Summary

The examination includes various tests with ten steel grades which varied in chemical compositions and microstructures. Cold deformation has great influence on mechanical properties of steels, as well as on the nil-ductility temperature. Strain ageing of steel lowers the nil-ductility temperature of examined steels. Normally measured nil-ductility temperatures of strain-aged steel are not enough conservative criterion for the application of that steel at low temperatures. In such a case it is better to use a reference nil-ductility temperature. Thus the paper presents certain reference nil-ductility temperatures for as aged steel.
