Results of experimental researches about influence of structure of trumpet steel 20 on characteristics of resistance to destruction are resulted. It is shown, that with the purpose of achievement of the greatest possible characteristics of resistance it is necessary for destruction to determine dependence of these characteristics at a variation of a volume fraction of a strengthening phase and the attitude l/d.
