The invention relates to metallurgy, in particular to methods for steels heat treatment. A method for martensitic steels heat treatment comprises the heating to the temperatures of diphasic austenitno-ferritnoy region and cooling. The heating to the temperatures of biphasic austenitic-ferritic region is carried out at 20-30 °C higher than An/As1/ point until production of 10-25 % remaining austenite. Before heating the normalization or tempering is carried out.
