Conclusions 1. Steel 20K with a Widmanstatten structure has higher strength and plastic characteristics as well as a higher impact strength than the steel with a granular ferritic-pearlitic structure. 2. At the same grain size the cold brittleness threshold of steel 20K with a Widmanstatten structure is 25–30°C below that of the steel with a granular structure. 3. The higher mechanical properties of the steel with a Widmanstatten structure are due to the fincgrained structure of the ferrite and the higher percentage of quasieutectoid. 4. The acicular form of ferrite in the microstructure of the steel cannot be the reason for lower mechanical properties.
