Abstract

PURPOSE: To finely crystallize carbide by adding a specified amount of C, Si, Mn, Cr, Mo, V and N to steel, providing specified relations to the contents of the elements and the Mo and V contents. and further adding Zr.
CONSTITUTION: To steel are added, by wt., 0.35W1.4% C, 0.05W0.5% Si, 0.2W0.4% Mn, 3.5W4.5% Cr, 4W12% Mo, 1W3% V and <0.06% N.F≥7.42 is satisfied as the value of F of the equation, the relation of 12≥(Mo%)≥3(V%) is also satisfied, and 0.005W0.6% Zn is further added. The resulting steel contg. eutectic MC carbide is heat treated to make the carbide fine.
