Abstract��Effect of temperature used for quenching at 890��1040 �� on undissolved carbides and mechanical properties of Ultrahigh��Strength steel has been investigated.The results have indicated that impact toughness of experimental steel reached peak value as content of undissolved MC��carbides is significantly decreased, and increase of lath martensite packets size did not lead to a marked decrease in strength and toughness of steel when austenitizing temperature increased to about 1010 ��.
