Ni–(Mo–Nb–V) with an attempt to reduce carbon content are most promising for this purpose. With the aim of verifying results obtained experiments are performed for the effect of cooling rate on steel strength properties of the alloy systems selected. Adequacy of the main conclusions and the promise of using boron for alloying, and also alloying and microalloying additions C–Mn–Cr–Ni–Nb–V systems in order to create new low-alloy weldable steels for preparation of objects by hot stamping are confirmed.
