Abstract

PURPOSE: To obtain said tool steel of high tenacity and high wear durability by adding much carbon to marageing steel and further, adding more than one kind of Ti, Zr and Nb at a prescribed ratio.
CONSTITUTION: Said tool steel includes 3W20% Ni, 10W25% Co, 8W15% Mo, 10W25% of more than one kind of Ti, Nb and Zr, {0.7C<C<(0.25 Ti + 0.13 Nb + 0.13 Zr)} % C and the remainder of Fe in weight percent representation. As said steel includes necessary amount of Ti, Zr and Nb to form TiC, ZrC and NbC with the added carbon, it has high wear durability and high tenacity.
